Appl. No.:

8/769042

Inventors:

Tom Chase - Ann Arbor MI
Chuck Weingart - Livonia MI

Chrysler Corporation - Auburn Hills MI

International Classification:

G06F 1730

US Classification:

707102

Abstract:

Information is extracted from a redevelopment database having relational information for software programs or files, and placed in files which are subsequently used with user provided parameters, entered through a user interface, by a partitioner. The partitioner uses a two stage process to grow a partition, beginning with the first stage which involves addition and deletion of programs and files from the partition based upon a score which represents the importance of the number of connections that a program or file has in the partition and the number of connections a program or file has in the partition in relation to the programs or files total number of connections. Once a partition with a minimum number of programs or files has been reached, stage two is executed. Stage 2 continues to grow the partition until a partition with a maximum number of programs or files has been reached. This is accomplished by first adding those programs or files which have a specified percentage of their connections in the stage 1 generated partition.

Abstract:

A predetermined change to a software system having a large number of highly connected and interrelated executables and data files is accomplished using a redevelopment database which is generated from a software library. The redevelopment database maintain resource and relational information on the executables and data files. This information is used by a partitioner which creates groups of executables and data files which have minimal connections to executables and data files outside a given group. The groups are assigned to a resource, with the resource performing the software changes in a given group with the aid of software change mechanisms. After the changes in a group are completed, a configuration management system of the software system receives the newly modified software, updating the software system. The configuration management system also notifies the redevelopment database so that the relational and resource information of the redevelopment database remains up to date, and continues to support the day-to-day modifications other than the predetermined software change.
