QR Code Attendance System Use Case Diagram
The capstone project, “QR Code Attendance System with SMS Notification” is designed to systematize the attendance system in school. The attendance system will be based on QR codes scanned by students in entering and leaving the school premises. Upon the recording of attendance, the system will generate SMS to notify the parents about the arrival and departure of their children in school. The QR Code Attendance System is a new way to take attendance for classes and events. It uses a QR code that is scanned by a smartphone to take attendance. This system is beneficial because it is quick and easy to use. It is also more accurate than traditional methods, such as taking attendance by hand.
Core features of the QR code student attendance system will focus on time-in/out for attendance, student information encoding, SMS notifications, QR code generation, and scanning reports generation, and database backup.
What is Use Case Diagram?
Table of Contents
The Unified Modeling Language (UML) defines a specific sort of behavioral diagram called a use case diagram that demonstrates how users, often referred to as actors, interact with a system. It is useful to first comprehend the many kinds of interactions that users may have with a system before designing or documenting it. Use case diagrams, which represent these interactions as a collection of use cases, which are particular illustrations of how users might engage with the system, capture these interactions.
The benefits of using Use Case Diagrams include:
- It is beneficial to define the various kinds of user interactions with a system and give examples of such interactions. By doing so, it may be possible to enhance the system’s design and gain a better understanding of how people would probably interact with it.
- It can help to create system architecture for a system. By understanding how users will interact with the system, it can be easier to design the appropriate components and systems for that system.
- It can help to identify areas of improvement or potential enhancements for a system. By understanding which interactions are most commonly used by users, it can be easier to focus on those areas in order to improve the overall usability of the system.
- When a system is implemented or used, it can assist in avoiding potential issues. It may be simpler to see any issues that may come up during installation or use if one is aware of how people are likely to interact with the system.
- It can be applied to the development of a system’s requirements document. It may be simpler to decide what features and functionality are needed by recording all of the many user interactions that may occur with the system.
Overall, Use Case Diagrams are a valuable tool that can help to improve the design and usability of a system. They should be used whenever possible, in order to ensure that the system is designed correctly and meets the needs of its users.
