1. A system comprising: a non-transitory computer-readable medium storing computer-executable code to integrate legacy COBOL data structures to object instances for object-oriented computer systems, the computer-executable code comprising: a client interface module for generating an interface for receiving a copybook selection, the client interface module adapted 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 dynamic COBOL construct, the import module adapted 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 adapted 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 dynamic COBOL construct without requiring custom coding for the forming of the object instance, the modeler module adapted 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 a dynamic COBOL construct module for identifying an instance of the dynamic COBOL construct and automatically forming the dynamic COBOL construct as the object instance, the dynamic COBOL construct module adapted to read the set of COBOL data.
2. The system of claim 1 wherein the dynamic COBOL construct is a member of a group consisting of an OCCURS DEPENDING ON clause and a REDEFINE clause.
