Abstract

A method, system and computer program product for managing distributed data is presented. A first datum, which is represented in an upper tier of a data tree, is received from a client computer by a first upper tier partition server. The first upper tier partition server is part of a plurality of upper tier partitions servers. A partition server manager in the first upper tier partition server identifies at least one other upper tier partition server that contains an other datum from the upper tier of the data tree. The at least one other upper tier partition server is registered with the client, such that the client is able to manage other upper tier data stored in the plurality of other upper tier partition servers.

Claims

identifying, by a partition server manager in the first upper tier partition server, at least one other upper tier partition server that contains an other datum from the upper tier of the data tree, wherein the at least one other upper tier partition server is from the plurality of upper tier partition servers; and

registering the at least one other upper tier partition server with the client, wherein the client is able to directly manage other upper tier data stored in the plurality of other upper tier partition servers.

2. The computer-implemented method of claim 1, further comprising:

locating, by a data relation manager in one of the plurality of upper tier partition servers, at least one lower tier partition server, wherein the at least one lower tier partition server contains only data from a lower tier of the data tree; and

registering the at least one lower tier partition server with the client, wherein the client is able to identify and locate datum, from the lower tier of the data tree, that is related to the first datum from the upper tier of the data tree.

3. The computer-implemented method of claim 2, further comprising:

automatically refreshing data from the plurality of upper tier partition servers and the plurality of lower tier partition servers to the client, wherein automatic refreshing is performed by a duration and interval manager that is executed by one or more of the plurality of upper tier partition servers.

4. The computer-implemented method of claim 1, further comprising:

utilizing a depth manager, in one of the plurality of upper tier partition servers, to control client access to subsequently lower tiers of the data tree.

5. The computer-implemented method of claim 1, further comprising:

deregistering and decoupling the client from the plurality of upper tier partition servers, wherein the deregistering and decoupling are performed by a deregistration and decoupling mechanism that is executed by one or more of the plurality of upper tier partition servers.

6. The computer-implemented method of claim 1, wherein the upper tier of the data tree is subordinate to an apex node in the data tree, and wherein the partition server manager identifies the at least one other upper tier partition server by locating other upper tier datum that is also subordinate to the apex node in the data tree.

7. A system comprising:

a processor;

a data bus coupled to the processor;

a memory coupled to the data bus; and

a computer-usable medium embodying computer program code, the computer program code comprising instructions executable by the processor and configured for managing distributed data by;

receiving a first datum from a client computer, wherein the first datum is represented in an upper tier of a data tree, and wherein the first datum is received by a first upper tier partition server that is part of a plurality of upper tier partitions servers;

identifying, by a partition server manager in the first upper tier partition server, at least one other upper tier partition server that contains an other datum from the upper tier of the data tree, wherein the at least one other upper tier partition server is from the plurality of upper tier partition servers; and

registering the at least one other upper tier partition server with the client, wherein the client is able to manage other upper tier data stored in the plurality of other upper tier partition servers.

8. The system of claim 7, wherein the instructions are further configured for:

locating, by a data relation manager in one of the plurality of upper tier partition servers, at least one lower tier partition server, wherein the at least one lower tier partition server contains only data from a lower tier of the data tree; and

registering the at least one lower tier partition server with the client, wherein the client is able to identify and locate datum, from the lower tier of the data tree, that is related to the first datum from the upper tier of the data tree.

9. The system of claim 8, wherein the instructions are further configured for:

automatically refreshing data from the plurality of upper tier partition servers and the plurality of lower tier partition servers to the client, wherein automatic refreshing is performed by a duration and interval manager that is executed by one or more of the plurality of upper tier partition servers.

10. The system of claim 7, wherein the instructions are further configured for:

utilizing a depth manager, in one of the plurality of upper tier partition servers, to control client access to subsequently lower tiers of the data tree.

11. The system of claim 7, wherein the instructions are further configured for:
