Managing fragmented database in distributed database environment / Ainul Azila Che Fauzi ... [et al.]

One of the mechanisms for managing data is replication since it improves data access and reliability. However, the amount of various data grows rapidly since technology is widely available at a low-cost. Problem arises when the transactions only work with a part of the database, not as a whole.This paper will discuss about a technique called database fragmentation. Fragmentation in distributed database is very useful in terms of usage, reliability and efficiency. Handling fragmented database replication becomes a challenging issue to administrators since the distributed database is scattered into split replica partitions or fragments. We address how to build a reliable system by using a distributed database fragmentation algorithm. The result shows that managing database replication with fragmentation will help a transaction to work with the specific part of the database rather than the entire database.
