Abstract

A system, method, and computer program product are provided for abstracting data in a remote data source. A method operates by defining the data source, defining a data synchronization methodology for communication with the data source, and providing an abstraction layer for accessing data in the data source. The abstraction layer implements the data synchronization methodology when data is accessed through the abstraction layer is presented.

Claims

1. A method for abstracting data in a remote data source for use by a mobile device having occasional connectivity, comprising:

defining said remote data source;

defining a data synchronization methodology for communication with said remote data source; and

providing an abstraction layer for accessing data in said remote data source, said abstraction layer implementing said data synchronization methodology when data is accessed through said abstraction layer.

2. The method of claim 1, further comprising:

defining a method by which said data is provided by said remote data source to said mobile device.

3. The method of claim 1, further comprising:

interfacing with a mobile business object (MBO).

4. The method of claim 3, further comprising:

defining security characteristics of said MBO;

defining data synchronization characteristics of said MBO; and

defining relationships between said MBO and other MBOs.

5. The method of claim 3, further comprising:

defining in-bound invocation methods for said MBO.

6. The method of claim 3, further comprising:

defining metadata for said MBO.

7. The method of claim 6, further comprising:

capturing said metadata with a modeling tool.

8. The method of claim 3, further comprising:

performing an application program interface (API) call to said MBO; and

obtaining a response to said API call, wherein said response is based on a state of said MBO.

9. A system for abstracting data in a remote data source for use by a mobile device having occasional connectivity, comprising:

a middleware associated with said remote data source; and

a mobile business object (MBO) associated with said middleware, wherein said MBO includes at least a subset of data in said remote data source.

10. The system of claim 9, further comprising:

a mobile application associated with said middleware, wherein said mobile application is configured to access data in said remote data source using an application program interface (API) of said middleware.

11. The system of claim 10, wherein said mobile application comprises:

an object relational mapping layer configured to interact with one or more object oriented programming language objects;

a messaging object mapping layer; and

a device persistence library associated with said messaging object mapping layer configured to store data associated with said mobile application.

12. The system of claim 11, wherein said mobile application further comprises a state management module configured to determine status of said stored data.

13. The system of claim 11, wherein said mobile application further comprises a data security module configured to determine security characteristics of said stored data.

14. The system of claim 11, wherein said mobile application further comprises a local database configured to store data retrieved from said remote data source.

15. The system of claim 11, wherein said mobile application further comprises a local messaging cache configured to store messaging data associated with said mobile application.

16. A computer program product having control logic stored therein, said control logic enabling one or more processors to abstract data in a remote data source for use by a mobile device having occasional connectivity according to a method, the method comprising:

defining said data source;

defining a data synchronization methodology for communication with said data source; and

providing an abstraction layer for accessing data in said data source, said abstraction layer implementing said data synchronization methodology when data is accessed through said abstraction layer.

17. The computer program product of claim 16, the method further comprising:

defining a method by which said data is provided by said remote data source to said mobile device.

18. The computer program product of claim 16, the method further comprising:

interfacing with a mobile business object (MBO).

19. The computer program product of claim 18, the method further comprising:

defining security characteristics of said MBO;

defining data synchronization characteristics of said MBO; and

defining relationships between said MBO and other MBOs.

20. The computer program product of claim 18, the method further comprising:

defining in-bound invocation methods for said MBO.
