1. Prepare a context diagram for New New Century’s information system.
2. Prepare a diagram 0 DFD for New Century. Be sure to show numbered processes p rocesses for handling appointment processing, payment and insurance p rocessing, report processing, and records maintenance. Also, prepare lower-level DFDs for each numbered process.
3 - Prepare a list of data stores and data flows needed for the system. Under each data store, list the data elements required. The data flows are as follows: Bill Drop-in Hours Drop-in Report Fixed Fees Payment Payment Data Receipt Receipt Data Registration Data Report Data Reports Student Data Variable Monthly Fees The Data Stores are as follows: Drop-In Data Registration Data here – Data Elements for each data store are as follows: (Note that answers may vary here – students should pick out all the data elements identified in Chapter 3 as existing, and should speak to new elements needed to create “family” bills. Drop-In Data Household Number Student Name Student Number Month Date of Attendance Block Attended Registration Data Household Number Student Number Student Name Monthly Fixed Fees Prepare a data dictionary entry and process p rocess description for one of the system’s functional primitives.
4 - Prepare a data dictionary entry and process description for one of the system’s functional primitives. Data Dictionary
The data flow diagram is used to represent the functional flow of the system. Though N ew Century system is very simple, there is no need o f making a logical solution complex, a new principle can be created using decision table or decision tree. A complete listing of the functional activities consisting of input and output data flows, hav e been arranged. Sample documentation of the above four processes identified in the 0-level diagram are mentioned below: PROCESS MAKE APPOINTMENT PURPOSE: Schedules a patients appointment and services.
