ABSTRACT The object relational database (ORDB) management systems signify a set of interrelated objects using reference and collection attributes. The static classlevel design metrics for designing ORDB dictates the structural complexity of the object-relational schema, whereas the dynamic nature of the ORDB demands object-level assessment using runtime metrics which help determine the functional complexity of the database. Runtime coupling and cohesion metrics are deemed appropriate in measuring the Object-level behavioral complexity.In this work we use the runtime cohesion and coupling metrics for studying the dynamic behavior of ORDB by measuring the behavioral complexity of the objects in ORDBs. Experiments on sample ORDB schemas are conducted using statistical analysis and correlation clustering techniques to assess the dynamic behavior of the objects in real time relational environment. The results indicate that the object behavior in ORDB directly influences the database performance. The future works pertaining to this research form the concluding note.
