Abstract

A computer-implemented real-time decision support system including means for receiving complex queries posed by a plurality of users; means for providing for each of the queries an executable query process furnishing a result when data sources satisfy constraints of the query; means for providing data sources, the data sources including an event source; means for responding to an event furnished by an event source to initiate execution of all query processes having constraints satisfied by data sources; and means for furnishing results of executed query processes to users.

Claims

1. A computer-implemented real-time decision support system comprising:

means for receiving complex queries posed by a plurality of users;

means for providing for each of the queries an executable query process furnishing a result when data sources satisfy constraints of the query;

means for providing data sources, the data sources including an event source;

means for responding to an event furnished by an event source to initiate execution of all query processes having constraints satisfied by data sources; and

means for furnishing results of executed query processes to users.

2. A system as claimed in claim 1 in which the means for responding to an event comprises means for providing an index for testing whether constraints of a query process match attributes of events.

3. A system as claimed in claim 1 in which all query processes having constraints matching attributes in an event are executed simultaneously.

4. A system as claimed in claim 1 in which a query process is persistent until removed.

5. A system as claimed in claim 1 in which the means for providing for each of the queries an executable query process includes means for changing the query processes for which results are required.

6. A system as claimed in claim 1 in which the means for furnishing results of executed query processes to users comprises means for providing results to users whenever incremental changes in query results occur.

7. A system as claimed in claim 6 in which the means for providing results to users whenever incremental changes in query results occur includes means for determining incremental changes in query results.

8. A system as claimed in claim 1 in which the data sources comprise an event service.

9. A system as claimed in claim 1 in which the means for furnishing results of executed query processes to users comprises an event service.

10. A system as claimed in claim 1 in which the means for providing data sources comprises means for providing historical data.

11. A process for providing the incremental results caused by incrementally-occurring changes in data to complex queries comprising the steps of:

receiving complex queries posed by a plurality of users,

generating an executable query process for providing results required by each of the queries,

receiving data including events from data sources,

responding to events by executing all query processes having constraints satisfied by data sources to provide results required by each of the queries, and

furnishing results of executed query processes to users.

12. A process as claimed in claim 11 in which the step of responding to events comprises testing whether constraints of a query process are satisfied by attributes of events.

13. A process as claimed in claim 11 in which all query processes having constraints satisfied by data sources are executed simultaneously.

14. A process as claimed in claim 11 in which a query process is persistent until removed.

15. A process as claimed in claim 11 in which the step of generating an executable query process includes a step of changing the query process for which results are required while the process is functioning.

16. A process as claimed in claim 11 in which the step of furnishing results of executed query processes to users comprises a step of providing results to users whenever incremental changes in query results occur.

17. A process as claimed in claim 16 in which the step of providing results to users whenever incremental changes in query results occur includes a step of determining incremental changes in query results.

18. A process as claimed in claim 11 in which the step of receiving data including events from data sources utilizes an event service to furnish events.

19. A process as claimed in claim 11 in which the step of furnishing results of executed query processes to users utilizes an event service.

20. A computer-implemented process as claimed in claim 11 in which the step of receiving data including events from data sources includes receiving historical data from a source of historical data.
