Section 2 specifies object oriented database system; section 3 incorporates authorization rules into database and section 4 maps the specification into a logic programming language and implements the language. Section 5 concludes the paper. The integration of object-oriented programming concepts with databases is one of the most significant advances in the evolution of database system, therefore the problems involved in providing data security for object oriented databases have been receiving very great attention from researchers. As a matter of fact, data are the most sensitive part of any system and its loss or compromise can have disastrous consequences. We discuss three different types of access: discretionary access control (DAC), mandatory access control (MAC) and role based access control (RBAC) in relational DBMS and object oriented data bases. We have identified some of the issues and current proposals; current security models in object oriented database systems and outline possible direction issues for future research.
