A method, system and computer product for a Smart-Bricks Information System (IS), which solves the problems of lack of adaptability and lack of flexibility of information systems. In order to provide adaptability and flexibility of the IS, the enterprise's information space is divided into a plurality of universal micro-blocks—Smart-Bricks micro-systems. The Smart-Bricks IS implements the following: contains all necessary and sufficient system parts for the functioning of each micro-system (data, code, interface); self-assembles into “instantaneous info-conglomerates”-Smart-Bricks Instant Performances (SBIP); and runs under control of the Ontological Model of an enterprise subject area, which is adaptable to the changing conditions of a given subject area.
