Abstract

The Temporal Versions Model (TVM) is an Object Oriented Data Model developed to store the object versions and, for each version, the history of its dynamic attributes and relationships values. In this work, we propose a query language for this model. The language, called Temporal Versioned Query Language - TVQL, is based on SQL, adding new features to recover temporal information and versions. An alternative to its implementation on top of a commercial database is also presented.
