Abstract
In spite of advances in database technology, huge amounts of data around the world are still managed in files and accessed by COBOL application programs. It is a major challenge to migrate this data and these applications to modern database technology.This work provides a basis for overcoming the mismatch between the data model of COBOL and modern object-oriented or semantic data models. We propose an algorithm to determine references and inclusion dependencies in a COBOL data structure. This information makes it possible to generate a schema in any data model, be it a semantic data model like the entity-relationship model, an object-oriented model like ODMG-93 or the relational model.KeywordsData ItemFunctional DependencyReverse EngineeringObject TypeStructure ResolutionThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
