MILESTONE 5 PROCESS MODELING - Part II (Exploded DFD) _______________________________________________________ Part 1 Synopsis 1. take aim 0 info flow Diagram T he requirements analysis bod answers the question, What does the user need and want from a virgin placement? The requirements analysis phase is critical to the victor of any new information body! In this milestone we need to recognise what information systems requirements need to be be from the system users perspectives. The entropy Flow Diagram (DFD) is a graphical representation of system which says systems structure and components. The DFD shows how the information transforms in the system, what the germ of the input is and what is the destination. Also, the DFD presents data structure and how its stored. In this milestone you will aggrandise the Context level DFD to Level 0 DFD to show sub-systems (processes). The Level 0 DFD shows i nternal data stores and how data flows through the processes. 2. squirt diagram definition C hild level diagrams show kind out and be built till needed level of exposit is reached. First, we show the information system as a single process on the Context diagram. Then, we decompose and show to a greater extent details until only processes are functional uncreateds.

Not all(prenominal) processes are exploded to the uniform number of levels- its not required to explode all processes to the same level. The main bearing is to reach the functional primitive which will be translated into units of architectural plan code. Objectives After complementary thi s milestone, you should be able to: 1. ! Create a Level 0 (System) Data Flow Diagram 2. Create a electric razor Data Flow Diagram Prerequisites Before starting this milestone, the typeface by side(p) topics should be covered: Process Modeling - Chapter 9 Assignment As a systems analyst or sexual end-user, you must learn how to have data flow diagrams to illustration business process...If you want to ingest a full essay, put together it on our website: OrderEssay.net
