Bar Code Scanner Based Student Attendance System (SAS) for ✓ Solved

This assignment focuses on the Bar Code Scanner Based Student Attendance System (SAS) for an elementary school and covers the first three phases of the Software Development Life Cycle (SDLC): Planning, Analysis, and Design. Each of these phases includes necessary details, descriptions, and diagrams that illustrate the methodologies and findings.

Part 1: Planning Phase

In the Planning Phase, we will adopt a suitable Software Development Life Cycle (SDLC) methodology to guide the development process. For this project, the Agile methodology is selected due to its flexibility and iterative nature, which is ideal for developing software applications that may require adjustments based on user feedback.

To ensure effective project management, a Gantt chart has been developed to outline the work plan. This chart highlights the timeline for each phase of the project, including key milestones and deliverables. The Gantt chart serves as a visual representation of the project schedule, making it easier to track progress and adjust timelines as necessary.

Part 2: Analysis Phase

The Analysis Phase involves determining the main business requirements necessary for the SAS. This phase establishes a clear understanding of user needs and system functionality, which are crucial for the successful implementation of the attendance system.

Use Cases

Use Cases outline the interactions between users (students and teachers) and the system. They define the system’s functional requirements by describing how users will interact with the application. Key use cases for the attendance system include:

  • Student scans bar code to mark attendance.

  • Teacher reviews attendance records.

  • System generates attendance reports.

Process Modeling (Data Flow Diagrams)

Data Flow Diagrams (DFD) graphically represent the flow of data within the system, depicting how data moves from one process to another. In the attendance system, DFDs illustrate how attendance data is collected, processed, and stored.

Data Modeling (Entity-Relationship Modeling)

Entity-Relationship (ER) modeling is used to represent the data structures within the system. The ER model for the system includes entities such as Students, Teachers, and AttendanceRecords, along with their relationships. This modeling is vital for understanding the database necessary to support the application.

Part 3: Design Phase

In the Design Phase, the architecture of the SAS is selected, along with the user interface structure and class designs required for implementation.

Architecture Design

The architecture design for the system is structured using a client-server model. This approach allows for the separation of the user interface from data management, facilitating easier updates and maintenance.

User Interface Structure Design

The user interface design is critical for ensuring usability and user satisfaction. The screens must be intuitive and easy to navigate. Below is a conceptual design of the user interface:

Class Design Diagram

The Class Design Diagram provides insight into the object-oriented structure of the system. This diagram outlines the classes required, their attributes, and relationships. Classes might include Student, Teacher, and Attendance, each with their respective methods and properties.

Conclusion

This document elaborated on the steps taken through the Planning, Analysis, and Design phases of developing the Bar Code Scanner Based Student Attendance System. Each phase was carefully structured to ensure a comprehensive understanding of requirements, processes, and designs necessary to create a functional and user-friendly attendance management system.
