Extract of sample "UML Models and User Interface"

Names Professor Subject Date Use case diagram A use case diagram is an uml component that shows the interaction of the user with the system. The figure below shows how the users interact with class attendance system. It is used to in analysis phase in clarification and organization of system requirements The figures below show Use cases documentation of the system Log in/ out Use case description This use case is used to get into the system Primary actors Admin, student, instructor Secondary actors none Pre-conditions For one to log in, one must be registered as a user. The password and user name must match otherwise an error message will occur. Post-conditions User must have internet connection either Wi-Fi or 3g in order to access the system. Basic flow A user connects his/ her phone with internet. User opens the application where log in window pops up. User enters log in crecidentials. System checks the password and username provided, if they match the user access the application otherwise an error message is displayed. The user can log out once he/she is done using the system Alternate flows If a user forgets his/ her pass word, he/she clicks on forgot password link A window opens and the user is asked to enter his/ her email that was used in registration. A link is sent to the email provided, with a link to set a new password Exceptions If a wrong password or email is entered, an error message is displayed asking the user to re-enter again. View course taken Use case description This use case shows the course taken by student Primary actors Instructor, student Secondary actors Admin Pre-conditions For one to view course taken, he/she must have successfully logged into the system. Post-conditions One must have internet connection Basic flow A user logs into the system He/ she open view courses taken window. User views information on the courses offered Alternate flows none Exceptions One is not able to view the courses offered if he/she cannot be able to log into the system View student attendance Use case description A user can be able to view all attendance information about a student. Primary actors Instructor, Student Secondary actors admin Pre-conditions A user must be logged into the system successfully in order to view the attendance of a student Student must be registered for that course/ unit Post-conditions Availability of internet connection Basic flow Log into the system Open a student attendance window. Generate a report to show the attendance behavior or a student Print/ download the attendance report Alternate flows After login , open reports window Filter using /student ID /course ID/unit ID to generate a report Print/ download the attendance report Exceptions One cannot access this information if a user fails to log in successfully View class attendance Use case description This use case shows the attendance information for a whole class Primary actors Instructor , admin Secondary actors Student Pre-conditions A user must be logged into the system successfully in order to view the attendance of a class A class must be taking that course/ unit Post-conditions Availability of internet connection Basic flow Log into the system Open a student attendance window. Generate a report to show the attendance behavior of a class Print/ download the attendance report Alternate flows After login , open reports Filter using course/unit ID to generate a report Print/ download the attendance report Exceptions None Set Rules Use case description This use case allows the user to set attendance rules of a unit. The dos and don’ts in attendance Primary actors Instructor Secondary actors None Pre-conditions A user must be logged into the system successfully in order to set the rules to be followed. The rules must apply to all students Post-conditions Availability of internet connection Basic flow Log into the system Open an attendance rules window. Set the rules up Alternate flows None Exceptions None Get Notification Use case description This use case sends notification to students on their absence status. It shows the number of absenteeism of a student based on the allowed number of absenteeism allowed Primary actors Student Secondary actors None Pre-conditions A user must have provided an email or phone number to be able to get notification. The number of absenteeism allowed must be almost over Post-conditions Availability of internet connection Basic flow Log into the system Allow receive notification option in the application Alternate flows None Exceptions None Check in Use case description This use case allows a student to electronically sign attendance sheet. Primary actors Instructor , Student Secondary actors Admin Pre-conditions An n instructor must open the application n his/her phone. A student must have a student card that is NFC enabled A student must be registered for that course/ unit Post-conditions Availability of internet connection Basic flow Instructor Logs into the system A student enters the class room and swaps his/her ID on instructor mobile Device. All data including attendance time are recorded Data is the stored in the database where it can be retrieved in future Alternate flows None Exceptions The system gives an error message when a student tries to us an ID that is not NFC enabled Activity diagram An activity diagram is used to show the workflow of a system. It shows step by step flow of activities (Stevens and Pooley). The figure below shows an activity diagram for a class attendance system. Sequence diagram is am UML diagram that depicts how process interacts with one another and the order in which they occur. The figure below shows a sequence diagram for this system How student interacts with the system sequence diagram Domain model diagram Component diagram A component diagram plays an important role in system development design as it is used to depict structural relationship on the components of a system. Boxed figures are used to represent the components while communication association is represented using dependencies. The figure below shows a component diagram Entity relationship The figure below shows an entity diagram for the student attendant system.
