Abstract

A cache management system comprises a cache adapted store data corresponding to a data source. The cache management system also comprises a cache manager adapted to access a set of rules to determine a frequency for automatically updating the data in the cache. The cache manager is also adapted to automatically communicate with the data source to update the data in the cache corresponding to the determined frequency.

Claims

1. A cache management system, comprising:

a cache adapted to store data corresponding to a data source; and

a cache manager adapted to access a set of rules to determine a frequency for automatically updating the data in the cache, the cache manager adapted to automatically communicate with the data source to update the data in the cache corresponding to the determined frequency.

2. The system of claim 1, wherein the set of rules comprises data attribute rules having information associated with attributes of the data.

3. The system of claim 1, wherein the cache manager is adapted to automatically update the data in the cache corresponding to attributes of the data.

4. The system of claim 1, wherein the set of rules comprises request frequency rules having information associated with a request frequency for the data.

5. The system of claim 1, wherein the cache manager is adapted to automatically update the data in the cache corresponding to a frequency of user requests for the data.

6. The system of claim 1, wherein the set of rules comprises update frequency rules having information associated with an update frequency at the data source.

7. The system of claim 1, wherein the cache manager is adapted to automatically update the data in the cache corresponding to a frequency of updates at the data source.

8. The system of claim 1, further comprising a scheduler adapted to automatically schedule a communication link with the data source corresponding to the frequency.

9. The system of claim 1, wherein the cache manager is adapted to automatically purge the data from the cache if a frequency of updates at the data source exceeds a predetermined frequency limit.

10. The system of claim 1, wherein the cache manager is adapted to automatically update the data in the cache based on an update frequency at the data source and a frequency of user requests for the data.

11. A method for cache management, comprising:

storing data associated with a data source in a cache;

accessing a set of rules to determine a frequency for automatically updating the data in the cache;

automatically initiating communications with the data source corresponding to the determined frequency; and

automatically updating the data in the cache corresponding to the determined frequency.

12. The method of claim 11, wherein accessing a set of rules comprises accessing data attribute rules having information associated with attributes of the data.

13. The method of claim 11, further comprising determining the frequency for updating the data in the cache corresponding to the attributes of the data.

14. The method of claim 11, wherein accessing a set of rules comprises accessing request frequency rules having information associated with a frequency of requests for the data.

15. The method of claim 11, further comprising determining the frequency for updating the data in the cache corresponding to the frequency of user requests for the data.

16. The method of claim 11, wherein accessing a set of rules comprises accessing update frequency rules having information associated with a frequency of updates at the data source.

17. The method of claim 11, further comprising determining the frequency for updating the data in the cache corresponding to a frequency of updates at the data source.

18. The method of claim 11, further comprising automatically purging the data from the cache if an update frequency at the data source exceeds a predetermined frequency limit.

19. The method of claim 11, further comprising automatically scheduling a communication link with the data source corresponding to the determined frequency.

20. A cache management system, comprising:

means for storing data in a cache;

means for automatically determining a frequency for updating the data in the cache;

means for automatically initiating communications with the data source corresponding to the determined frequency; and

means for automatically updating the data in the cache corresponding to the determined frequency.

21. The system of claim 20, wherein the means for determining a frequency comprises means for determining a frequency for updating the data in the cache corresponding to attributes of the data.

22. The system of claim 20, wherein the means for determining a frequency comprises means for determining a frequency for updating the data in the cache corresponding to a frequency of updates at a data source.

23. The system of claim 20, wherein the means for determining a frequency comprises means for determining a frequency for updating the data in the cache corresponding to a frequency of user requests for the data.

24. The system of claim 20, further comprising means for automatically scheduling a communication link with a data source corresponding to the determined frequency.

25. The system of claim 20, further comprising means for automatically purging the data from the cache if a frequency of updates at a data source exceeds a predetermined frequency limit.

26. The system of claim 20, wherein the means for determining a frequency comprises means for determining a frequency for updating the data in the cache based on an update frequency at a data source and a frequency of user requests for the data.

27. A cache management system, comprising:

a cache adapted to store data corresponding to a data source;

a cache manager adapted to automatically determine a frequency for updating the data stored in the cache; and

a scheduler adapted to automatically schedule a communication link with the data source corresponding to the determined frequency.

28. The system of claim 27, wherein the cache manager is adapted to determine the frequency using information associated with attributes of the data.

29. The system of claim 27, wherein the cache manager is adapted to determine the frequency using information associated with a frequency of user requests for the data.

30. The system of claim 27, wherein the cache manager is adapted to determine the frequency using information associated with a frequency of updates at the data source.

31. The system of claim 27, wherein the cache manager is adapted to automatically purge the data from the cache if a frequency of updates at the data source exceeds a predetermined frequency limit.

32. The system of claim 27, wherein the cache manager is adapted to determine the frequency based on an update frequency at the data source and a frequency of user requests for the data.

33. The system of claim 27, further comprising a set of attribute rules accessible by the cache manager, the attribute rules comprising information associated with attributes of the data for determining the update frequency.

34. The system of claim 27, further comprising a set of request frequency rules accessible by the cache manager, the request frequency rules comprising information associated with a user request frequency for the data for determining the update frequency.

35. The system of claim 27, further comprising a set of update frequency rules accessible by the cache manager, the update frequency rules comprising information associated with a frequency of updates at the data source for determining the update frequency.
