Lecture 7 object-oriented approach to requirements nov 2. The unified modeling language and the object management group. Object-oriented modeling notation is unified modeling language (uml) Uml was presented to object management group (omg) as standard modeling technique. Purpose of object management group: promote theory and practice of object technology for development of distributed systems, provide common architectural framework for oo. Object-oriented system requirements are specified and documented through. Systems development process starts with identification of events and things. Events are business processes that new system must address. Things are problem domain objects involved in business process. Class diagram definition of system components. Use case diagrams and use case descriptions what are user roles and how they use the system. Systems sequence diagrams (ssds) define inputs and outputs and sequence of interactions between user and system for a use case. State chart diagrams describe states of each object.
