This paper presents an assistant database design system, ExpertDB, which is based on entity-relationship (ER) approach. The approach is to synthesize a normalized ER schema (which consists of entity set and relationship set expressions) from functional dependencies (FD). Using as input the set of attributes and FD's, we derive the minimal cover of FD's, partition and regroup FD's, and finally form the entities and relationship sets. In every aspect of these derivations, ExpertDB provides assistance to the user, which is usually the database administrator (DBA), in the database design. The resulting ER schema is then mapped to relational schema. |
