Abstract

A computerized method for accessing business object data stored in a data buffer of a server computer includes providing an application program interface (API) having a function for specifying a set of paths through a business object stored as a data structure in a data buffer of a server computer. Each of the paths included in the set of paths specifies a plurality of nodes of the business object for accessing hosted data at the plurality of nodes. The method further includes receiving a set of parameters for the function of the API. The set of parameters specify the set of paths. The method further includes issuing the set of parameters to the server computer, retrieving hosted data from the plurality of nodes for each path in the set of paths; and transmitting to a client the hosted data retrieved from the plurality of nodes.

Claims

1. A computerized method for accessing coarse-grained business object data stored in a data buffer of a server computer comprising:

providing via a computer system an application program interface (API) having a function for specifying a set of paths through a business object stored as a data structure in a data buffer of a server computer, wherein each of the paths included in the set of paths specifies a plurality of nodes of the business object for accessing hosted data at the plurality of nodes;

receiving via the computer system a set of parameters for the function of the API, wherein the set of parameters specify the set of paths;

issuing via the computer system the set of parameters to the server computer;

retrieving via the computer system hosted data from the plurality of nodes for each path in the set of paths; and

transmitting via the computer system to a client the hosted data retrieved from the plurality of nodes.

2. The method of claim 1, further comprising presenting via the computer system on the client the hosted data according to a tree structure specified by the set of paths.

3. The method of claim 1, wherein the retrieving step includes parsing via the computers system the set of parameters for each path.

4. The method of claim 3, wherein the retrieving step includes traversing each path in the set of paths for the business object stored in the data buffer.

5. The method of claim 1, wherein the set of parameters includes a first parameter for specifying a level of an instance in the business object and an association from the instance to a sub-node of the instance.

6. The method of claim 5, wherein the association is a name of the sub-node or a modeled or implemented relationship to the sub-node.

7. The method of claim 6, wherein the set of parameters includes a name for the instance from which the association specifies the sub-node of the instance.

8. A non-transitory computer readable medium comprises a computer program product, which includes steps for retrieving coarse-grained data for a computerized method including:

providing via a computer system an application program interface (API) having a function for specifying a set of paths through a business object stored as a data structure in a data buffer of a server computer, wherein each of the paths included in the set of paths specifies a plurality of nodes of the business object for accessing hosted data at the plurality of nodes;

receiving via the computer system a set of parameters for the function of the API, wherein the set of parameters specify the set of paths;

issuing via the computer system the set of parameters to the server computer;

retrieving via the computer system hosted data from the plurality of nodes for each path in the set of paths; and

transmitting via the computer system to a client the hosted data retrieved from the plurality of nodes.

9. The computer readable medium of claim 8, wherein the computer program product further comprises presenting via the computer system on the client the hosted data according to a tree structure specified by the set of paths.

10. The computer readable medium of claim 9, wherein the retrieving step includes parsing via the computers system the set of parameters for each path.

11. The computer readable medium of claim 10, wherein the retrieving step includes traversing each path in the set of paths for the business object stored in the data buffer.

12. The computer readable medium of claim 11, wherein the set of parameters includes a first parameter for specifying a level of an instance in the business object and an association from the instance to a sub-node of the instance.

13. The computer readable medium of claim 12, wherein the association is a name of the sub-node or a modeled or implemented relationship to the sub-node.

14. The computer readable medium of claim 13, wherein the set of parameters includes a name for the instance from which the association specifies the sub-node of the instance.

15. The computer readable medium of claim 13, wherein the set of parameters includes a first parameter for specifying a level of an instance in the business object and a set of associations from the instance to set of sub-nodes of the instance.

16. A computer system configured for accessing retrieving coarse-grained data business object data stored in a data buffer of a server computer comprising:

a set of processors configured to execute computer code; and

a set of memories respectively coupled to the set of processors and configured to store computer code and transfer the computer code to the set of processors for execution, wherein the computer code includes;

computer code for providing via a computer system an application program interface (API) having a function for specifying a set of paths through a business object stored as a data structure in a data buffer of a server computer, wherein each of the paths included in the set of paths specifies a plurality of nodes of the business object for accessing hosted data at the plurality of nodes;

computer code for receiving via the computer system a set of parameters for the function of the API, wherein the set of parameters specify the set of paths;

computer code for issuing via the computer system the set of parameters to the server computer;

computer code for retrieving via the computer system hosted data from the plurality of nodes for each path in the set of paths; and

computer code for transmitting via the computer system to a client the hosted data retrieved from the plurality of nodes.

17. The computer system of claim 16, wherein the computer code further includes computer code for presenting via the computer system on the client the hosted data according to a tree structure specified by the set of paths.

18. The computer system of claim 17, wherein the retrieving step includes parsing via the computers system the set of parameters for each path.

19. The computer system of claim 18, wherein the retrieving step includes traversing each path in the set of paths for the business object stored in the data buffer.

20. The computer system of claim 19, wherein the set of parameters includes a first parameter for specifying a level of an instance in the business object and an association from the instance to a sub-node of the instance.
