Such rules will enable, for example, the determination of which object should be included in the model of the application, what are their appropriate attributes, and which level of details is needed in the system model. The project combines theoretical analysis based on ontological foundations, a comprehensive comparative analysis of the literature, and experimentation with test cases. A set of rules has been defined and tried on test cases. The plan is to develop a computerized environment to support object-oriented analysis that will incorporate the rules. In Systems Analysis Systems analysis for computer-based information system is the study of user information requirements and the relevant organizational setting.
Systems design is the creation of a plan for implementing the information system.
System design results in a technically-oriented description of the system to be constructed. The system is built, however, to satisfy the information requirements of users. These requirements are presented to the analyst in a non-formal way. To be used as the basis for forming a design of the system the non-formal requirements have to be described formally as a model of the application. This model is termed a conceptual model.
