The Macrotec toolset for CASE-based business modelling

A new methodology for the architectural modeling and high-level requirements specification of business processes and information systems has been developed. The Macrotec toolset has been created to support and validate the methodology. Macrotec currently allows for graphical model specification, automatic graphical layout, logical and performance analysis, and hierarchical decomposition. Various tools were built or integrated into Macrotec to support this functionality. Externally, integration is achieved through a seamless user interface, and internally, integration is furthered by one single data representation scheme and a simple yet effective and extensible mechanism for tool interaction. The methodology and the CASE tool development effort that led to Macrotec are described. Macrotec's requirements, design and implementation are discussed, and the development effort is evaluated.
