DFDS are used to discuss with the user a diagrammatic interpretation of the processes in the system and clarify what is currently being performed. However, many errors may occur when drawing DFDS. a) You are requested to prepare a checklist that may help you avoid some of the major difficulties when developing DFDS.

As an independent consultant, you have a contract with a university to develop an application to support course administration. Read the detailed description of this application and then complete the tasks that follow. A course has a unique course number and title and is assigned to one or more areas of the Computer Science program. Each course has an instructor, at least one teaching or research assistant, an online discussion forum, a delivery period (start date, end date), and a capacity (maximum number of participants). A course need not be offered each term, but the challenge option is open throughout the entire year. A course may have prerequisite courses, and a student is not allowed to register for a course if they have not fulfilled the prerequisites or their equivalent. In addition, a student who would like to challenge a course should have the course prerequisites or authorization from the course instructor. An instructor has an employee number, first name, last name,…
