A newcomer to the engineering data management marketplace might quickly come to the conclusion there are two options if wanting to upgrade from Windows Explorer as a management tool. The first is to buy a system that helps engineers in a workgroup manage design files (PDM); the second is to buy a specialized database (PLM) that breaks down all information—CAD data and everything else—and stores it separately from the familiar files/folders structure. For many businesses looking to upgrade their engineering automation, the first option is too limiting and the second is too massive.
The traditional PDM (Product Data Management) approach is to make the CAD document the center of the universe. The PDM software manages sets of linked files for version control, synchronized check-in/check-out, and controls access right. The PLM (Product Lifecycle Management) approach requires the enterprise to import all data (CAD and from every other electronic document used in engineering) into a relational database, and then to adopt new workflows based on the design of the PLM system.
