Questions related to Distributed Databases
The future of blockchain-based internet solutions
Blockchain is defined as a decentralized and distributed database in the open source model in a peer-to-peer internet network without central computers and without a centralized data storage space, used to record individual transactions, payments or journal entries encoded using cryptographic algorithms.
In current applications, blockchain is usually a decentralized and dispersed register of financial transactions. It is also a decentralized transaction platform in a distributed network infrastructure. In this formula, blockchain is currently implemented into financial institutions.
Some banks are already trying to use blockchain in their operations. if they did not do it, other economic entities, including fintechs, implementing blockchain could become more competitive in this respect. However, cryptocurrencies and a secure record of transactions are not the only blockchain applications. Various potential blockchain applications are being considered in the future.
Perhaps these new, different applications already exist in specific companies, corporations, public institutions or research centers in individual countries. In view of the above, the current question is: In what applications, besides cryptocurrency, blockchain in your company, organization, country, etc.?
I invite you to the discussion
Thank you very much
I want to perform database operations in distributed database environment. If somebody have idea relating to it. Please share.
Thanks in advance.
- What are the pros and cons of Smart contracts?
- What are the latest technologies and tools?
- What do you like and/or dislike about smart contracts?
It's an open discussion to help improve our understand of future technologies. You are welcome to share your opinions and experience.
Please suggest me commercially available Multidatabase System. Commercially available integration tools ETL (Materialized) / Mediated for both homogeneous and heterogeneous distributed databases.
Now they talk a lot about the technology of blockchain and distributed databases, etc. Is this really a unique innovation that did not have analogies in the "precomputer" era? Can you name effective examples (from the world history) of the existence of decentralized economic or social systems (infrastructures) that could provide for their own stable development for a long time?
It's the problem I have to solve, I don't have much knowledge about Distributed database, can any one help me?
can any one here guid me to system or solution allow creating DB in web base interface or from web base solution and ingest the data from third party system.
Thanks in advance
We are working on a concept of blockchain an discuss about the set up technical architecture and choose stack. Since blockchain is a full decentralized solution we look for NoSQL(i.e Cassandra) or other tools, methods etc. We are new in the topic. Appreciate suggestions and insights. Thanks a lot!
Actually, I am planning to use the concept of priority inheritance in distributed real-time database systems but I am not sure about which one of these two options( Priority Ceiling Protocol and Priority Inheritance Approach) will be best and on what basis.
I want to find out how many modes are present in data distribution. As per my search I found many methods for testing whether a distribution is unimodal or multimodal but I am interested in finding out number of modes available in distribution. Can any one suggest me how to estimate this?
Someone can help me to find some information or some papers about how Facebook uses big data, including Hadoop ?
I try to find, but can't find anything..Someone help me..
Big data is enormous, complex, comes at a faster rate and sometimes unstructured. Due to this aspect It is possible that an adversary can commit a digital crime without trace. Once you are able to secure the huge amount of Big data, how will you base your mode of segregation? Are you aware you might be filtering what should be actually what you are looking for?
I have developed a CBIR system, i have computed its precision and recall over 20 queries on database of 176 image database.
Tha attached, MAP (Mean Average Precision) and MAR (Mean Average Recall) of the proposed system.I would like to understand why the recall has low values than the precision. What is the suggested solutions to overcome this problem?
I am a newbie to hardoop. I want to be able to work with different high dimensional datasets and be able to process it to find summarized metrics for specific parameters of my choice.
I mean if you use the NoSQL than make any upgrades/ replace one machine will not have any effect on user due to its distributed nature is RDBS able to behave in similar way in the future?
The question might be very basic, but still I want to get a clear idea of why control of most of the VSI inverters are done in "dq" reference frames?
Also I would like to know, how the reference value of dq components (Vdref, Vqref etc.) are selected for the design purpose?
Kindly give me some resources of the same.
I want to compare diff database solution with respect to distributed database features availability.
