Educational administration management is the primary link in the teaching management of colleges and universities. Mobile edge
computing can create a carrier-class service environment with high performance, low latency, and high bandwidth and accelerate
the rapid download of various contents, services, and applications in the network, which greatly promotes the upgrade of the
educational administration system. Using educational administration management system to manage educational administration
can promote the teaching work of colleges and universities better. is paper aims to design and develop a set of educational
management information systems, using mobile edge computing (MEC) technology to combine the IT service environment and
cloud computing technology at the edge of the network to improve the computing and performance of the edge network. Storage
capacity reduces network operation and service delivery delay, improves user service quality experience, and helps universities
improve the efficiency of educational administration management. is paper first discusses the implementation mode and related
technologies of educational administration management system, then discussing the demand analysis of each functional module
of the system; in the nonfunctional demand analysis part, the system needs to meet the security and performance. According to the
function modules included in the system, using the way of running interface screenshot, implementation code, and flowchart, the
paper analyzes the realization process of the function module and also completes the function test of the function module, as well
as the performance test of the whole system. e experimental results show that the rule 4 of teaching level evaluation data mining
reveals that the support degree of excellent teaching effect is 18% and the confidence degree is 53% in the age of 50–60. Rule 5
shows that the degree of support is 16% and the degree of confidence is 52%. Rule 10 shows that the degree of support for excellent
teaching effect is 22% and the confidence level is 71%. e high confidence level of backbone teachers aged 50–60 indicates that the
old teachers are more experienced and popular with students, while the young teachers under 30 need to focus on training to help
young teachers improve their professional level. From the above data, it can be seen that through the application of mobile edge
technology the educational administration system is more efficient in processing and analyzing data in terms of teacher
management and teaching level, which once again shows the impact of this network technology on the construction and de-
velopment of educational administration systems highly feasible.
1. Introduction
e progress of information technology has a significant
impact on the administrative work of colleges and univer-
sities. MEC technology can provide a virtual local area
network for campus hotspots and high-capacity scenarios.
rough business localization and local distribution tech-
nology, it can achieve efficient office and internal commu-
nication within the campus, thereby providing users with
low-cost, high-experience local connections and local
business access ability. rough the latest technology tools, it
promotes the development of student management towards
the direction of networking and digitalization and gradually
develops into the consensus of various colleges and uni-
versities. Digital campus is the use of computer technology,
network technology, communication technology, and sci-
entific and standardized management to integrate and
comprehensively digitize all information resources related to
teaching, scientific research, management, and life services
on the campus to form a unified user management, unified

resource management, and unified authority control. At this
stage, some colleges and universities in our country have
started and strengthened the development of digital campus,
vigorously built campus network, improved the hardware
equipment required by digital campus, and actively pro-
moted the improvement of the level of educational ad-
ministration management by introducing or self-developed
forms of configuration of educational administration
management information system. e current level of digital
construction of university educational administration sys-
tem is still at a relatively low stage. Traditional university
educational administration system deals with multifaceted
and multiangle data, and the planning system constructed is
often chaotic, which is inconvenient for information
management. e development of educational administra-
tion management information system in colleges and uni-
versities has a far-reaching impact on the development of
various activities in colleges and universities, which is
conducive to promoting the informatization and efficiency
of educational administration management, assisting leaders
to make decisions, and enabling teachers and students to
obtain more comprehensive information related to teaching
and scientific research, so as to reduce the burden of ad-
ministrative workers and effectively improve high efficiency.
With the rapid development of Internet, the expansion
of information restricts the effect of learning. Xiao Jun
designed a personalized recommendation system for edu-
cational video based on collaborative filtering recommen-
dation technology. e design of the system is mainly based
on collaborative technology and content analysis technol-
ogy. e system can not only improve the teaching effect, but
also improve students’ learning autonomy and make stu-
dents study efficiently. e system has been applied to the
lifelong learning network and achieved remarkable results
[1]. Abdulrauf Tosho describes a research related to the
conceptual design model, which aims at the design of
teaching interface to improve the utilization rate of
courseware. It is found that most of the existing courseware
applications focus on the needs of a certain goal and most of
the courseware contributes too little to the learners. In
addition, as a part of usability strategy, using structure,
layout, and navigation to improve courseware teaching
interface is also a problem for developers. e purpose of
this study is to establish an optional teaching interface,
which is called courseware teaching interface design (iid4c),
as a part of the usability strategy of inclusive education
system, for reference of developers and using comparative
analysis technology to determine the elements of the model.
Finally, the study found that iid4c model is useful for in-
formation access and is helpful for the design of teaching
courseware. e future work is to evaluate the proposed
model among disabled and nondisabled learners [2]. Roman
Yavich, in the framework of prescriptive theory, uses the
discipline design method to build a conceptual model of a set
of student training methods in the saturated environment of
information and communication. is enables them to al-
locate the stages of designing student training methods when
using virtual education environments. e results of this
paper reflect the general methods of teacher activity design,
including the design of training methods based on the
consideration of the main structural components of edu-
cational technology. rough the investigation of the
characteristics and opportunities of the virtual education
environment, we can make clear the rich nature of the
training method system and the mechanism of self-ad-
justment and self-improvement under the education in-
formation environment and make a conclusion that it is
impossible to create the modern education process without
the virtual education environment [3]. ese three scholars
have discussed the closeness of the connection between the
network and teaching from different angles. Some people
have constructed a new conceptual model of teaching
according to the current problems, making full use of virtual
technology, etc. However, their research is not compre-
hensively enough. However, there are still shortcomings in
the selection of technology applications, and the processing
of data needs to be strengthened.
is paper first discusses the overall structure design of
the system, including the design of the main function
modules, the overall structure chart and the main workflow
of the system, the detailed design of the system database, and
the overall design of the data mining process of the
achievements. Secondly, it discusses the process of mining
the teaching level evaluation data to obtain useful infor-
mation in the mobile educational administration manage-
ment system. e function test, performance test, usability
test, and security test are implemented in the mobile edu-
cational administration management system. Adopt B/s and
C/s model structure to reduce costs while maximizing
benefits and use J2EE technology multilayer model to extend
the service architecture; JSP technology provides multiple
efficient operation servers for the multiple models in this
article. All work arrangements are to create an intelligent
educational administration management system.
2. The Proposed Method
2.1. Implementation Mode of Educational Administration
Management System. Mode structure C/s and B/s: C/S
structure is client/server structure, which can reduce the
communication cost of the system [4]. However, the C/S
mode requires the support of the corresponding client of the
user host, so the software in this mode needs to develop the
corresponding software according to different operating
systems, which increases the development cost. At the same
time, with the acceleration of software update, the cost of
maintaining the software also increases accordingly [5, 6].
erefore, the whole system adopts the B/S (browser/server)
mode, which is convenient and efficient in management
software.
B/S structure is browser and server structure. It is dif-
ferent from the C/S structure, it does not need the user host
to install the corresponding client software, and users only
need a browser to browse and operate the working interface
[7]. Browser almost does not need to implement transaction
logic, mostly by the server-side implementation, forming the
so-called three-tier architecture. is can reduce the de-
velopment cost and the overall cost [8].
2Mobile Information Systems
According to the above introduction and analysis, the
construction of campus network adopts B/S structure, which
can realize the system relatively and simply and reduce the
development cost [9]. It can access the database in many
ways and protect the security of the data through the au-
thority control. is is also an important reason for using B/
S mode [10, 11].
Advantages of B/S mode are given as follows:
(1) e B/S mode turns the client into a browser,
through which the user can access the server.
(2) B/S mode can be directly placed on the WAN, which
is suitable for frequent interaction occasions and
easy to be accepted by users.
(3) B/S mode only needs to upgrade the server and adapt
the browser [12].
(4) e development of B/S mode has the advantages of
strong sharing and convenient business expansion,
and the expansion of web pages can increase the
function of no service.
(5) e B/S mode can release information on the net-
work, which is exactly what the educational ad-
ministration management system needs. e written
paper documents can be replaced by the electronic
documents, which not only save resources, but also
are convenient and fast and improves the office ef-
ficiency [13, 14].
2.2. Related Technologies
2.2.1. J2EE Technology. e full name of J2EE is Java2
Platform Enterprise Edition. Its essence is to provide an
application with a Java environment that can run on the
server side. It provides the basic framework environment
and API for application extension. As J2EE components and
service architecture have the same standards and specifi-
cations, it provides technical specifications and guidelines
for solving the conflicts between various products in the past
[15, 16].
J2EE also solves the shortcomings of the past C/s two-tier
mode. By layering, the business logic and interface display
are separated, making the software have better scalability
[17, 18]. At present, J2EE is mainly a typical four-tier model,
and the system is developed according to the four-tier
structure [19], as shown in Figure 1.
2.2.2. Servlet Technology. e client is actually a browser,
which does not need to be developed. JSP technology and
Servlet technology are needed in the network layer. Let us
introduce Servlet technology [20]. e full name of Servlet is
Java Servlet, which is a server-side program written in Java.
Its essence is the Java program running on the server
[21, 22]. Servlet is written in Java, so it has powerful
functions. It can not only process the client’s request, but
also return the response. Because of the combination of these
two aspects, it is very suitable to use Servlet in B/S mode
[23, 24]. In general, it has the advantages of good portability,
powerful function, good security, simplicity, high efficiency,
and durability [25, 26].
2.2.3. JSP Technology. JSP is the abbreviation of JavaServer
pages, in fact, it is a simple servlet, and it is a dynamic web
page technical standard [27]. It can insert Java language into
HTML syntax to make some data judgment or verification
[28].
As the current web page development technology, JSP
has the following characteristics compared with the static
HTML pages in the past:
(1) Separate the generation and display of content. is
can protect the code, and at the same time HTML
pages can easily adapt to most browsers.
(2) Strong portability: because many platforms support
Java, JSP can run on almost any platform.
(3) Use JavaBean technology to write every object or
business component, and then JSP page can use this
object or business component repeatedly.
(4) Precompiling is the first time that JSP pages are
accessed by users; they need to compile and save the
compiled results. After that, when they visit again,
they can run the saved compiled results directly
instead of precompiling, which can greatly improve
the access speed.
2.2.4. MVC Mode. e full name of MVC is model view
controller It is a three-layer software design model. e
application of the MVC pattern in the design of the edu-
cational administration system serves as a small skill to
propose solutions to specific problems in order to increase
the code reuse rate and reduce the degree of coupling. e
data information is planned into sange categories through
hierarchical levels, which is more specific and more clear.

in program development is handled in a separate way. MVC
design pattern is actually to decompose the problem through
layers and develop and solve the problem independently.
Simplify complex problems and reduce development diffi-
culties and complexity.
e architecture and design of the educational admin-
istration integrated management platform completely follow
the MVC mode, and Java technology is widely used in the
actual development.
Model: the core of MVC accepts the data of view request
and returns the final processing result. In order to make full
use of the existing components, the business model is further
divided from the perspective of application technology, but
it cannot be used as the framework of application design
model. e model in MVC design pattern includes not only
business model, but also function model and data model. A
model can be reused by multiple views, which improves the
efficiency of development and reduces the repetition rate of
code.
View: it is responsible for providing user interface (UI)
to the user. It is a model that hosts the information required
by the display controller. e model needs to be transformed
and presented to the user. In traditional web applications,
view is an interface composed of HTML, and the design is
relatively simple. In today’s web applications, view design is
more and more complex. One function corresponds to
multiple views, through which data is collected and cap-
tured. In ASP. Net MVC, view is passed to its controller and
modified content to HTML through the model object of state
register. Business process processing is done by model.
Control: the user receives the request, associates and
activates the model and view, and completes the user’s re-
quest together. When the request initiator is activated and
triggered, the controller does not operate. Its job is to receive
the request and select which model to call to process the
request and determine which view to use to display the
returned data.
e three-tier structure model of MVC design model,
the main functions and relations of view, and controller are
shown in Figure 2.
2.2.5. JavaBean Technology. JavaBean is to implement the
software component model in Java language. In the pro-
gram, these models are all a class. ese classes comply with
the JavaBean standard and have a unified specification.
Standard JavaBean components can be compared with
classes, and then these classes can be constructed and ap-
plied. Using this technology can make the code easy to
maintain, use, and write, also can realize code reuse, and
enhance code transmission.
2.2.6. Mobile Edge Computing Technology. Mobile edge
computing technology provides smart and cloud computing
capabilities for wireless access networks by deploying servers
on the wireless access side. Among them, the virtualized
infrastructure is based on physical resources such as com-
puting and storage of general-purpose servers. It provides a
flexible and efficient platform environment for multiple
applications to run independently for the application layer.
e software functional entities can be used to achieve
business localization and close-range processing; mobile
edge the platform is responsible for processing the basic
functions required by mobile edge applications, including
domain name, routing rule management and control, data
distribution, wireless network information management,
network self-organization management, big data analysis,
network acceleration, and business registration functions, of
which local distribution is business. e prerequisite for
application localization and short-distance deployment is
one of the most basic functions of the mobile edge com-
puting platform, so that the wireless network has the ability
of transmitting with low latency and high bandwidth. Short-
distance deployment is to give full play to the low-latency
advantages of mobile edge computing technology. Because
the distance to the user is closer, user requests no longer
need to travel through a long transmission network to reach
the remote core network to be processed but are processed
by the local MEC server. Part of the traffic is offloaded,
processed directly, and responded to the user, so the
communication delay will be greatly reduced.
2.3. Demand Analysis. Requirement analysis is to under-
stand what functions users want to achieve through soft-
ware. Requirement analysis needs to understand the user’s
requirements in detail, which has the function of decision-
making, direction, and strategy. e educational adminis-
tration management system is mainly to complete the needs
of the school educational administration work, including the
setting of courses, the storage, and management of basic
information such as student status, the admission of stu-
dents’ scores, and the management of teachers’ basic in-
formation, which requires a detailed and comprehensive
demand analysis of the school educational administration
management process and the design of a good management
platform. is section mainly introduces the design

principles, data flow, functional requirements, and non-
functional requirements of the system.
2.3.1. Design Principles. e educational administration
management system is based on the digital campus. In the
process of design and development, it needs to follow certain
design principles, not only to meet the basic principles of
software design, but also to meet the needs of educational
administration management, which is the basic requirement
of completing the system development with quality and
quantity. e following are the design principles followed by
the system design:
(1) Based on the overall planning, the system is based on
the process of educational administration manage-
ment and the specific functions are implemented
step by step.
(2) e design structure of the system is simple and easy
to maintain; Java programming is used to reduce the
difficulty and facilitate future maintenance and
update.
(3) e system divides users into administrators,
teachers, and students, which makes it more con-
venient to add, delete, modify, and check educational
information within their respective authority. So, it is
easy to operate and access.
(4) Security: the system ensures the security and reliability
of data through identity authentication, authority
management, and other measures to ensure the
normal and reliable operation of the system.
2.3.2. Main Workflow of the System. e workflow of each
user using the function module is as follows:
(1) Score entry: this function is a teacher function. After
logging in the system through the mobile intelligent
terminal, the teacher can choose to enter the score
entry page, enter the name of the class, the course
name, and the teaching time to start the score entry.
(2) Schedule query: this function is shared by teachers
and students. After the teachers or students log in to
the system, select schedule query, enter the query
interface, enter the class name to be queried, and
enter the class schedule. In case of special cir-
cumstances, teachers can view the class schedule
through this function and obtain the free time of the
class according to the schedule display. In addition,
teachers can also query the individual schedule
according to the work number.
(3) Classroom inquiry and reservation: this function is
a teacher function. After the teacher logs in to the
system, he/she selects the classroom inquiry and
reservation, enters the inquiry interface, enters the
use time, and selects the classroom type, and then
he/she will view the relevant information of the idle
classroom, including the classroom name and the
number of seats. e teacher selects the required
classroom according to the number of required
classes and the nature of the course. When booking
the classroom, the teacher enters the name of the
teacher, the name of the class, the time of class, and
the name of the course and selects the reservation.
e reservation information will be submitted to
the server.
(4) Course transfer application: this is the function of
teachers. After the teacher has reserved the class-
room, select the class adjustment application to
enter the class adjustment application interface and
select the class adjustment type, including two types
of options, class adjustment and arrangement due
to curriculum design, then enter the name of the
teacher, the name of the teaching class, and the
name of the course, and finally select the class
adjustment scheme. ere are two kinds of course
adjustment schemes. One is that the teacher adjusts
the time and place of class: input the original week,
day of week, and time of class, adjust the week, day
of week, and the name of the scheduled classroom,
and then submit the application for class adjust-
ment; the other is that the teacher adjusts the
teaching without changing the time and place of
class: input the week, day of week, time of class, and
the name of the substitute teacher and then submit
the application for class adjustment. Because the
front part of the application content is the same, the
system design will display two kinds of course
adjustment schemes in the same page.
(5) User management: this function is an administrator
function. After the administrator logs in to the
background system, he/she selects and enters the
user management page. For three different types of
users, the administrator can add, delete, or modify
users by category and assign permissions and
modify passwords to users.
(6) Course management: this function is an adminis-
trator function. e administrator can log in to the
system and enter the curriculum management in-
terface to create course information, add and
modify courses, classify courses, and complete
course arrangement.
(7) Classroom management: this function is an ad-
ministrator function. After the administrator logs in
to the system, he/she will enter the classroom
management interface. Classroom management
includes three submodules, input classroom,
classroom classification, and classroom reservation
management. e administrator can enter the
classroom classification module to classify the
existing classrooms according to the two categories
of used and free; mark the arranged and scheduled
classrooms as used and other free classrooms for
teachers to query and book. e administrator can
enter the classroom reservation management
Mobile Information Systems 5
module to count, mark, and delete the reservation
information.
(8) Notice management: administrators can add,
publish, and delete announcements after entering
the announcement management function interface.
(9) Performance management: teachers input students’
scores into the database according to the subjects
and class names they teach; administrators add,
delete and modify the scores, and manage the scores
of each student according to the class; that is to say,
connect and query the scores of each subject in the
class according to the student number and name to
generate a new class score table. e administrator
makes statistics and analysis on the scores of each
subject, and the score table can be directly called by
the score association rule mining subsystem. e
first stage of association rule mining must find all
high-frequency item groups of student performance
divided by subject and class from the original data
collection. Use the high-frequency k-item group in
the previous step to generate rules and perform
calculations, sorting, and classification under the
threshold of the minimum reliability condition.
(10) Student status management: the administrator
manages the student’s student status information,
including inputting the basic information of the
student’s student status, changing the student’s
student status information, modifying the student
status of the transferred majors, and deleting the
student status information of the students who have
left school or dropped out of school.
3. Experiments
3.1. Database Design. In the conceptual structure design
stage, this paper uses the total E-R diagram of the system to
describe the relationship between the entities involved in
the database. It is represented by an ellipse in the E-R
diagram, and entities with the same attributes have the
same characteristics and properties. e entity name and its
attribute name set are used to abstract and characterize
similar entities and use undirected edges to connect them
with corresponding entities; for example, the student’s
name, student ID, and gender are all attributes. If it is a
multivalue attribute, put a solid ellipse outside the ellipse.
In the logical structure design stage, this paper transforms
the E-R diagram into a relational model and finally designs
the table structure of the database. Based on the theory of
conceptual structure design of database, this paper analyzes
the demand of educational administration management
system and abstracts the entity of this mobile educational
administration management system, which mainly in-
cludes users, departments, classes, students, teachers,
courses, grades, classrooms, announcements, and class
transfer applications. After induction and analysis, E-R
model related to administrators and E-R model related to
students are, respectively, obtained. E-R model related to
administrators is shown in Figure 3.
e following E-R model related to teachers and students
is shown in Figure 4.
e detailed database structure design is shown in Tables 1
and 2.
3.2. System Test. Before the mobile educational adminis-
tration management system is put into use, it needs to test
the system performance according to a variety of test in-
dicators to check whether the system can operate normally.
Because of the use of HTML5, CSS3, jQuery, and other
popular but not very mature front-end development tech-
nologies, the openness required by HTML5 technology is
not up to standard, and the standards of related technologies
are not yet mature; CSS3 needs to be drawn and cut from the
beginning to achieve, and the follow-up workload is large;
jQuery is based on the data cache module to manage events,
and the style operation module is used to obtain calculations
style or set inline style. e system may produce many
unexpected problems in the use process, so we must test the
system functions in multiple directions and find out the
system defects as much as possible, e main focus of the test
of the educational administration management system based
on the mobile Internet is whether the system can work well
in different browser environments. e purpose of this
system test is to verify whether the system meets the user’s
requirements and complies with the system design re-
quirements, including development test, integration test,
and acceptance test. System test is to test the usability,
operation efficiency, and data integrity of the system by
using test tools according to the test process. e system test
includes function test, performance test, usability test, and
security test.

4.1. Design and Implementation
4.1.1. Design and Implementation of Login and Verification
Module. In this design, the system security measures are
taken to encrypt the user’s login password. After the client is
encrypted, the input login password needs to be compared

with the secondary encryption password stored in the server
before normal access to the system. In fact, the user’s use of
the system is not different from the original, but it really
enhances the security performance of the system. In this
way, it also means that two levels need to be passed before
the visit on the one hand for the user and on the other hand
for the system. First, the user’s identity is determined, and
then the database is checked.
After the user enters the user name (user account) and
password and verification code on the login page, the server
first determines whether the verification code is correct and
then determines whether there is a value matching the
user’s input account in the database user table. If there is a
user account in the database, the system will compare the
password field corresponding to the account with the
secondary encryption submitted in the form (twice via the
client and server MD5 encrypted) password. If the com-
parison is consistent, you can successfully enter the user
operation page corresponding to the type of user account
entered; otherwise, it will stay on the login and verification
page. e effect of the system login page is shown in
Figure 5.
4.1.2. Design and Implementation of Student Status Man-
agement Module. For the management of student status
after leaving school or leaving school, this graduation design
sets different query conditions for student status informa-
tion according to the two situations of leaving school. e
student status information of leaving school can be deleted
by selectively inputting grade to query all student status
information; and the student status information of

individual dropping out can be queried by inputting student
number to query relevant student status. e information is
then deleted. e interface of query management is shown in
Figure 6.
4.1.3. Design and Implementation of Announcement Man-
agement Module. After the administrator enters the page of
creating the announcement, the system can set the time of
creating and publishing the announcement through the new
attribute date time marked by HTML5 <input >. In the
drop-down list, the identity of the publisher can be selected.
After entering the title and the content of the announce-
ment, the creation of the announcement is completed. e
Modify button in the page plays the role of resetting the
content of the announcement. Click the Publish button to
publish the announcement to teachers and students. e
page effect of creating an announcement is shown in
Figure 7.
e key technology to realize the notification manage-
ment is to send the page. e application of this function is
embodied in adding a multilayer background image to an
element. e filtered data is scaled by a specified multiple, a
simple block is split into multiple columns, and the number
of columns, column widths, and blank spaces between
columns is realized through corresponding attributes. e
application of this attribute has greatly improved the
problem of multilayer layout in the past in the face of
multilayer design. is system calls the class SMS interface
provided by CSS3 to realize the sending function. e main
functions include the following: mobilelnfo service is used to
realize the session connection with the mobile client. CSS3’s
API calls sendsms (string telnumber. Stringmsg), a function
of public void type, to send page information. e function
setstratus() of type public void is used to record the sending
status; 0 is failed; 1 is sent successfully.
4.2. Implementation of Data Mining for Teaching Level
Evaluation. e average score of basic computer score is
extracted from the student score table of the mobile edu-
cational administration management system database as the
data voucher to evaluate the teaching effect of teachers. e
teaching effect of teachers is divided according to the average
score of basic computer score: 0 for below 60 scores, 1 for
between 60 and 70 scores, 2 for between 70 and 80 scores,
and 3 for above 80 scores. e teaching effect, together with
the data extracted from the teacher table, the teacher number
age, professional title, and education background, is con-
nected into the teaching effect information table, and the
relationship between the teaching effect of computer basic
courses and the professional title and education background
of teachers is found out from the teaching effect information
table through association rule mining. Table 3 shows some
teaching effect information.
According to the data in Table 4, age was divided into
four groups: A1 for 23–29, A2 for 30–35, A3 for 36–50, and
A4 for 50–60. Teaching effect is divided into four groups:
teaching effect 3 is x1, teaching effect 2 is X2, teaching effect 1
is X3, and teaching effect 0 is X4. Title: Z1 teaching assistant,
Z2 lecturer, Z3 associate professor, and Z4 professor; edu-
cation background: E1 undergraduate and E2 graduate. Part
of the information after data conversion to Boolean is shown
in Figure 8.
As shown in Table 5, Apriori algorithm is a frequent
itemset algorithm for mining association rules, and it is the
most influential algorithm for mining frequent itemsets of
Boolean association rules. Using layer-by-layer search and
iteration method, the core idea is to mine frequent itemsets
through two stages: candidate set generation and plot
downward closed detection. Its core is a recursive algorithm
based on the two-stage frequency set idea. After the data
preparation, the association rules in apriori algorithm can be
used to mine the relationship among teachers’ age, pro-
fessional title, education background, and classroom
teaching effect for the selected teaching effect information
with excellent teaching effect (teaching effect grade 3). When
the minimum support is 10% and the minimum confidence
is 40%, the association rules as shown in Figure 9 are
generated.
Rule 4 shows that, in the age group of 50–60 years old,
the support degree of excellent teaching effect is 18% and the
confidence degree is 53%. Rule 5 shows that the degree of
support is 16% and the degree of confidence is 52%. Rule 10
shows that the degree of support for excellent teaching effect
is 22% and the confidence level is 71%.
From the above rules, it can be concluded that, for
subjects with excellent teaching effect, the relationship be-
tween teaching effect and age, professional title, and edu-
cation background is as follows: young and middle-aged
teachers in the 30–50 age group have relatively high degree
of support and confidence in teaching effect, indicating that
they have relatively rich classroom teaching experience. e
high confidence level of backbone teachers aged 50–60 in-
dicates that the old teachers are more experienced and
popular with students, while the young teachers under 30
need to focus on training to help young teachers improve
their professional level. Teachers with professorship and
associate professorship as well as teachers with higher ed-
ucational background generally have higher teaching level.
Teachers with lower educational background and profes-
sional title still need further study in order to improve their
knowledge structure and professional ability.
4.3. System Test. (1) Function test of student subsystem.
e actual results in the function test case table
(Table 6) of student subsystem show that the func-
tion of student subsystem is normal. In the test for
the timetable query, the process of inputting the
information and clicking the query was carried out,
which can accurately and quickly display the page;
when the score is inquired, the timetable can be
displayed accordingly; the entire query process has
no errors, freezes, or delays phenomenon.
(2) Connection speed test: the mobile educational ad-
ministration management system mainly runs
through the mobile terminal in the wireless network,
and the data transmission speed will directly affect

the user experience. e mobile educational ad-
ministration management system has been tested in
the 4G mobile communication network and the
wireless LAN, respectively, and the response time of
the system is normal.
(3) Navigation test: navigation is the guide of system
operation. e design of system navigation is simple
and clear. Without training, users can smoothly use
the required functions through navigation to bring a
good user experience. rough the test of different
types of users to navigation links, it is confirmed that
the system navigation settings are scientific and all
levels of navigation styles are consistent.
5. Conclusions
e vigorous development of mobile edge computing has
created a good foundation for the wide application of
management information system. e management infor-
mation system based on B/S mode is bound to develop into
one of the main branches of information management. To
improve and upgrade the traditional system, it is the in-
evitable choice for colleges and universities to further
strengthen the educational administration management. e
management system based on B/S mode appears under the
condition of high popularity of mobile edge computing and
increasingly mature application of database. Compared with
the traditional C/S (client/server) mode, it is more perfect
and advanced and can well adapt to the new requirements of
information management in the Internet era.
is paper studies the demand of educational admin-
istration management in colleges and universities and finds
that the demand of educational administration management
information system currently used in colleges and univer-
sities is more, so it is difficult to undertake the imple-
mentation of educational administration management.
Under the background of the rapid development of infor-
mation technology, this paper designs and develops a set of
educational administration management information sys-
tems to help universities improve the efficiency of educa-
tional administration. e main work of this paper can be
summarized into three aspects: demand analysis, system
design, and the system implementation and system test.
is paper first discusses the design and implementation
of the login verification module and the implementation of
the password encryption storage and separately describes the
detailed design and implementation of the administrator
subsystem, including the student status management
module, the achievement management module, the design
and implementation of the achievement data mining, the
announcement management module, and the realization of
the paging function; then, it describes the design and
implementation of the teacher subsystem, including the
classroom query and the implementation of the specific
design and implementation of reservation module and CSS3
responsive layout; finally, it describes design and imple-
mentation of student subsystem, including the design and
implementation of score query module and HTML5 local
storage security mechanism.
