Abstract

According to one embodiment of the present invention, a system selects member objects from among data objects stored in one or more data sources by evaluating criteria against information about the data objects in an index, wherein the information about the data objects in the index is derived from the data sources. The system creates a set of data objects comprising a collection of references to the selected member objects, and associates the set with a set-identifier. The system receives a request to apply an action to a subset of the data objects stored in the one or more data sources, wherein the request specifies the subset by including the set-identifier, and applies the action to the set of data objects associated with the set-identifier within the request. Embodiments of the present invention further include methods and computer program-products for managing data in substantially the same manners described above.

Claims

1. A computer-implemented method of managing data using a set of data objects comprising:

generating an index including information about data objects stored in one or more data server systems comprising different types of indexed data repositories by accessing individual indexes associated with each of the one or more data server systems via adapters, wherein, in generating the index, the data objects stored in the data server systems remain intact and are not replicated;

selecting member objects from among the data objects stored in the one or more data server systems by evaluating criteria against the information in the generated index, wherein the information in the generated index is derived from the one or more data server systems;

creating an information set comprising an identifier of a parent information set and a collection of references to the member objects selected subsequent to the generating of the index by applying the criteria to candidates belonging to the parent information set and tagging the information in the generated index that is associated with the selected member objects with a set-identifier when the criteria are satisfied;

associating the information set with the set-identifier;

receiving a request to apply an action to a subset of the data objects stored in the one or more data server systems, wherein the request specifies the subset by including the set-identifier; and

applying the action to the selected member objects referenced by the collection of references associated with the set-identifier within the request.

2. The computer-implemented method of claim 1, wherein the generated index includes an object-identifier for each of the data objects, and the references to the selected member objects comprise object-identifiers for the selected member objects.

3. The computer-implemented method of claim 1, wherein the generated index and the collection of references are immutable, such that the information set includes a representation of the criteria and the information in the generated index from when the collection of references was created.

4. The computer-implemented method of claim 1, wherein a set operation is performed on the information set and a second information set to create a third information set.

5. The computer-implemented method of claim 1, wherein the one or more data server systems comprise a plurality of distributed data server systems of different types.

6. The computer-implemented method of claim 1, wherein the information set further comprises one or more exceptions resulting from applying the action.

7. A system for managing data using a set of data objects comprising:

a computer system including at least one processor configured to;

generate an index including information about data objects stored in one or more data server systems comprising different types of indexed data repositories by accessing individual indexes associated with each of the one or more data server systems via adapters, wherein, in generating the index, the data objects stored in the data server systems remain intact and are not replicated;

select member objects from among the data objects stored in the one or more data server systems by evaluating criteria against the information in the index, wherein the information in the index is derived from the one or more data server systems;

create an information set comprising an identifier of a parent information set and a collection of references to the member objects selected subsequent to the generating of the index by applying the criteria to candidates belonging to the parent information set and tagging the information in the generated index that is associated with the selected member objects with a set-identifier when the criteria are satisfied;

receive a request to apply an action to a subset of the data objects stored in the one or more data server systems, wherein the request specifies the subset by including the set-identifier; and

apply the action to the selected member objects referenced by the collection of references associated with the set-identifier within the request.

8. The system of claim 7, wherein the generated index includes an object-identifier for each of the data objects, and the references to the selected member objects comprise object-identifiers for the selected member objects.

9. The system of claim 7, wherein the generated index and the collection of references are immutable, such that the information set includes a representation of the criteria and the information in the generated index from when the collection of references was created.

10. The system of claim 7, wherein a set operation is performed on the information set and a second information set to create a third information set.

11. The system of claim 7, wherein the one or more data server systems comprise a plurality of distributed data server systems of different types.

12. The system of claim 7, wherein the information set further comprises one or more exceptions resulting from applying the action.

13. A computer program product for managing data using a set of data objects comprising:

a non-transitory computer readable storage medium having computer readable program code embodied therewith for execution on a processing system, the computer readable program code comprising computer readable program code configured to;

generate an index including information about data objects stored in one or more data server systems comprising different types of indexed data repositories by accessing individual indexes associated with each of the one or more data server systems via adapters, wherein, in generating the index, the data objects stored in the data server systems remain intact and are not replicated;

select member objects from among data objects stored in the one or more data server systems by evaluating criteria against the information in the index, wherein the information in the index is derived from the one or more data server systems;

creating an information set comprising an identifier of a parent information set and a collection of references to the member objects selected subsequent to the generating of the index by applying the criteria to candidates belonging to the parent information set and tagging the information in the generated index that is associated with the selected member objects with a set-identifier when the criteria are satisfied;

receive a request to apply an action to a subset of the data objects stored in the one or more data server systems, wherein the request specifies the subset by including the set-identifier; and

apply the action to the selected member objects referenced by the collection of references associated with the set-identifier within the request.

14. The computer program product of claim 13, wherein the generated index includes an object-identifier for each of the data objects, and the references to the selected member objects comprise object-identifiers for the selected member objects.

15. The computer program product of claim 13, wherein the generated index and the collection of references are immutable, such that the information set includes a representation of the criteria and the information in the generated index from when the collection of references was created.

16. The computer program product of claim 13, wherein a set operation is performed on the information set and a second information set to create a third information set.

17. The computer program product of claim 13, wherein the one or more data server systems comprise a plurality of distributed data server systems of different types.
