Reconstruction of the Conceptual Model from the Implemented Database

The paper deals with reconstructing the conceptual model from the implemented database. Sometimes the conceptual model of the implemented database is missing and is appropriate to reconstruct the conceptual model from the implemented database to understand the content of the database and for effective additional development or maintained. The authors propose algorithm for reconstruction the conceptual model from the implemented database using JDBC methods. Reconstructed conceptual model is represented by XML document and then is transformed to CDM file supported by CASE tool called Sybase PowerDesigner. Finally, reconstructed conceptual model imported to Sybase PowerDesigner can be used for vizualization, transformation to logical and physical model, and in other various ways.
