Extending OODB with behavioral temporal management capability

In order to manage the history of objects in database, some researchers proposed the temporal database systems. However, data change is always caused by behavior of objects. A database application may not only need the data history of objects but also need the behavioral history of objects. Current temporal databases only consider the data history of objects but do not take the behavior history of objects into account. The purpose of this paper is to extend the capability of current object-oriented database such that the database have the capability to manage the data history and behavioral history of objects. To achieve this goal, we devised a data model, query language, and a storage system to accomplish it. A prototype system is developed on the Gemstone object oriented database system.
