SBBO Based Replicated Data Allocation Approach for Distributed Database Design

Arjan Singh
2020 International journal of engineering research and technology  
The performance of any distributed database is heavily dependent on its proper design. Moreover, data allocation is an important part of distributed database design after data fragmentation.  ...  In the current scenario, when the demand of cloud based services and IoT devices is increasing day by day, designing distributed databases have become more challenging task.  ...  Fragmentation and allocation of data are two fundamental design issues in the design of a distributed database [31] .  ...

2011 arXiv   pre-print
By considering distributed database systems, we can allocate specific data fragments to the product useful to manage its own evolution.  ...  Intelligent products carrying their own information are more and more present nowadays. In recent years, some authors argued the usage of such products for the Supply Chain Management Industry.  ...  By considering distributed database systems, specific data fragments can be embedded/allocated on these products (for example, data useful for their life cycle).  ...
