Summary:Considering the current legal framework, higher education institutions, with the intention of automating processes, integrating, and standardizing information, have implemented systems that access different data sources, which sometimes results in a multiplicity of databases that are difficult to sync and operate. In this context, a flexible data model is proposed that supports the modules of an integrated information system where the different management processes interact, and which allows the generation of information to help decision-making and improve the actions of the organization. Keywords: BDD (database); ERM (Entity Relationship Model); data modeling. 1.Introducción El modelamiento de los datos es una técnica que fue perfeccionándose desde los años 70, para responder a las necesidades de información, especialmente en ese entonces de los contextos productivos, bancarios y de investigación de las fuerzas armadas (Coronel, 2011). Estos roles facilitan la asignación y aprobación de permisos concedidos sobre los comandos SQL DML (Data Manipulation Language) (S=select, I=insert, D=delete, U=update, G=grant, RV=revoke).
