Object Frameworks - An Empirical Study of Software Architecture Issues

Design of reusable frameworks is an iterative, evolutionary process. My previous work on object-oriented design for resource allocation problem followed a systematic engineering approach to develop an object-oriented resource allocation model using the domain theory of scheduling, production rules approach and object-oriented technology. The architecture reflected in the software models and in the implementation used the traditional O-O approach of inheritance and clientsupplier relationships for system decomposition and interactions were mainly procedure calls. The software architecture in the above study was a box and line diagram and the connections between objects and components were not preserved explicitly. The study in progress recognises the importance of preserving the visibility between objects and components and addresses architectural issues to arrive at explicit reuse mechanisms. The interaction model between business rules and domain objects is being analysed and validate..
