Transformação de esquemas de objetos para um gerenciador relacional estendido, considerando o padrão ODMG.

Abstract

New database applications require additional features for behavioral and temporal modeling. Recently, new data models have been proposed to capture these aspects although there are yet no database management systems that support efficiently such facilities. Thus, to implement these applications using existing DBMSs, it is necessary to povide a proper mapping from the temporal data model to the underlying model of the adopted system. In this dissertation we propose a mapping approach to the modeling of an object-oriented temporal data model, called TOM (Temporal Object Model), using relational extended, whose this mapper conside the standard ODMG (Object Database Management Group). This approach makes possible to carry out the implementation according to the specific features of the ODMG and the existing DBMS. To illustrate the proposed approach, we discuss the implementation of mapper using the specific relational extended DBMS, OpenBASE.
