Abstract

A Data Management System has a plurality of data managers and is of a layered architecture. The system performs with a data manager and with a user input via an API a plurality of process on data residing in heterogeneous data repositories of said computer system including promotion, check-in, check-out, locking, library searching, setting and viewing process results, tracking aggregations, and managing parts, releases and problem fix data under management control of a virtual control repository having one or more physical heterogeneous repositories. The system provides for storing, accessing, tracking data residing in said one or more data repositories managed by the virtual control repository. User Interfaces provide a combination of command line, scripts, GUI, Menu, Web Browser, and other interactive means which maps the user'"'"'s view to a PFVL paradigm. Configurable Managers include a query control repository for existence of peer managers and provide logic switches to dynamically interact with peers. A control repository access layer provides a common process interface across all managers, which utilizes a virtual table paradigm to standardize communication with the control repository. Command translators map the generic control repository accesses into the appropriate format for interfacing with the underlying physical embodiment of the control repository.

Claims

1. A method for a data management system having a plurality of data managers, comprising the steps of:

providing said plurality of data managers in one or more layers of a layered architecture, and

performing with a data manager and with a user input via an API a plurality of processes on data residing in heterogeneous data repositories of said computer system including promotion, check-in, check-out, locking, library searching, setting and viewing process results, tracking aggregations, and managing parts, releases and problem fix data under management control of a virtual control repository having one or more physical heterogeneous repositories, and

storing, accessing, tracking data residing in said one or more data repositories managed by said virtual control repository, and

wherein said virtual control repository comprises virtual tables and all virtual control repository access functions are implemented as transactions constructed using a generic structure, and

command translators are employed to map generic virtual control repository transactions into any required command interface needed to interact with the corresponding physical implementation of said virtual control repository, wherein control repository access transactions use a generic structure to invoke one or a plurality of command translators to interact with one or more physical control repositories.

2. The method according to claim 1 wherein any number of command translators can be employed to map one or more generic control repository access transactions into one or more physical control repository operations.

3. The method according to claim 1 wherein said command translators may exist as physical entities separate from the control repository access transactions, and said physical entities separate from the control repository access transactions may be embedded within said transactions as one or more subroutines, functions, objects and modules.
