The Multi-Meta Database Model as a Foundation for Schema Reuse in Conceptual Database Design

We are proposing a multi-meta model that serves as afoundation for schema reuse in conceptual database design. Multimetamodel is based on entity-relationship model. According to theproposed model corresponding database, called multi-meta databaseis built. Multi-meta database contains descriptions of the existingdatabase models and serves as a basis for design of new models. Toavoid ambiguity regarding the model descriptions the redundancy hasbeen maximally reduced without loss of any existing knowledge. Theprocess of the design of a new database model can cause therestructuring of existing knowledge contained in the multi-metadatabase. In the proposed non-redundant model the restructuring issimplified, while the consistencies are preserved. The necessaryconditions that have to be satisfied by each database model aredefined. In case that these conditions are not met, the describedprocedures for the model restructuring have to be applied.
