A Data Integration System Managed by Users

Abstract. A data integration system is a system providing a general interface to row of distributed and heterogeneous information systems. The article proposes an architecture of a data integration system based on Semantically Complete Model with the following distinctions from existent integration approaches: a) the global schema is represented as a flat concept space being transparent for users; b) creation of GUI view points, including query writing, can be fulfilled without involving IT people; c) new local schemas and view points upon them are shared automatically among all users as soon as created, administration is not necessary; d) the semantic browsing feature is supported automatically, without any programming; e) view points functionality is based on functionality of visual components (grids, charts, trees, graphs, reports, and others), which can be supplied for the system by independent software producers; f) master-detail dependencies within view points are defined in the declarative way
