7. The system of claim 1 , wherein the set of COBOL data is a COBOL data file.
1. A system comprising: a non-transitory computer-readable medium storing computer-executable code, the computer-executable code comprising: a client interface module for generating an interface for receiving a copybook selection, the client interface module is configured for communication to receive the copybook selection; an import module for importing a copybook from a database, the copybook corresponding with a set of COBOL data stored in the database that includes a REDEFINE clause, the import module is configured for communication to receive the copybook selection from the client interface module and to import the copybook from the database; an object model module for creating an object model for the copybook, the object model module is configured for communication to receive the copybook from the import module and store the object model in a model library; and a modeler module for receiving the set of COBOL data and forming, based at least in part on the received set of COBOL data, an object instance that is equivalent to the set of COBOL data, the object instance including one or more representations for a complete set of one or more properties included in the REDEFINE clause without requiring custom coding for the forming of the object instance, the modeler module is configured for communication to receive the set of COBOL data from the database and to retrieve the object model from the model library, the modeler module including an REDEFINE module for identifying an instance of the REDEFINE clause and automatically forming the REDEFINE clause as the object instance, the REDEFINE module is configured to read the set of COBOL data.
