AN EMF ECORE BASED RELATIONAL DB SCHEMA META-MODEL.

In the paper we focus on models related to databases. For these models we use a generic name database models. They may be created at several, usually different levels of abstraction. In this paper, we propose a classification of database models and meta-models. Also, we present a meta-model of relational database schema specified by means of the Eclipse Modeling Framework (EMF) and based on the EMF Ecore meta-meta-model which is closely aligned with the Essential MOF (EMOF) specification.
