Asso: a formal database design methodology

The main aspects of ASSO, a formal database design methodology, are introduced. ASSO integrates typical database features within the B-Method, a formal method from the software engineering area. As a result, ASSO guarantees design correctness while enabling the application requirements to be specified with the flexibility of semantic data models and ensuring that the efficiency of objectoriented implementations in terms of storage structures and object management can be obtained.
