Vadim Ermolayev, Natalya G. Keberle · 2000
Database applications are subjected to numerous changes within their life cycle. Traditional methods and tools for design and implementation of information systems do not possess the means flexible enough to robustly face these changes. The paper presents a method and a tool for the design of flexible and, therefore, easily maintained database applications. The method is based upon a modified IS design procedure assuming data model to be active control part of the application. Data Dictionary discussed is supplied with active control elements and is a program media for data model to serve as information system control engine. Introduced is the concept and the prototype of active data dictionary as well as some extensions to classical relational data model.
