Abstract

A system for processing rules on data elements is described. The system includes a memory queue configured to receive and store a listing of data elements and a rule processing engine configured to apply one or more processing rules to one or more data elements. The rules processing engine further includes a rule condition processing engine configured to apply a condition to a data element and store the data element in the memory queue if the condition is satisfied and a rule action processing engine configured to iteratively perform an action on the elements stored in the memory queue.

Claims

1. A system for processing rules on data elements, comprising:

a memory queue configured to receive and store a listing of data elements; and

a rule processing engine configured to apply one or more processing rules to one or more data elements, including;

a rule condition processing engine configured to apply a condition to a data element and store the data element in the memory queue if the condition is satisfied and

a rule action processing engine configured to iteratively perform an action on the elements stored in the memory queue.

2. The system of claim 1, wherein the rule action processing engine is configured to perform the action on the elements in the memory queue without additional processing.

3. The system of claim 1, wherein the data elements are representative of articles for sale in a retail sales environment.

4. The system of claim 1, wherein applying a condition to a data element includes determining whether a data element field associated with the data element satisfies the condition.

5. The system of claim 1, wherein storing the data element in the memory queue includes pre-processing the data element to prepare for the action to be taken by the rule action processing engine.

6. The system of claim 5, wherein pre-processing the data element includes pre-fetching and preparation of a data element field from the data element.

7. The system of claim 1, wherein the rule action processing engine is configured to perform rule execution preparation overhead prior to performing the action on the data elements in the memory queue.

8. A method for processing a rule on one or more data elements, comprising:

retrieving one or more data elements;

performing condition rule execution processing overhead;

storing the retrieved data elements that satisfy a condition in a memory queue;

performing rule execution preparation; and

processing the rule for each of the data elements in the memory queue.

9. The method of claim 8, wherein processing the rule for each of the data elements in the memory queue is performed without further performing rule execution preparation.

10. The method of claim 8, wherein the data elements are representative of articles for sale in a retail sales environment.

11. The method of claim 8, data elements satisfy a condition if a data element field associated with the data element satisfies the condition.

12. The method of claim 8, wherein storing the data element in the memory queue includes pre-processing the data element to prepare for the rule processing.

13. The method of claim 12, wherein pre-processing the data element includes pre-fetching and preparation of a data element field from the data element.

14. The method of claim 8, wherein retrieving one or more data elements includes generating a pointer to the location of the data element in memory.

15. A system for processing rules on data elements, comprising:

a memory queue configured to receive and store a listing of data elements, each data element including a plurality of data element fields and representing a good for sale in a retail environment; and

a rule processing engine configured to apply one or more processing rules to one or more data elements, including;

a rule condition processing engine configured to apply a condition to a data element and store the data element in the memory queue if the condition is satisfied and

a rule action processing engine configured to iteratively perform an action on the elements stored in the memory queue.

16. The system of claim 15, wherein the rule action processing engine is configured to perform the action on the elements in the memory queue without additional processing.

17. The system of claim 15, wherein applying a condition to a data element includes determining whether a data element field associated with the data element satisfies the condition.

18. The system of claim 15, wherein storing the data element in the memory queue includes pre-processing the data element to prepare for the action to be taken by the rule action processing engine.

19. The system of claim 18, wherein pre-processing the data element includes pre-fetching and preparation of a data element field from the data element.

20. The system of claim 15, wherein the rule action processing engine is configured to perform rule execution preparation overhead prior to performing the action on the data elements in the memory queue.
