Аннотация: We consider the approach to development of AIS (automated information system) using 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. 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. In this article we’ll describe the approach, that we use for creation of several versions of the GeoARM engine, which use different data access libraries, from the common source code base. The resulting versions of the GeoARM engine allow us to create problem-oriented AIS’es for all the supported platforms from the single SDA.
