Abstract:
Many problems of traditional business systems (SAP, Microsoft Dynamics, etc.) are largely caused by their architecture where a tier that implements the business model and data processing (application server or thick client) is separated from the DBMS where the data is stored. A new approach to extend the relational DBMS with a means for creating expressive heterogeneous business models according to principles well-known to users of existing business systems is discussed. With it the business system architecture can be simplified fundamentally because of transferring all data modelling and processing directly to the place of their storage. Principles of a creation and a use of complex business models and data access in these models are discussed. Some questions related to system performance are reviewed.
