System and method for managing and updating data from a number of sources for a project

Abstract

The disclosure relates to a system and method for managing data from a number of systems. The method comprises: defining a set of objects for the data; defining a set of classes for the data; maintaining a catalog for each instance of the data; in the catalog identifying each instance's source system and its level of harmonization with other data; applying a set of harmonization rules to identify from the data a group of related data and an owner of the group; identifying differences in instantiations within the group; and initiating update requests to affected systems having the identified differences.

1 . A method for managing data provided from a plurality of systems, comprising:
 providing a set of objects for data;   providing a set of classes for the data;   maintaining a catalog with an entry for each data instance of the data;   in the catalog, identifying for each data instance its source system and its level of harmonization with other data from the plurality of systems;   applying a set of harmonization rules to the data to identify a group of related data and an owner of the group of data;   identifying differences in instantiations in the group of data; and   initiating an update request to an affected system of the plurality of systems having the differences,   wherein the data is accessible by a central data processing system which stores a copy of the data and selectively initiates the update requests.
