Conference proceedings 1992imilarly, those working on formal specification techniques have recognised that the database field provides a rich context for developing their ideas. However, as experts in one field often have a relatively limited knowledge of the other, there is a growing need for discussion about the relationshi

Transforming Functional Database Schemes to Relational Representations,schemes into (relational) database schemes for which efficient implementations exist and are widely available. This paper presents a precise and linear-time algorithm for transforming functional database schemes into relational ones..The functional database model has a graphical representation which

Formal Development of Relational Database Applications,hod prescribes how to capture the important aspects of a relational application, including the definition of relations, the specification of candidate and foreign keys, and querying and updating of relations, including error handling. Some features of the relational model itself are specified as pre

Formal Definition of Nested Relations by Syntactical Mappings,tions are viewed as Extended BNF, non-recursive grammars, and instances of the database as sentences generated by the grammar. Then most algebraic operators are conveniently expressed as syntax-directed translations. The method is applied to a large subset of ALGRES, an extended relational system, a
