MIS 7610 Systems Analysis and Design
Week 5 Assignment
Data Flow Diagramming ~ Process Modeling
Last week you had to think about the University of Memphis and create two separate sets of Use
Case diagrams; (1) for the University Registration System, and (2) for the Library Borrowing System. For this week’s assignment you are to create Data Flow Diagrams (level 0 and level 1) for both of those systems same two systems (Which are provided below). Don’t forget that you need to integrate the Use Case diagrams that you completed last week in the creation of your Data Flow Diagrams.
You can use the examples in your book as the guide on how to create Data Flow Diagrams. The internet is also a good resource for examples of Data Flow (process model diagramming).
Use Case Diagram: Online Registration System
When creating an online registration system there are various key factors that need to be implemented into the system. As a result, as per the online registration system, the following are the assumptions that the system will work with to enable students register themselves to the university as well as select their courses.
i. Professors will have an opportunity to indicate the courses they will teach online
ii. System allows students to print the course catalog
iii. Students can select a maximum of up to three course in one semester where the courses have a limit of three student and a maximum of ten students.
iv. Once the student has completed their registration, the system will automatically send the student’s information to the billing system.
v. Next, the professor will get the roster of the courses registered online.
vi. Finally, students will have one month after registration to add or drop any of the classes.
Use Case Diagram: Library Borrowing System
The library borrowing system is designed in such a way that it has a record of all books that are currently in the library shelves as well as who at any one point has borrowed which book and the due date. When a student goes to the library to borrow a book, they are required to present a valid ID card which will be checked by the librarian on the student database. In addition, the librarian ensures that the student does not have any overdue books or fines that are unpaid before they can borrow another book. If a book is overdue more than two weeks, a fine is imposed and the borrower informed on the fine imposed and reminded to return the book. In addition, if a book is return in a damaged condition, the manager will have to remove the books from the database and impose a fine to the borrower.
