Abstract

Managing data stewardship in multi-level MDM systems may include a steward data composer that creates data steward repository for a master data management system to define relationships between data stewards and data objects for which data stewards are responsible and steward data consolidator that creates an integrated data steward repository by combining multiple data steward repositories.

Claims

1. A system for managing data stewardship in a multi-level master data management system, comprising:

steward data composer including at least;

steward data creator operable to create a data steward repository for a master data management system to define relationships between data stewards and data objects for which data stewards are responsible;

steward data consolidator operable to create an integrated data steward repository by combining multiple data steward repositories; and

steward data conflict resolver operable to support functionality that overrides data steward relationships; and

data stewardship facilitator including at least;

data steward locator operable to determine from the data steward repository the data steward responsible for a data object;

data update notification module operable to notify the determined data steward of a pending data update; and

data update handler operable to support data steward to approve or reject the data update,

wherein the multi-level master data management system comprises a plurality of master data management systems and each of the plurality of master data management systems comprises the steward data composer and the data stewardship facilitator.

2. The system of claim 1, wherein the plurality of master data management systems includes a group master data management node and a plurality of participant master data management nodes.

3. The system of claim 2, wherein the steward data consolidator integrates the defined relationships of the participant master data management nodes to a data steward repository of the group master data management node.

4. The system of claim 2, wherein the plurality of master data management systems further includes a root master data management node comprising a plurality of group master data management nodes.

5. The system of claim 4, wherein the steward data consolidator integrates data in the data steward repository of the group master data management node to a data steward repository of the root master data management node.

6. The system of claim 1, wherein the steward data conflict resolver resolves conflict existing in the defined relationship between two master data management nodes that are linked by an operational link and in which at least one of the two master data management nodes is implemented in transaction style.

7. A method of managing data stewardship in multi-level master data management system, the multi-level master data management system including a plurality of participant master data management nodes and a group master data management node that manages the plurality of participant master data management nodes, comprising:

creating a data steward repository for each of the participant master data management nodes to define relationships between data stewards and data objects for which data stewards are responsible;

determining a data access link type between each of the participant master data management nodes and the group master data management node;

integrating data steward information of a participant master data management node of the plurality of participant master data management nodes to a data steward repository of the group master data management node, in response to determining that data access link type between the participant master data management node and the group master data management node is a reference link; and

in response to determining that a data access link type between the participant master data management node and the group master data management node is an operational link, performing a conflict check and resolution for existing conflict before integrating data steward information of the participant master data management node to the group master data management node,

wherein the multi-level master data management system comprises a plurality of group master data management nodes, each managing a plurality of participant master data management nodes, and wherein the method further comprises creating a data steward repository of a root master data management node that manages the plurality of the group master data management nodes by integrating data steward information of the plurality of the group master data management nodes to the data steward repository of the root master data management node.

8. The method of claim 7, wherein in response to receiving a request for update of data, the group master data management node searches and identifies from the group master data management node'"'"'s data steward repository, a data steward responsible for the data.

9. The method of claim 8, wherein the group master data management node sends a notification to the identified data steward.

10. The method of claim 8, wherein a user interface is provided to the identified data steward to support the identified data steward in updating of the data.

11. The method of claim 7, further including:

in response to a request to disconnect a participant master data management node from the multi-level master data management system, removing data steward information associated with the disconnecting master data management node from the group master data management node'"'"'s data steward repository.

12. A computer readable storage medium storing a program of instructions executable by a machine to perform a method of managing data stewardship in multi-level master data management system, the multi-level master data management system including a plurality of participant master data management nodes and a group master data management node that manages the plurality of participant master data management nodes, comprising:

creating a data steward repository for each of the participant master data management nodes to define relationships between data stewards and data objects for which data stewards are responsible;

determining a data access link type between each of the participant master data management nodes and the group master data management node;

integrating data steward information of a participant master data management node of the plurality of participant master data management nodes to a data steward repository of the group master data management node, in response to determining that data access link type between the participant master data management node and the group master data management node is a reference link; and

in response to determining that a data access link type between the participant master data management node and the group master data management node is an operational link, performing a conflict check and resolution for existing conflict before integrating data steward information of the participant master data management node to the group master data management node,

wherein the multi-level master data management system comprises a plurality of group master data management nodes, each managing a plurality of participant master data management nodes, and wherein the method further comprises creating a data steward repository of a root master data management node that manages the plurality of the group master data management nodes by integrating data steward information of the plurality of the group master data management nodes to the data steward repository of the root master data management node.

13. The computer readable storage medium of claim 12, wherein in response to receiving a request for update of data, the group master data management node searches and identifies from the group master data management node'"'"'s data steward repository, a data steward responsible for the data.

14. The computer readable storage medium of claim 13, wherein the group master data management node sends a notification to the identified data steward.

15. The computer readable storage medium of claim 13, wherein a user interface is provided to the identified data steward to support the identified data steward in updating of the data.

16. The computer readable storage medium of claim 12, further including:

in response to a request to disconnect a participant master data management node from the multi-level master data management system, removing data steward information associated with the disconnecting master data management node from the group master data management node'"'"'s data steward repository.
