Modelagem da informação com IDEF1X: linguagem, método, princípio do consenso

摘要

Information modeling deals with designing the information structure in a specific universe of discourse. It is a fundamental stage of database design. IDEF1X is a language and method for information modeling. It is based on the Entity-Relationship model. This paper presents a tutorial on IDEF1X, describing the main language constructs, and outlining the phases that comprise the method. The method’s criterion for the approval of information models, based on the consensus of experts in a universe of discourse, is discussed.
