Development of SDAI-based common access interface for object-oriented DBMS

The objective of this research is to construct a data access implementation at the database level using the specifications defined in the ISO 10303 St andard Data Access Interface (SDAI). This paper documents the process of im plementing the SDAI on a specific object-oriented database management syste m (OODBMS), called Web-based Object Oriented-DataBase (WOO-DB). WOO-DB is d eveloped by the Institute for Information Industry and uses a proprietary o bject definition language (ODL) and object manipulation language (OML) to d escribe and manipulate data. The implementation is achieved by mapping the functions and schemata between the SDAI data model and WOO-DB ODL and OML. This research concludes a number of basic features that an OODBMS should su pport when constructing the SDAI access mechanism. Once the data access int erface is independent of data storage technologies, the integration of appl ications in a computer-aided Concurrent Engineering environment can be achi eved under a common data accessing protocol.
