Existing automated information systems are expensive and cannot meet the needs of enterprises manufacturing high-technology equipment. The individual CAD (computer-aided design), CAM (computer-aided manufacturing), CAE (computer-aided engineering), PDM (product data management), FRP (finance requirements planning), MRP (material requirements planning), MRPII (manufacturing resource planning) and MES (management execution systems) systems are intended for local automation and the formation of traditional databases. They do not permit the creation of a unified information space, capable of synchronized data exchange between different components within the product lifecycle.
