TOP-DOWN APPROACH PROCESS BUILT ON CONCEPTUAL DESIGN TO PHYSICAL DESIGN USING LIS, GCS SCHEMA

Database is not static but rapidly grows in size. These issues include how to allocate data, communication of the system, the coordination among the individual system, distributed transition control and query processing, concurrency control over distributed relation, design of global user interface, design of component system in different physical location, integration of existing database system security. The system architecture makes use of software portioning of the database based on data clustering, SQMD (Single Query Multiple Database) architecture [1], a web services interface and virtualization software technologies. The system allows uniform access to concurrently distributed database, using SQMD architecture. In this Paper explain Design Strategies of Distributed Database for SQMD architecture.
