Methods and Tools for Automation of Development of Information Systems Using Specifications of Database Applications

The approach is based upon declarative specifications of database applications (SDA). The specifications of database applications contain all the information about database structure, which is required to build a typical AIS (automated information system). The information is represented in its pure form, so the specifications are rather concise. The AIS'es are implemented using general algorithms, which are directed by the specifications. We have developed algorithms for such tasks as: user interface generation, query building, report generation, GIS interaction. Using the specifications of database applications and the algorithms the software system GeoARM was implemented. The technology considered was well-tried by use of the system GeoARM for development of several dozens of true-life AIS for different purposes.
