Computer Science Question

A data flow diagram (DFD) shows how information flows within an information system. A DFD is a representation of the data flow and does not imply the activity order. A DFD is a model of a real-world business system represented through a hierarchy of abstracts through leveling. Lower levels of a DFD reflect more detail, and higher levels of a DFD reflect less detail. A logical system diagram describes the business events that take place and the data required for each business event, focusing on what information is flowing and what information is transmitted. A DFD will not go into technical (hardware and software) aspects of the system; it will show inputs and outputs from external sources, showing the path of data and how it flows through the system. For this activity, you need to create a data flow diagram reflective of the following: Your DFD must include the listed processes and at least two subprocesses (levels) within two of the five main processes. Your diagram can reflect up to three levels: zero (the context diagram), one (subprocess), and two (functionality). The various levels of detail are: Use the symbols from the Gane and Sarson symbol set needed to illustrate data flow within your diagram: Specifically, you must address the following rubric criteria: Data Flow Diagram: Your diagram must be completed without any missing components. It needs to show how information flows within a system process. Remember: only DATA flows on data flows. Hierarchical Leveling: Whether your diagram has one or three levels, it needs to illustrate how each level is broken down into smaller business events. Data Flow Notation: Your diagram should include accurate and appropriate data flow notation. Whenever you are referring to a process, use a rounded square symbol. Whenever you are referring to data that is being stored, use a rectangle. It depends on the business process, but you may or may not have to use all Gane and Sarson symbols. Logical System Functionality: Your diagram also needs to illustrate how business events are broken down into smaller subprocesses. Upload a .doc, .pdf, or .jpeg file of your diagram. You can use a tool of your choice to help you create the data flow diagram Requirements: Create a diagram and include everything in the diagram that’s mentioned within the prompt Your experience registering for a course and then following the process through payment (or using financial aid).
