1. A data management control system for managing a plurality of projects as a design control system, comprising: for each project a control repository and one or more data repositories to store, manage, and manipulate any data object, wherein said control repository communicates with users and the data repositories in numerous ways to support environments ranging from a small user community to a global enterprise with all data and control information tracked in an architecturally centralized environment consisting of said data repository and said control repository using a single logical PFVL paradigm to identify all data in the DMS by Package, File Type, (Data Type), Version and Level, and wherein packages are arbitrary divisions of data, whereby all the data has some common association and wherein every piece of the design which is associated to a Library - Variance - Quality Level - View - Cell - Version has all of the data associated as a logical union so that the system ensures every piece of data has all said PFVL attributes associated with said every piece of said data as a PFVL single logical association, permitting every piece of data or attribute of a design element in the Data Management System (DMS), regardless of origin or importance, to be tracked by its PFVL single logical association of every piece of the design.
