Abstract: he importance of product data exchange and the details of the design of Model Ac-cess Software (MAS) are described.MAS uses the thought of internal data management to im-plement the main functions which were defined in SDAI standard of STEP(ISO 10303-22) It is an late-binding interface which is independent of the schema. MAS provides an standard mod-el data access interface available to the application programme.

Key words: products, data, exchanging, access contol
