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 computerized method for creating an offline enterprise application from an online enterprise application, the method comprising:

importing data from the online enterprise application to an offline system based on data subscription rules, wherein the data comprises user interface (UI) metadata, enterprise service repository (ESR) data, and application data;

creating the offline enterprise application for the offline system automatically from the imported data by generating an offline UI from the imported UI metadata, and generating enterprise services from the imported ESR data, wherein the offline UI access the enterprise services by connecting to an offline enterprise server via an enterprise service infrastructure (ESI) service layer; and

customizing the generated enterprise services by adding a specific business logic to the generated enterprise services.

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

importing the UI metadata from an online UI metadata repository to an offline UI metadata repository;

importing the ESR data from an online ESR to an offline ESR; and

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

3. The computerized method of 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.

4. The computerized method of claim 1, wherein the data subscription rules determine which application data are transferred from the online enterprise application to the offline system.

5. The computerized method of 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.

6. The computerized method of claim 1, wherein creating the offline enterprise application is triggered by an event.

7. A system for creating an offline enterprise application from an online enterprise application, the system comprising:

a user interface (UI) metadata import tool to import UI metadata from the online enterprise application of an online system to an offline system based on data subscription rules;

an enterprise service repository (ESR) import tool to import ESR data from the online enterprise application of the online system to the offline system based on the data subscription rules; and

a data synchronization system to transfer application data from the online enterprise application of the online system to the offline system based on the data subscription rules, wherein the offline enterprise application is created automatically by;

generating an offline UI from the imported UI metadata;

generating enterprise services from the imported ESR data, wherein the offline UI accesses the enterprise services by connecting to an offline enterprise server via a enterprise service infrastructure (ESI) service layer; and

customizing the generated enterprise services by adding a specific business logic to the generated enterprise services.

8. The system of claim 7, wherein the offline system further comprises:

a processor in communication with a memory;

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

the offline enterprise server that provides the enterprise services;

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

the ESI service layer that connects the offline enterprise server to the UI; and

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

9. The system of claim 7, wherein the online system further comprises:

a processor in communication with a memory;

an online user interface (UI) metadata repository stored 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 the online enterprise application.

10. The system of claim 8, 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.

11. The system of claim 7, wherein the online system, offline system and data synchronization system communicate over a communication network.

13. The article of manufacture of claim 10, wherein the data subscription rules determine which application data are transferred from the online enterprise application to the offline system.

14. The article of manufacture of claim 13, wherein importing the application data from the online database to the offline database comprises creating the offline database based on the imported ESR data.

15. The article of manufacture of claim 14, wherein the data subscription rules determine which application data are transferred from the online enterprise application to the offline system.

12. An article of manufacture, comprising:

a machine readable storage 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 based on data subscription rules, wherein the data comprises user interface (UI) metadata, enterprise service repository (ESR) data and application data;

creating an offline enterprise application for the offline system automatically from the imported data by generating an offline UI from the imported UI metadata, and generating enterprise services from the imported ESR data, wherein the offline UI access the enterprise services by connecting to an offline enterprise server via an enterprise service infrastructure (ESI) service layer; and

customizing the generated enterprise services by adding a specific business logic to the generated enterprise services.

16. The article of manufacture of claim 12, 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.
