Authorization analysis of queries in object-oriented databases
[chapter]
1995
Lecture Notes in Computer Science
Preserved Fulltext
A simple model for method-based authorization is defined and an algorithm is presented for testing in compile-time whether a given database schema violates authorizations. ...
A method body is simply a sequence of statements. There are three types of statements: an access to an attribute of the self object, a method invocation, and a built-in operation on basic values. ...
Recently, various access control models for object-oriented databases (OODBs) have been proposed (see [4] , which is an excellent survey). ...
