Integration of Multidatabases in Heterogeneous Environment Using NDBC Protocol

A multidatabase system (MDBS) is a collection of databases interconnected to share data. It provides integrated access to heterogeneous and distributed databases along with a single layer to facilitate end user by a set of different database systems. One of the major tasks in building a multidatabase system, is determining and integrating the data from the different database systems into a coherent global view. The current development of multidatabase systems undergoes many obstacles, one of these obstacles is the requirement of central or distributed schema that aids in integration of logical data relationships. This paper addresses the need for integration of multidatabase system by using NDBC protocol and proposes the algorithm for the implementation of xDB system components.
