TV_ODMG: Uma Extensão do Padrão ODMG com Suporte para Tempo e Versões

This work presents an extension of the ODMG standard, called TV_ODMG. This extension aims to support object versioning and temporal features, like transaction and valid times. The extension is based on the Temporal Versions Model, an object-oriented data model that keeps object versions and, for each version, the history of the dynamic properties values. Therefore, some components of the ODMG architecture were extended, like the Objects Model, the ODL and the OQL.
