Abstract

A system and method for automatically generating and controlling workflows that include a number of processes uses a workflow server computer and a client computer coupled to the workflow server by a network. The workflow server computer has an object repository and a rule engine. The client computer has a workflow builder structure and a graphical user interface. The workflow builder structure includes a rule builder by which users can interactively construct rules for a workflow.

Claims

1. A system for automatically generating and controlling workflows including a plurality of workflow processes, the system comprising:

a server computer including an object repository and a first rule engine;

a client computer operatively coupled to the server computer, the client computer including a workflow builder structure, a graphical user interface, and a script handler in which a second rule engine is disposed, wherein the workflow builder structure generates workflows that include steps for routing objects retrieved from the object repository in response to user control of the graphical user interface, wherein said second rule engine evaluates said objects, and wherein the script handler processes said steps of said workflows and routes said objects.

2. A system as in claim 1, wherein ones of said steps correspond to ones of said workflow processes responsive to step performance by said server computer, and to external application processes responsive to step performance by said script handler.

3. A system as in claim 1, wherein said first rule engine and said second rule engine are identical.

4. A computer-implemented method of automatically generating and controlling workflows, the workflows including a plurality of processes, the method comprising:

generating, by a workflow builder structure of a client computer, a workflow that includes steps for routing objects retrieved from an object repository;

connecting said client computer to a server computer in which is disposed said object repository and a first rule engine;

routing said objects by said first rule engine to said client computer;

evaluating said objects by a second rule engine disposed in said client computer; and

routing said objects by a script handler disposed in said client computer in response to the results of said evaluating.

5. A method as in claim 4, further comprising processing said steps by said script handler controlling at least one external application process.

6. A method as in claim 4, further comprising implementing said first rule engine and said second rule engine identically.
