receiving a name and definition for a re-usable code component as text;

converting the text for the name and the definition to a mark-up language; and

generating the re-usable code component based on the mark-up language for integration into an interface.

3. The method of claim 2 , wherein the text is received as input to input fields of an interface.

4. The method of claim 1 , wherein the automatically generating an updated code definition of the re-usable component based on the customization code includes:

updating an attribute of the code definition of the re-usable component based on the customization code, wherein the updating includes specifying at least one database.

5. The method of claim 4 , further including:

accessing at least one value from the database;

automatically executing the code definition based on the value; and

presenting results across an interface page generated by the execution.

6. The method of claim 1 , wherein the code definition specifies a manner to render output.

7. The method of claim 1 , wherein the receiving from a user customization code includes:

receiving an input via another re-usable component of an interface page, the another re-usable component different from the re-usable component.

8. The method of claim 1 , further including:

receiving a reference within a page to the re-usable component, the reference including code for specifying a manner to render output; and

wherein the automatically generating an updated code definition of the re-usable component based on the customization code includes:

inserting the code for specifying a manner to render output within an area of the re-usable component for receiving input of an unspecified type.

9. The method of claim 8 , wherein the code that specifies a manner to render output includes code for modifying a resulting output of a first re-usable component that takes as input an output of a second re-usable component.

10. The method of claim 1 , wherein the code definition includes one or more restrictions placed on types of changes that a user may make to the re-usable component.

11. The method of claim 1 , further including checking that an identifier includes a name available to the specific client.

12. The method of claim 1 , further including checking that an identifier is not yet used to refer to any other re-usable component of other users.

13. A method of automatically creating a re-usable component for a user-interface, the method including:

receiving by a server of a shared on-demand database a request to include, in a code definition of a first re-usable component having access to one or more fields of the shared on-demand database, a reference to a body re-usable component;

responsive to the request, automatically generating a name and a code definition for a second re-usable component based on at least:

a next unique identifier in a sequence of not yet used unique identifiers that are available and are valid for a specific client; and

a code definition of a pre-determined re-usable component template; and

instantiating a second re-usable component from the first re-usable component the instantiating based on the name, as automatically generated, and code definition of the body re-usable component; and

presenting the second re-usable component as a panel portion for display across an interface in a package received by and installed at a specific client; thereby enabling customizing the interface installed at and specific to the specific client with a re-usable component including customization code used among a plurality of users in interfaces installed at and customized to respective ones of the plurality of users.

14. The method of claim 11 , wherein automatically generating a name and a code definition for the second re-usable component includes:

receiving the name and code definition of the body re-usable component as text;

converting the text for the name and the code definition to a mark-up language; and

generating the code definition for a second re-usable component based on the mark-up language for integration into an interface.

15. The method of claim 14 , wherein the text is received as input to input fields of an interface.

16. A non-transitory computer readable storage medium impressed with computer program instructions to automatically create a re-usable component for a user-interface, which instructions, when executed on a processor, implement a method comprising:

automatically generating by a server of a shared on-demand database a re-usable component having access to one or more fields of the shared on-demand database based on a next unique identifier in a sequence of not yet used unique identifiers that are available and are valid for a specific client;

wherein the re-usable component includes a code definition adopted from a pre-determined re-usable component template;

presenting the re-usable component as an interface portion for display across an interface installed at and specific to a client;

receiving from a user, customization code that modifies a functionality of the re-usable component;

automatically generating an updated code definition of the re-usable component modified based on the customization code;

creating a new re-usable component in accordance with the updated code definition; and

presenting the new re-usable component in place of the re-usable component as the interface portion for display across the interface in a package received by and installed at a specific client; thereby enabling customizing the interface installed at and specific to the client with a re-usable component including the customization code used among a plurality of users in interfaces installed at and customized to respective ones of the plurality of users.

17. The non-transitory computer readable storage medium of claim 16 , implementing the method further comprising:

updating an attribute of the code definition of the re-usable component based on the customization code, wherein the updating includes specifying at least one database;

accessing at least one value from the database;

automatically executing the code definition based on the value; and

presenting results generated by the executing the code definition across an interface page.

18. The non-transitory computer readable storage medium of claim 16 , implementing the method further comprising:

receiving a reference within a page to the re-usable component, the reference including code for specifying a manner to render output; and

wherein the automatically generating an updated code definition of the re-usable component based on the customization code includes:

inserting the code for specifying a manner to render output within an area of the re-usable component for receiving input of an unspecified type.

19. The non-transitory computer readable storage medium of claim 18 , wherein the code that specifies a manner to render output includes code for modifying a resulting output of a first re-usable component that takes as input an output of a second re-usable component.

20. The non-transitory computer readable storage medium of claim 16 , wherein the code definition includes one or more restrictions placed on types of changes that a user may make to the re-usable component.

21. The non-transitory computer readable storage medium of claim 16 , implementing the method further comprising: checking that an identifier includes a name available to the specific client.

22. The non-transitory computer readable storage medium of claim 16 , implementing the method further comprising: checking that an identifier is not yet used to refer to any other re-usable component of other users.
