PDM systems provide you with the robust feature of controlling the changes to the files. Each time a file is modified, a new version is created, and you can track changes over time. This ensures that the history of changes to each design file is ideally maintained.
Check-In and Check-Out
PDM is extensively preferred for the check-in and check-out mechanisms. When you or any other user checks out a file for editing, it is temporarily locked, preventing others from making any conflicting changes. After editing, the user checks the file back in, creating a new version.
Every change made to the design file can be easily tracked. Users can easily identify the differences between every revision, providing a detailed view of the design evolution.
