Models are often used to represent various types of systems. This is especially true for software systems, where cooperating teams create models using a modeling language (e.g., UML). In cooperative modeling scenarios, it is useful to identify contributions and changes performed by individuals and teams. This paper presents a technique called CHECK...

Empowering end-users to program robots is becoming more significant. Introducing software engineering principles into end-user programming could improve the quality of the developed software applications. For example, model-driven development improves technology independence and adaptive systems act upon changes in their context of use. However, en...

When implicit typing with the “var” keyword was introduced into C#, it prompted contradictory opinions among developers. This paper starts by explaining the difference between implicit and explicit typing and then provides an overview of developers’ opinions and guidelines that are available online. This paper then reports on the results of a study...

Software requirements are an essential stepping stone for engineering any software system that meets the needs of its stakeholders. User interface (UI) contextual help provides end users with much-needed support for understanding how to use a software system. This article presents an approach for generating contextual help from software requirement...

Adaptive user interfaces (UIs) change their presentation at runtime to remain usable in different contexts-of-use. Such changes can cause discrepancies between the UI and static help materials, e.g., videos and screenshots, thereby negatively impacting the latter's usefulness (usability and utility). This paper presents Contextual Help for Adaptive...

Empowering end-users to wire Internet of Things (IoT) objects (things and services) together would allow them to more easily conceive and realize interesting IoT solutions. A challenge lies in devising a simple end-user development approach to support the specification of transformations, which can bridge the mismatch in the data being exchanged am...

Software applications that are very large-scale, can encompass hundreds of complex user interfaces (UIs). Such applications are commonly sold as feature-bloated off-the-shelf products to be used by people with variable needs in the required features and layout preferences. Although many UI adaptation approaches were proposed, several gaps and limit...

Adaptive user interfaces (UIs) were introduced to address some of the usability problems that plague many software applications. Model-driven engineering formed the basis for most of the systems targeting the development of such UIs. An overview of these systems is presented and a set of criteria is established to evaluate the strengths and shortco...

Many existing enterprise applications are at a mature stage in their development and are unable to easily benefit from the usability gains offered by adaptive user interfaces (UIs). Therefore, a method is needed for integrating adaptive UI capabilities into these systems without incurring a high cost or significantly disrupting the way they functio...

Enterprise applications such as customer relationship management (CRM) and enterprise resource planning (ERP) are very large scale, encompassing millions of lines-of-code and thousands of user interfaces (UI). These applications have to be sold as feature-bloated off-the-shelf products to be used by people with diverse needs in required feature-set...

The user interface (UI) layer is considered an important component in software applications since it links the users to the software’s functionality. Enterprise applications such as enterprise resource planning and customer relationship management systems have very complex UIs that are used by users with diverse needs in terms of the required featu...

Support tools are necessary for the adoption of model-driven engineering of adaptive user interfaces (UI). Enterprise applications in particular, require a tool that could be used by developers as well as I.T. personnel during all the development and post-development phases. An IDE that supports adaptive model-driven enterprise UIs could further pr...

Bloated software systems encompass a large number of features resulting in an increase in visual complexity. Enterprise applications are a common example of such types of systems. Since many users only use a distinct subset of the available features, providing a mechanism to tailor user interfaces according to each user’s needs helps in decreasing...

User interface (UI) adaptation is applied when a single UI design might not be adequate for maintaining usability in multiple contexts-of-use that can vary according to the user, platform, and environment. Fully-automated UI generation techniques have been criticized for not matching the ingenuity of human designers and manual UI adaptation has als...

Although proposed to accommodate new technologies and the continuous evolution of business processes and business rules, current model-driven approaches do not meet the flexibility and dynamic needs of feature-rich enterprise applications. This paper illustrates the use of interpreted runtime models instead of static models or generative runtime mo...

The main goal of this chapter is to demonstrate the design and development of a GUI framework that is model driven and is not directly linked to one presentation technology or any specific presentation subsystem of a certain programming language. This framework will allow us to create graphical user interfaces that are not only dynamically customiz...

The main goal of this chapter is to discuss the usage of spatial data within enterprise as well as smaller line-of-business applications. In particular, this chapter proposes new methodologies for storing and manipulating vague spatial data and provides methods for visualizing both crisp and vague spatial data. It also provides a comparison between...
