--- res: bibo_abstract: - The paper presents an approach to specify in an integrated way by visual, diagrammatic languages the structural and behavioural aspects of database applications. Hereby, well-known extended Entity-Relationship diagrams are employed to specify the structural aspects. The behavioural aspects of a database application are specified by using ViAL (Visual Action Language). ViAL specifications are a special kind of data (or better object) flow diagrams, where so-called elementary actions are used as basic building blocks. These elementary actions are automatically derived from a given EER diagram. They guarantee that after finishing their execution all inherent integrity constraints are fulfilled. The paper explains the features of the language ViAL and gives some illustrating examples.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Gregor foaf_name: Engels, Gregor foaf_surname: Engels foaf_workInfoHomepage: http://www.librecat.org/personId=107 - foaf_Person: foaf_givenName: Perdita foaf_name: Löhr, Perdita foaf_surname: Löhr dct_date: 1994^xs_gYear dct_language: eng dct_publisher: Springer@ dct_title: Visual Specification of Complex Database Actions@ ...
