General object-oriented software development: background and experience

A project involving the development of a simulation system in Ada in parallel with a similar Fortran development has been undertaken. As part of the project, the Ada development team evaluated object-oriented and process-oriented design methodologies for Ada. Finding these methodologies limited in various ways, the team created a general object-oriented development methodology that they applied to the project. The author provides some background on the development of the methodology, describes the main principles of the approach, and presents some experiences using the methodology, including a general comparison of the Ada an Fortran simulator designs.<>
