Abstract: This study aims at proposing transformation technique to build OWL ontology from relational database resources by following SQL-DDL (Structured Query Language-Data Definition Language) written version. Though, the databases has proposed the best form of techniques in order to store in memory for the purpose of managing data and retrieving data or for the purpose of recovering it for further functions. However, databases has been observed semantically absence in achieving world-wide objectives based on both web and data integration semantically. Semantic web is supported by ontology that has ability to represent data in meaningful, rich and readable form for both human and machine. This issue can be overcome through ontology would help in improving databases by semantic functions. This approach can capture meta-data from tuples by analysis of database relations. The meta-data can assist to take out several features of semantic and would not infer from Structured Query Language (SQL). As conceptual model is richer in semantics, so this study gets conceptual (EER) model by applying reverse engineering technique. Finally, the generated ontology is validated and enhanced through comparison with that of database conceptual model which is also known as EER diagram, for achieving the highest ontology.
