IS581 Milestone 11&12

IS581 Milestone 11&12 . Process modeling is a technique for organizing and documenting the structure and flow of data through a system’s processes and/or the logic, policies, and procedures to be implemented by a system’s processes. In this milestone, we focus on using and constructing data flow diagrams (DFDs) and decomposition diagrams to perform process modeling. Data flow diagrams are tools that depict the flow of data through a system and the work or processing performed by that system. A decomposition diagram is a DFD planning tool that shows the top-down functional decomposition and structure of a system. During this milestone, you will first construct a context diagram to establish project scope and boundaries. Secondly, you will draw an event decomposition diagram to partition the system into logical subsystems and/or functions. Thirdly, you will draw event diagrams to model individual processes. Finally, you will construct a system data flow diagram that shows the big picture of the system, and a primitive data flow diagram for a single event process.
