Abstract

A rule construction and application technique is disclosed wherein atomic rules are used alone or in combination with template rules in order to construct complex rules. The complex rules may be stored and/or applied to objects, and may also be used to generate further rules. A domain agent is disclosed that acts to operate between the object and the rule.

Claims

1. A method of constructing rules for use in examining queries in a database query management system comprising:

storing a set of atomic rules in a database;

determining a complex rule to be constructed by utilizing an automated process;

constructing the determined complex rule from said atomic rules in said database wherein said atomic rules and said complex rules being operable on queries in said database query management system and said constructed complex rule is different from said atomic rules from which it is constructed;

defining a domain agent; and

utilizing said domain agent to interface between said complex rule and an object upon which said complex rule operates.

2. The method of claim 1 wherein said complex rule is utilized with other atomic rules to construct a second complex rule.

3. The method of claim 2 wherein said complex rule is utilized immediately after being constructed to operate on an object.

4. The method of claim 2 wherein said complex rule is stored after being constructed for later use.

5. The method of claim 1 wherein said step of constructing further includes the step of combining atomic rules with template rules.

6. The method of claim 5 wherein said template rules are updated periodically.

7. The method of claim 1 where the automated process is an induction process.

8. The method of claim 1 wherein said complex rule is a rule about constructing new rules.

9. The method of claim 1 wherein said complex rule is utilized with other atomic rules to construct a second complex rule.
