Resumo:
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.
