MetaCASE tool modeling concepts. Typically they also find it difficult to map the concepts and semantics used in the models to their application domain. After creating the models, which fail even to illustrate the application domain adequately, the tool does not provide the necessary reports nor does it generate the required code. What is needed then is the ability to easily capture the specifications of any method and then to generate CASE tools automatically from these specifications. Later when the situation in the application domain evolves and the development environment changes you may incrementally update the method support in your CASE tool.
