Mapeamento do modelo semântico de dados THM para o modelo relacional.

Abstract

All semantic modeling effort is wasted if it stays at the conceptual level without being passed to the operational level. The purpose of this paper is to explore the Temporal-Hierarchical Semantic Data Model (THM) and transfer to the operational level the semantics modeled with it. The mapping formalized here consists of translating the semantic concepts approached by THM into the Relational Model, with the objective of creating databases according to the application semantics and allowing them to be manipulated by conceptually defined operations, ensuring that they will not change. the integrity of the database.
