Object life-cycles in active relational databases

One of the biggest problems that object-oriented developers face today is having to integrate at the enterprise level, object-oriented applications with widely applied and quality active relational databases. This paper focuses on the issues of mapping object dynamic behavior into active relational databases. We present a technique for expanding active relational databases with object-oriented behavior semantics, extracted from state transition diagrams expressing object life cycles. We consider states as first class objects, and discuss state class and event inheritance.
