Derived horizontal fragmentation, Database Management System

Assignment Help:

Derived horizontal fragmentation:Some applications may include a join of two or more relations. If the relations are stored at dissimilar locations, there may be a major overhead in processing the join. In this type of cases, it may be more appropriate to make sure that the relations or fragments of relations that are joined together are at the similar location. We can get this using derived horizontal fragmentation.
