System Analysis and System Requirements Object Modeling, Process Modeling, and Strategies for System Analysis and Problem Solving April 6, 2005 Object Modeling A class can be described as a collection of objects of similar type. These objects often share the same attributes, operations, methods, relationships, and semantics. Additionally, once a class is defined any number of objects can be created and associated to that class. For example, beagles and boxers represent different breeds (i.e. instances) of "dogs" which also can be viewed as a distinct class. Furthermore, defining classes, as part of the object modeling process is not that different from the traditional system analysis process, which seeks to achieve a goal (i.e. …show more content…

In addition, to organizing the flow of data throughout a system, logical models also provide means of bridging the gap of communicating information to end-users in a non-technical manner while also preserving the requirements. Finally, logical models encourage creativity and reduce the risk of missing requirements, which are normally missed because of pre-occupation with technical details. Like the logical processing model a context data flow diagram defines the scope and boundary for the system and project. Because the scope of any project is always subject to change; the context diagram is also subject to constant change. A context diagram is referred to as being another representation an environmental model. Finally, the initial project scope can be defined using a context diagram. A project's scope is important in that it defines what aspect of the business a system or application is supposed to support. An event diagram represents the final area of my discussion of the Process Modeling method. An event diagram represents a context diagram that focuses on the inputs, outputs, and data store interactions for a single event. In addition, most event diagrams are also representative of a single process, which can be referenced back to the event identified for a decomposition diagram. Event diagrams therefore are valuable for identifying and addressing event driven factors, which when combined with other
