Filed:

Sep 15, 2004

Appl. No.:

10/941618

Inventors:

Neeraj Sangal - Andover MA, US
Everette T. Jordan - Needham MA, US
Francis A. Waldman - Stoneham MA, US
Carl D. Parisi - Chelmsford MA, US

Assignee:

Lattix Inc. - Andover MA

International Classification:

G06F 9/44

US Classification:

717100

Abstract:

A method and apparatus for managing, in a computer system, design of a software system. Various embodiments include receiving an input to the computer system specifying dependency relationships among subsystems of the software system and providing an output from the computer system responsive to the input. A rule is imposed on at least one of the dependency relationships and data for the rule is provided as part of the input.

International Classification:

G06F 17/30

US Classification:

707970, 707797, 707829

Abstract:

A method is provided for managing, in a computer system, design of a database system having a set of schemata. The method includes, in a first computer process, extracting dependencies from the database system and identifying the set of schemata. The method further includes, for each specific schema in the set of schemata, creating in a second computer process a partition that, in turn, contains a further partition for each element of the specific schema, so as to establish a hierarchy of partitions in accordance with the structure of the set of schemata. The method also includes storing a representation of the database system including subsystems, dependency relationships among the subsystems, and the hierarchy of partitions. Finally, the method includes providing a graphical output from the computer system, based on the stored representation, in which appears a display of the subsystems in a hierarchy of partitions within a dependency structure matrix, such matrix graphically indicating the dependency relationships among subsystems. Related apparatus and computer products are also provided.
