摘要：In today’s Environment. There is need of distributed database in communication. This provides a faster access and remove delays throughout the system .The paper will examine the features of distributed database architecture. The learning of distributed database management system will lead us for successful design. The design will improve scalability ,accessibility and flexibility while accessing data .In distributed System there is conflicts in real time performance and security can be unsolvable .This issue is Improved by allowing database to provide partial security violation so that real time performance is improved such as a covert channel at the time of failure. The main aim is to provide a efficient communication in efficient manner .This design also provide a non blocking communication between different levels. This design will improve a response time and delays throughout the system . In this paper we discuss partial security issues for a DDBMS
