Improving Business Logic Expression with OCL and CASE Tool

Traditionally software testing is performed at the coding stage and is costly. Prior research indicated that if the errors can be found prior to the coding stage, the cost for fixing the errors can be reduced. Today, Unified Modeling Language (UML) has become a standard modeling language in object-oriented systems analysis and design. Over the past few years a considerable effort has been made in synthesizing UML, MDA (Model-Driven Architecture), and CASE tool to increase the productivity of the system development. Specifying the business logic constraints with Object Constraint Language (OCL) has become a main trend in this area.
This study presents a methodology to specify the business logic constraint with OCL on the platform independent model during the systems analysis and design stage, then transform the OCL expressions into the code model and do the model testing simultaneously with a CASE tool. Three real-world cases and a CASE tool are used to test the usability (including the concepts, application, and advantages) of the proposed methodology. With this approach, software bugs related to business logic constraints can be found at the systems analysis and design stage and thereby reduce the cost of software testing and enhance the efficiency of system development.
