Abstract

A computer program product tangibly embodied on a computer-readable medium includes executable code that, when executed, causes at least one computer system hosting a computer application to provide a memory to store results of multiple queries processed by the computer application and a feeder component in a front end display logic layer of the computer application. The feeder component is configured to read the results of the multiple queries stored in the memory asynchronously and to supply the results of the multiple queries in parallel to respective query result display entities in a user interface of the computer application.

Claims

1. A computer program product tangibly embodied on a computer-readable medium and including executable code that, when executed, is configured to cause at least one computer system hosting a computer application to provide:

a memory to store results of multiple queries processed by the computer application; and

a feeder component in a front end display logic layer of the computer application,

wherein the feeder component is configured to read the results of the multiple queries stored in the memory asynchronously and to supply the results of the multiple queries in parallel to respective query result display entities in a user interface of the computer application.

2. The computer program product of claim 1, wherein the computer application includes a back end business logic layer separate from the front end display logic layer, and wherein both the back end business logic layer and the front end display logic layer have access via a service to the memory storing the results of multiple queries.

3. The computer program product of claim 1, wherein the feeder component is configured to supply data to a particular query result display entity in the user interface of the computer application as soon as data for that particular query result display entity becomes available in the memory.

4. The computer program product of claim 1, wherein the feeder component in the front end display logic layer of the computer application is implemented as a custom feeder class.

5. The computer program product of claim 4, wherein the at least one computer system hosting the computer application is an ABAP system, and wherein the custom feeder class is an ABAP Object Oriented class.

6. The computer program product of claim 5, wherein the custom feeder class inherits one or more functions from a standard ABAP feeder basis class.

7. The computer program product of claim 6, wherein the standard ABAP feeder basis class reads data sequentially and the custom feeder class in contrast implements logic to read data asynchronously.

8. The computer program product of claim 4, wherein the custom feeder class is coupled to a ping mechanism to help determine latency or delay in a connection to the memory.

9. The computer program product of claim 4, wherein the custom feeder class is implemented as a single class with individual instantiation for each query result display entity in the user interface of the computer application.

10. A method, comprising:

providing a shared memory to store data results of multiple queries for a computer application, the computer application having a front end layer with functionality supporting a user interface and a separate back end layer with functionality supporting query functions; and

providing a front end layer component that is configured to retrieve the data results of multiple queries from the shared memory asynchronously and to provide the retrieved data results of the multiple queries to corresponding query display components in the user interface for display in parallel.

11. The method of claim 10 further comprising providing a service to access the memory storing the data results of multiple queries from the front end layer.

12. The method of claim 10, wherein providing a front end layer component includes configuring the front end layer component to supply data to a particular query result display entity in the user interface of the computer application as soon as data for that particular query result display entity becomes available in the memory.

13. The method of claim 10, wherein providing a front end layer component includes implementing the front end layer component as a custom feeder class.

14. The method of claim 13, wherein at least one computer system hosting the computer application is an ABAP system, and wherein implementing the front end layer component as a custom feeder class includes implementing the custom feeder class as an ABAP Object Oriented class.

15. The method of claim 13, wherein implementing the front end layer component as a custom feeder class includes configuring the custom feeder class to inherit one or more functions from a standard ABAP feeder basis class.

16. The method of claim 10, wherein providing a front end layer component includes configuring the front end layer component with logic to read data asynchronously.

17. The method of claim 10, wherein providing a front end layer component includes coupling the front end layer component to a ping mechanism to help determine latency or delay in a connection to the memory.

18. The method of claim 10, wherein providing a front end layer component includes implementing the front end layer component as a single class with individual instantiation for each query result display entity in the user interface of the computer application.

19. A system comprising:

at least one processor configured to execute database queries for a computer application;

a user interface including a plurality of query display elements, each query display element configured to display data results of a respective query;

a memory configured to store data results of multiple queries for the computer application; and

a feeder class component installed in a front end of the computer application, wherein feeder class component is configured to retrieve the data results of multiple queries from the shared memory asynchronously and to provide the retrieved data results of the multiple queries to corresponding query display elements in the user interface for display in parallel.

20. The system of claim 19, wherein the feeder class component is configured to supply data to a particular query display element in the user interface of the computer application as soon as data for that particular query display element becomes available in the memory.
