Papa Sagacity School is a small private school that has retained your services as a systems analyst to assist in the development of a new information system for the school’s administrative needs. Background Your preliminary investigation and fact-finding tasks are complete. You join Papa Sagacity’s director, for a status update meeting to discuss the progress you have made with the requirements documents you put together. You discuss the system requirements and she is in agreement with you on what you have identified as necessary components of the new system. The new information system will contain components that will register students, generate drop-in reports, generate bills, record payments, generate receipts, and generate monthly reports. The next step is to develop a logical model of the proposed billing system. You explain to her how you will develop data flow diagrams (DFDs) that will be used to graphically show how data input will move through a system and be turned into useful information.

Tasks
1. Prepare a context diagram for the new system.
2. Prepare a diagram 0 DFD for the new system.
3. Prepare a list of data stores and data flows needed for the system. Under each data store, list the data elements required.
4. To help explain to Papa Sagacity the processes used to further develop the diagrams into the system model, write a brief memo that explains the importance of leveling and balancing a set of DFDs. Make sure the memo contains the proper formal heading and formatting
