Abstract

Embodiments consistent with the invention transform business application logic entities or structures into OOP structures that represent the data, relationships, and operations of the business application structures. The business application structures are transformed from the application level, including consideration of the business application logic and relationships. In one embodiment, transformation is done using a set of automated transformation rules. The resulting OOP structure model of the business application structure may be used with OOP tools to analyze, maintain, debug, modify, and revise the business application structure, and to create new structures for the business application.

Claims

1. A method for modeling data structures from a business application in an object-oriented programming language, comprising:

identifying a plurality of table-based data structures for the business application;

identifying a plurality of attributes common to the plurality of table-based data structures;

defining an object-oriented programming language superclass to model the plurality of table-based data structures, wherein the superclass includes a plurality of variables corresponding to the plurality of attributes common to the plurality of table-based data structures;

defining an object-oriented programming language subclass to model a table-based data structure from the plurality of table-based data structures in the business application, wherein the subclass includes a variable corresponding to an attribute not common to the plurality of table-based data structures;

instantiating an object from the subclass, wherein the object represents the table-based data structure;

manipulating the object using an object-oriented programming tool;

converting, using a processor, the manipulated object into a manipulated table-based data structure usable by the business application; and

loading the manipulated table-based data structure into the business application to affect an operation of the business application.

2. The method of claim 1, further comprising:

displaying the object using the object-oriented programming tool.

3. The method of claim 1, further comprising:

detecting a problem associated with the object using the object-oriented programming tool, wherein the problem corresponds to a problem in the table-based data structure.
