Abstract

The concept of context in an object-oriented database model is first presented in this paper. A context is an associative abstraction of the schema which consists of a structure, rules and methods. A connection function is used to compute objects associations according to the context structure and rules. Then the concept of dynamic context is introduced. A dynamic context is composed of context versions and allows to model objects life-cycles. A Petri Net describes conditions under which objects may go from one context version to another.
