The Multi-Meta Model Aimed for Schema Reuse in Conceptual Database Design

In this article a database model, called multi-meta model, aimed for schema reuse in conceptual database design is described. The multi-meta model is based on the entity-relationship model. The corresponding multi-meta database contains the description of existing database models. In the description of models contained in the multi-meta base, the redundancy has been maximally reduced without loss of existing knowledge. In this way, any ambiguity regarding the model description has been eliminated. The restructuring of knowledge about models is simplified, while the model consistencies are preserved. The necessary conditions are defined that have to be satisfied by each database model. If these conditions are not met, the described procedures for the model restructuring have to be applied.
