Abstract

Disclosed is a method and apparatus for automatically creating an offline enterprise application from an online enterprise application by importing the data from the online enterprise application to an offline system, including importing user interface (UI) metadata, enterprise services repository (ESR) data and application data from the online enterprise application and generating the UI and enterprise services from the imported UI metadata and ESR data respectively. The created offline enterprise application switches automatically between offline mode and online mode.

Claims

1. A method, comprising:

importing data from an online enterprise application to an offline system; and

creating an offline enterprise application for the offline system automatically from the imported data.

2. The method in claim 1, wherein importing data comprises:

importing user interface (UI) metadata from an online UI metadata repository to an offline UI metadata repository;

importing enterprise service repository (ESR) data from an online ESR to an offline ESR; and

importing application data from an online database to an offline database.

3. The method in claim 1, wherein creating the offline enterprise application from the imported data comprises:

generating a UI from the imported UI metadata; and

generating enterprise services from the imported ESR data.

4. The method in claim 3, wherein the generated enterprise services comprises adding specific business logic to the generated enterprise services.

5. The method in claim 2, wherein importing the application data from the online database to the offline database comprises creating the offline database based on the imported ESR data.

6. The method in claim 5, further comprising transferring data between the online and the offline database based on data subscription rules that determine which application data are transferred.

7. The method in claim 1, wherein the offline enterprise application further comprises automatically switching between an offline mode and an online mode based on the availability of the connection to an online enterprise server.

8. The method in claim 1, wherein creating the offline enterprise application is triggered by an event.

9. A system, comprising:

an offline system running an enterprise application in an offline mode;

an online system running an enterprise application in an online mode;

a first data importing tool that imports user interface (UI) metadata from the online system to the offline system;

a second data importing tool that imports enterprise service repository (ESR) data from the online system to the offline system; and

a data synchronization system that transfers application data between the offline system and the online system.

10. The system of claim 9 wherein the offline system further comprises:

a processor in communication with a memory;

an offline user interface (UI) metadata repository in the memory;

an offline enterprise server that provides enterprise services;

an offline enterprise service repository (ESR) in the offline enterprise server that contains metadata of the enterprise services;

an enterprise service infrastructure (ESI) service layer that connects the offline enterprise server to the UI; and

an offline database that comprises application data of an offline enterprise application.

11. The system of claim 9, wherein the online system further comprises:

a processor in communication with a memory;

an online user interface (UI) metadata repository in the memory;

an online enterprise server that provides enterprise services;

an online enterprise service repository (ESR) in the enterprise server that contains metadata of the enterprise services;

an enterprise service infrastructure (ESI) service layer that connects the UI to the online enterprise server over a communication network; and

an online database that comprises application data of an online enterprise application.

12. The system of claim 10, wherein the ESI service layer of the offline system further comprises an automatic switch between the enterprise server of the online system and the offline system based on the connection mode.

13. The system of claim 9 wherein the online system, offline system and data synchronization system communicate over a communication network.

14. An article of manufacture, comprising:

a machine readable medium having instructions that when executed by a machine cause the machine to execute a method, comprising;

importing data from an online enterprise application to an offline system; and

creating an offline enterprise application for the offline system automatically from the imported data.

15. The article of manufacture in claim 14, wherein importing data comprises:

importing user interface (UI) metadata from an online UI metadata repository to an offline UI metadata repository;

importing enterprise service repository (ESR) data from an online ESR to an offline ESR; and

importing application data from an online database to an offline database.

16. The article of manufacture in claim 14, wherein creating the offline enterprise application from the imported data comprises:

generating a UI from the imported UI metadata; and

generating enterprise services from the imported ESR data.

17. The article of manufacture in claim 16, wherein the generated enterprise services comprises instructions for adding specific business logic to the generated enterprise services.

18. The article of manufacture in claim 15, wherein importing the application data from the online database to the offline database comprises creating the offline database based on the imported ESR data.

19. The article of manufacture in claim 18 further comprising instructions for transferring data between online and offline database based on data subscription rules that determine which application data are transferred.

20. The article of manufacture in claim 14, wherein the offline enterprise application further comprises instructions for automatically switching between an offline mode and an online mode based on the availability of the connection to an online enterprise server.
