Web-based concurrent design using a distributed system and database modeling approach

In this research, systems, libraries, and databases for modeling different product development life-cycle aspects are distributed at different locations that are linked through the Web. Product modeling libraries and databases at different places, described by class features and instance features, are associated by defining their relations. Product modeling systems at different locations for manipulating different product development life-cycle activities are integrated by using the system components at one location as the components at other locations.
