In enterprise grade applications and specifically in product data management, the main focus of PLM vendors was about how to manage CAD files and optimizing check-in/check-out process , managing BoM , process control and measurement. This was mainly driven by the scientific discipline of “Knowledge management” (This term appeared in early 1990s) which was to use software to manage knowledge base , decision support systems and other joined efforts. But most PLM systems failed to deliver anything beyond data records which are yet to be discovered, analyzed and connected.
