Abstract

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 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.

7. A data management system for file and database management according to claim 6 wherein said library manager employs a plurality of automated library machines to act as independent agents servicing a user community, and said library manager organizes said automated library machines as service machines which use a virtual queue to accept work requests from users and perform Library and non-Library functions, said automated library machines interfacing with said data control repository to store data resulting from said processing in said control repository.

8. A data management system for file and database management according to claim 7 wherein one of said managers of said database management system is a communication manager, and said library manager providing via said communication manager interfaces for said automated library machines interfacing directly with the data control repository through dedicated high speed ports in the communication manager.

9. A data management control program according to claim 7 wherein queued work is prioritized using a class system whereby there exists one or more classes such that work in the highest order class is processed before work in the next lower class, and so on until work in the lowest order class is processed.

10. A data management system for file and database management according to claim 6 wherein said automated library machines are servers which can exist on clients, servers and on different computer platforms with a configuration allowing (1) a single automated library machine to accept all work requests and handle all services for the library manager including any automated library processing, (2) a plurality of remote execution machines wherein a single master automated library machine receives all work requests from the user, and processes all promotion, installation, movement, and removal of data while others of said plural automated library machines perform automated library processing and interact with the library manager, communication manager and where any desired library processing is dispatched to a remote execution machine which executes the tasks and returns the results to the master automated library machines, and (3) a pool general purpose machines enabled for performing any desired management functions, including automated library processing, as Actor/Objects which have in turn an interface with remote execution machines for providing an environment with both general purpose machines and dedicated service machines, whereby each general purpose machine is programmed to define the type of work it can process, including the work of a dispatcher which dispatches user work requests to the next available Actor machine.

11. A data management control program according to claim 10 wherein a Dispatcher will rank order queued work based first on a class system and secondly on First-In-First-Out treatment of work within a class, and provide a library monitor utility (LIBMON) to permit queued work to be reprioritized or deleted by the Data Manager.

12. A data management system for file and database management according to claim 6 wherein said automated library machines are special purpose autoreader service machines having means for performing work entered from a command line independently of said data management control system, enabling said automated library machines to perform a data management request and thereafter a different function, such as a formatting a word processing document for printing the next minute.
