Abstract

A data management system for file and database management including a design control system suitable for use in connection with the design of integrated circuits and other elements of manufacture having many parts which need to be developed in a concurrent engineering environment with inputs provided by users and or systems which may be located anywhere in the world providing a set of control information for coordinating movement of the design information through development and to release while providing dynamic tracking of the status of elements of the bills of materials in an integrated and coordinated activity control system utilizing a control repository which can be implemented in the form of a database (relational, object oriented, etc.) or using a flat file system. Once a model is created and/or identified by control information design libraries hold the actual pieces of the design under control of the system without limit to the number of libraries, and providing for tracking and hierarchical designs which are allowed to traverse through multiple libraries. Data Managers become part of the design team, and libraries are programmable to meet the needs of the design group they service. A control repository communicates with users of the design control system for fulfilling requests of a user and with data repositories of said data management control system through a plurality of managers. Each manager performs a unique function. Managers act as building blocks which can be combined in a plurality of manners to support an environment for suitable for multiple users of a user community.

8. A data management system according to claim 1 wherein said tasks of the user'"'"'s data manager include

defining the relationships and dependencies between multiple Library Processes which exist at the same Version, Level and File Type within a given Library.

9. A data management system according to claim 7 wherein said tasks of the user'"'"'s data manager include

using Process Groups to install one or more previously defined Library Processes defined by said creating or copying Automated Library Process Definitions without the need to manually enter all the required information, and

wherein these process groups also permit the Data Manager to install the same Library Processes across multiple libraries in an identical fashion.

10. A data management system according to claim 1 wherein said tasks of the user'"'"'s data manager include

defining one or more Automated Library Machines to perform work for said Library, including the type of Automated Library Machine and various workload balancing and monitoring facilities to aid in distribution and assignment of jobs across the library enterprise.

11. A data management system according to claim 1 wherein said tasks of the user'"'"'s data manager include

creating one or more reports to query and display the multitude of characteristics and properties defined within a Library, including Versions, Levels, file types, Authorities, Library Processes, Automated File Groups, Library Process Definitions, and Package Control Data.

12. A data management system according to claim 1 wherein said tasks of the user'"'"'s data manager include
