Abstract

A server system may include a data dictionary to store platform-independent data types. A development client may access and modify a platform-independent data type stored in the data dictionary. The server system may notify other development clients using the data type that the data type has been modified.

Claims

1. A computer-implemented method comprising:

receiving a request for a data type from a client system; and

providing the data type to the client system in response to the request, wherein the data type includes a platform-independent data type that is independent of platforms associated with the client system.

2. The method of claim 1, wherein providing the platform-independent data type comprises:

providing a markup language based data type from a data dictionary at a server system, the server system including an application server.

3. The method of claim 2, wherein providing the markup language based data type comprises:

providing an Extensible Markup Language (XML) base data type from the data dictionary.

4. The method of claim 3, wherein providing the XML based data type comprises:

providing an XML based simple data type.

5. The method of claim 3, wherein providing the XML based data type comprises:

providing an XML based database data type.

6. The method of claim 3, wherein providing the XML based data type comprises:

providing an XML based complex data type.

7. The method of claim 6, wherein providing the XML based complex data type comprises:

providing an XML based flat structure data type.

8. The method of claim 1, wherein providing the platform-independent data type comprises:

providing the platform-independent data type during design time.

9. The method of claim 1, wherein providing the platform-independent data type comprises:

providing the platform-independent data type that is based, at least in part, on a previously defined data type.

10. A system comprising:

a client system to send a request for a data type to a server system; and

the server system coupled with the client system, the server system to provide the data type to the client system in response to the request, wherein the data type includes a platform-independent data type that is independent of platforms associated with the client system.

11. The system of claim 10, wherein the client system comprises a development environment to develop software applications, the development environment including:

a client system having a Java development environment.

12. The system of claim 11, wherein the platform-independent data type comprises:

an Extensible Markup Language (XML) base data type.

13. The system of claim 12, wherein the server system comprises an application server, the application server including a Web application server.

14. The system of claim 13, wherein the Web application server comprises a Java 2 Enterprise Edition (J2EE) application server.

15. An article of manufacture comprising a machine-readable medium having instructions which when executed, cause a machine to:

receive a request for a data type from a client system; and

provide the data type to the client system in response to the request, wherein the data type includes a platform-independent data type that is independent of platforms associated with the client system.

16. The article of manufacture of claim 15, wherein the instructions when executed to provide the data type having the platform-independent data type, further cause the machine to provide an Extensible Markup Language (XML) based data type.

17. The article of manufacture of claim 16, wherein the instructions when executed to provide the XML based data type, further cause the machine to provide a XML based simple data type.

18. The article of manufacture of claim 16, wherein the instructions when executed to provide the XML based data type, further cause the machine to provide an XML based complex data type.

19. The article of manufacture of claim 16, wherein the instructions when executed to provide the XML based data type further cause the machine to provide an XML based database data type.

20. The article of manufacture of claim 16, wherein the instructions when executed to provide the XML based data type further cause the machine to provide an XML based user interface data type.
