Abstract

Methods and apparatus, including computer program products, that include generating a first application by providing a definition of an object representing a first set of attributes of a first collection of data elements and a first set of operations on the first collection, each data element in the first collection having the attributes and a list of the operations in common with other data elements from the first collection. The method also includes extending the definition of the object with a second definition, the second definition comprising a second set of attributes of the data elements or a list of second set of operations on the data elements, receiving from the client a request to execute an operation from the first set of operations or the second set of operations on one or more data elements from the first collection, the request having input parameters, checking the request against the definition and the second definition, executing, with a first set of parameters, the operation on the one or more data elements of the first collection, the operation resulting in output parameters, and sending a second set of parameters.

Claims

1. A method comprising:

generating a first application by providing a definition of an object representing a first set of attributes of a first collection of data elements and a first set of operations on the first collection, each data element in the first collection having the attributes and a list of the operations in common with other data elements from the first collection;

extending the definition of the object with a second definition, the second definition comprising a second set of attributes of the data elements or a list of second set of operations on the data elements;

receiving from the client a request to execute an operation from the first set of operations or the second set of operations on one or more data elements from the first collection, the request having input parameters;

checking the request against the definition and the second definition;

executing, with a first set of parameters, the operation on the one or more data elements of the first collection, the operation resulting in output parameters; and

sending a second set of parameters.

2. The method of claim 1 wherein the first set of parameters comprise the input parameters and the second parameters comprise the output parameters.

3. The method of claim 1 further comprising providing a definition of a module representing a set of one or more collections of data elements, the set comprising the first collection of data elements, wherein the definition of the module comprises a query on one or more collections of data elements.

4. The method of claim 3 further comprising extending the definition of the module with a second definition, the second definition comprising a second query on one or more collections of the data elements.

5. The method of claim 4 further comprising:

receiving from the client a request to execute the first or second query on one or more collections of the data elements, the request having input parameters;

checking the request against the definition and the second definition of the module;

executing, with a first set of parameters, the query on the one or more collections of the data elements, the operation resulting in output parameters; and

sending a second set of parameters.

6. The method of claim 4 wherein the second definition further comprises a second collection of data elements.

7. The method of claim 6 wherein the second definition further comprises a relation between the first collection and the second collection, the relation enabling a navigation from the first collection to the second collection.

8. The method of claim 5 further comprising:

sending the request with the input parameters;

generating the first set of parameters by modifying the input parameters; and

receiving the first set of parameters.

9. The method of claim 1 or 5 further comprising:

sending the request with the output parameters;

generating the second set of parameters by modifying the output parameters; and

receiving the second set of parameters.

10. The method of claim 1 further comprising:

extending the definition and the second definition of the object with a third definition, the third definition comprising a third set of attributes of the data elements or a third set of operations on the data elements; and

checking the request against the definition, the second definition, and the third definition.

11. The method of claim 4 further comprising extending the definition of the module with a third definition, the third definition comprising a third query on one or more collections of the data elements.

12. The method of claim 1 further comprising:

generating a second application by extending the definition of the object with a third definition, the third definition comprising a third set of attributes of the data elements or a third set of operations on the data elements;

receiving from the client a request to execute an operation from the first set of operations or the third set of operations on one or more data elements from the first collection, the request having input parameters; and

checking the request against the definition and the third definition.

13. A system comprising:

a first computer configured to execute a client program;

a second computer configured to execute a server program;

a network linking the first and second computers such that the server program is configured to execute the following;

provide to the client program a first application with a definition of an object representing a first set of attributes of a first collection of data elements and a list of first set of operations on the first collection, each data element in the first collection having the attributes and the operations in common with other data elements from the first collection;

extend the definition of the object with a second definition, the second definition comprising a second set of attributes of the data elements or a second set of operations on the data elements;

receive from the client program a request to execute an operation from the first set of operations or the second set of operations on one or more data elements from the first collection, the request having input parameters;

check the request against the definition and the second definition;

execute, with a first set of parameters, the operation on the one or more data elements of the first collection, the operation resulting in output parameters; and

send to the client program a second set of parameters.

14. The system of claim 13 wherein the first set of parameters comprise the input parameters and the second parameters comprise the output parameters.

15. The system of claim 13 wherein the server program is further configured to provide a definition of a module representing a set of one or more collections of data elements, the set comprising the first collection of data elements, the definition of the module comprising a query on one or more collections of data elements.

16. The system of claim 15 wherein the server program is further configured to extend the definition of the module with a second definition, the second definition comprising a second query on one or more collections of the data elements.

17. The system of claim 16 wherein the server program is further configured to execute the following:

receive from the client a request to execute the first or second query on one or more collections of the data elements, the request having input parameters;

check the request against the definition and the second definition of the module;

execute, with a first set of parameters, the query on the one or more collections of the data elements, the operation resulting in output parameters; and

send a second set of parameters.

18. The system of claim 16 wherein the second definition further comprises a second collection of data elements.

19. The system of claim 18 wherein the second definition further comprises a relation between the first collection and the second collection, the relation enabling a navigation from the first collection to the second collection.

20. The system of claim 17 wherein the client program is configured to execute the following:

send the request with the input parameters;

generate the first set of parameters by modifying the input parameters; and
