Abstract

Problems which arise up during work with separate information sources and databases are analyzed. There are formalized model of data space as mean of integration and information analysis from separate sources. There is built data space algebraic system. It is shown that the algebraic system of database and data warehouse classes is the subclasses of the data space class algebraic system. The features of information integration are certain from heterogeneous sources. The chart of information integration and facilities of data exchange is built. The data completeness and usefulness of accumulated decisions are affecting the quality of the data space.

 

Key words: Data space, data warehouse, integration methods, consolidation, information product.
