Abstract

In various embodiments, a programmable apparatus for use in a computing environment is provided. The apparatus may include a business rules engine having at least one rule executable by a mainframe system and stored based on an extensible language; and, a business rules engine builder interface configured to access the business rules engine and which permits user selection from among different rules collections in the business rules engine.

Claims

1. A programmable apparatus for use in a computing environment, the apparatus comprising:

a business rules engine coupled to a processor in a mainframe system and at least one data storage medium, the business rules engine including at least one rule executable by the mainframe system in a mainframe computing environment, the business rules engine having the at least one rule stored therein based on an extensible language;

a business rules engine builder interface coupled to a processor in a distributed computing environment, the business rules engine builder interface accessing the business rules engine, and the business rules engine builder interface permitting selection from among different rules collections in the business rules engine and modification of the at least one rule based on a selection of at least one configurable parameter of the at least one rule; and

wherein the business rules engine supports execution in the mainframe computing environment of at least one rule defined with the business rules engine builder interface in the distributed computing environment.

2. The apparatus of claim 1, wherein at least one of the rules collections includes a true/false rules collection.

3. The apparatus of claim 1, wherein the business rules engine builder interface permits modification of a rule description based on a user input.

4. The apparatus of claim 1, wherein the business rules engine builder interface permits modification of a rule type based on a user input.

5. The apparatus of claim 1, wherein the business rules engine builder interface permits modification of a rule trigger based on a user input.

6. The apparatus of claim 1, wherein the business rules engine builder interface permits modification of a rule trigger level based on a user input.

8. The apparatus of claim 1, wherein a result from the business rules engine builder interface is provided in an XML format.

9. The apparatus of claim 1, wherein the business rules engine communicates with an Enterprise Application Integration (“

EAI”

) framework of the mainframe system and is triggered based on data processed by the mainframe system.

10. The apparatus of claim 1, wherein the business rules engine comprises at least one configurable screen definition.

11. The apparatus of claim 10, wherein the at least one configurable screen definition determines whether at least one element is accessed on an interface, wherein the at least one element is selected from the group consisting of a label, a table, a pick list, a drop-down menu, a check box, and a radio button.

12. The apparatus of claim 10, wherein the at least one configurable screen definition determines whether at least one complex object is applied to a screen.

13. The apparatus of claim 1, wherein at least one of a before rule and an after rule stored in the business rules engine is accessed in response to an evaluation from the mainframe system.

14. The apparatus of claim 11, wherein the before rule and the after rule comprise application logic employed by the mainframe system that is stored as XML-based data.

15. The apparatus of claim 1, wherein a portion of the distributed computing environment performs an XSLT transformation and causes source code to be generated that can be processed by a browser of a user as part of returning communications data to the user.

16. The apparatus of claim 4, wherein the rule type comprises at least one rule data type and wherein the at least one rule data type is used to set a field in state data based on a lookup into an edit table.

7. A programmable apparatus for use in a computing environment, the apparatus comprising:

a business rules engine coupled to a processor in a mainframe system and at least one data storage medium, the business rules engine including at least one rule executable by the mainframe system in a mainframe computing environment, the business rules engine having at least one rule stored therein based on an extensible language;

a business rules engine builder interface coupled to a processor in a distributed computing environment, the business rules engine builder interface accessing the business rules engine, and the business rules engine builder interface permitting selection from among different rules collections in the business rules engine; and

wherein at least one of the rules collections includes a true/false rules collection, and wherein the business rules engine builder interface permits modification of the at least one rule based on a selection of at least one configurable parameter of the at least one rule, the at least configurable parameter comprising at least one of a rule description, a rule type, a rule trigger operator, and a rule trigger level; and

wherein the business rules engine supports execution in the mainframe computing environment of at least one rule defined with the business rules engine builder interface in the distributed computing environment.

17. A computer readable non-transitory computer readable medium having instruction for executing a method for providing business rules data between a user device and a mainframe system, the method comprising:

retrieving state data from the mainframe system;

receiving input data from a user device and parsing the input data;

updating the state data based on the input data and in response to receiving the input data;

invoking a business rules engine coupled to a processor in the mainframe system;

the business rules engine evaluating at least one predetermined rule associated with a current interface or application of the user device;

applying the at least one predetermined rule associated with the current interface or application of the user device;

the mainframe system retrieving a presentation layer outline;

the mainframe system evaluating the presentation layer outline on a display object basis;

the mainframe system creating an output message based on the evaluated presentation layer outline;

communicating the output message to the user device.

18. The method of claim 17 further comprising storing the updated state data to a persistency layer of the mainframe system and performing an XSLT transformation on the output message such that the output message can be viewed on a browser of the user device.

19. The method of claim 17 wherein the mainframe system evaluating the presentation layer outline on the display object basis comprises interrogating each display object of the presentation layer outline based on at least one of determination criteria.

20. The method of claim 19 wherein the at least one determination criteria comprises at least one of determining whether each display object is based on a business rules, determining an object type of each display object, determining an object attribute of each display object, determining an object properties of each display object, determining how each display object is populated, and determining object events for each display object.
