Descont-THM: um sistema para o desenvolvimento de esquemas conceituais de dados em THM (Temporal Hierarchic Data Model) baseado em frames.

Abstract

In this paper, the DESCONT-THM system, a tool written in PASCAL and oriented to the development of the static aspects of the modeling of conceptual data schemas for the THM (Temporal Hierarchic Data Model) system, is presented. This tool allows automatic schema retrieval of an application (discourse universe) for later mapping to the relational data continuity in the development phases of the implementation of the THM system. The system maintains friendly interaction with the user, providing a faithful semantic capture to the standardization of the THM model. For this it uses the frames model to represent the knowledge about the THM model, necessary for the process of inference that is performed by the system.
