Discretionary and Multilevel Security for Object Database Systems
Bhavani Thuraisingham · Auerbach Publications eBooks · 2005
Parts II through VI discussed discretionary and mandatory security for databases and distributed databases mainly based on the relational data model. In particular, we discussed discretionary security mechanisms, mandatory security mechanisms, designs of MLS/DBMSs, secure data models, the inference problem, and secure distributed database management with the relational model in mind. However, many of the discussions and arguments can be extended to nonrelational database systems. Most popular among the nonrelational database systems are object-oriented database systems. At one time there was a belief that object databases would supersede relational databases. Although that has not happened, relational databases have become more powerful by incorporating support for objects. Such databases are called object-relational databases.
