摘要：This paper will examine the underlying features of the distributed database architecture .Learning the task of distributed database management system will lead us to a successful design. The design will improve scalability, accessibility and flexibility while accessing various types of data. Developing a successful distributed database system requires to address the importance of security issues that may arise and possibly compromise the access control and the integrity of the system. We propose some solution for some security aspects such as multilevel access control, confidentiality and reliability that pertain to a distributed database system. The aim of a distributed database management system (DDBMS) is to process and communicate data in an efficient and cost-effective manner. It has been recognized that such distributed systems are vital for the efficient processing required in military as well as commercial applications. For many of these applications it is especially important that the DDBMS should provide partial security. For example, the DDBMS should allow users who are cleared at different security levels access to the database consisting of data at a variety of sensitivity levels without compromising security. In this paper we discuss partial security issues for a DDBMS.
