Extending OODB with behavioral temporal management capability

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