Each project has its own Component Library, GPRD Library and Calculation Defaults Library. In addition to Project (local) libraries, RAM Commander central database contains Global Libraries - Component Library, GPRD Library, Calculation Defaults Library and Cross-Reference Library. The diagram below provides illustration to the available library types and their locations:

 

Project libraries are used by one particular project (there is also an option to copy libraries from one project to another). Global libraries are used by all projects and shared between all network users (in case of client/server installation).

 

Usually all users may update project libraries, and only Administrator/Manager may review, approve and copy data from project libraries to the global library - otherwise global libraries will turn into garbage collection due to uncontrolled data input from multiple users.
