Abstract

Techniques are provided to integrate applications having different data structures. Data from the application having a less restrictive data structure is provided to the application with a more restrictive data structure as the application is capable of storing the data. Data from the application having a less restrictive data structure may be stored.

Claims

1. A computer-implemented method for exchanging computer data in a data exchange between a first data processing system having a less restrictive data structure and a second data processing system having a more restrictive data structure, the method comprising:

receiving from the first data processing system an indication of data to be deleted;

determining whether a data structure associated with the second data processing system permits deleting the indicated data; and

only sending the indication of data to be deleted received from the first data processing system to the second data processing system when the data structure associated with the second data processing system permits deleting the indicated data.

2. The method of claim 1 further comprising when the data structure associated with the second data processing system does not permit deleting the indicated data, sending to the first processing system data to be inserted to replace the indicated data.

3. The method of claim 2 further comprising accessing stored data, wherein sending to the first processing system data to be inserted comprises sending to the first processing system the accessed data to be inserted to replace the indicated data.

4. The method of claim 2 further comprising:

requesting data from the second data processing system; and

receiving data from the second data processing system in response to the request, wherein sending to the first processing system data to be inserted comprises sending to the first processing system the data received from the second data processing system.

5. The method of claim 1 wherein:

the first data processing system comprises a groupware data system, and

the method further comprises receiving an indication of data to be deleted from the groupware data system comprises receiving an indication of groupware data to be deleted from the groupware data system.

6. The method of claim 5 wherein receiving an indication of groupware data from the groupware data system comprises receiving an indication of contact information from the groupware data system.

7. The method of claim 6 wherein receiving an indication of groupware data from the groupware data system comprises receiving an indication of calendar information from the groupware data system.

8. A computer-readable medium or propagated signal having embodied thereon a computer program configured to exchange computer data between a first data processing system having a less restrictive data structure and a second data processing system having a more restrictive data structure, the medium or signal comprising one or more code segments configured to:

receive from the first data processing system an indication of data to be deleted;

determine whether a data structure associated with the second data processing system permits deleting the indicated data; and

only send the indication of data to be deleted received from the first data processing system to the second data processing system when the data structure associated with the second data processing system permits deleting the indicated data.

9. The medium or signal of claim 8 wherein the one or more code segments are further configured to send to the first processing system data to be inserted to replace the indicated data when the data structure associated with the second data processing system does not permit deleting the indicated data.

10. The medium or signal of claim 9 wherein the one or more code segments are further configured to:

access stored data, and

send to the first processing system the accessed data to be inserted to replace the data received.

11. The medium or signal of claim 9 wherein the one or more code segments are further configured to:

request data from the second data processing system,

receive data from the second data processing system in response to the request, and

send to the first processing system the data received from the second data processing system.

12. An apparatus for exchanging computer data between a first data processing system having a less restrictive data structure and a second data processing system having a more restrictive data structure, the apparatus comprising a processor connected to a storage device and one or more input/output devices, wherein the processor is configured to:

receive from the first data processing system an indication of data to be deleted;

determine whether a data structure associated with the second data processing system permits deleting the indicated data; and

only send the indication of data to be deleted received from the first data processing system to the second data processing system when the data structure associated with the second data processing system permits deleting the data received.

13. The apparatus of claim 12 wherein the processor is further configured to send to the first processing system data to be inserted to replace the data received when the data structure associated with the second data processing system does not permit deleting the indicated data.

14. The apparatus of claim 13 wherein the processor is further configured to:

access stored data, and

send to the first processing system the accessed data to be inserted to replace the data received.

15. The apparatus of claim 13 wherein the processor is further configured to:

request data from the second data processing system,

receive data from the second data processing system in response to the request, and

send to the first processing system the data received from the second data processing system.
