3. 3 High-level system reguirements

Answer 1

### 1. High-Level Architecture of a Student Management System

A Student Management System (SMS) can be designed using a multi-tier architecture to enhance scalability, maintainability, and performance. Below is a high-level architecture diagram and classes of components involved:

#### High-Level Architecture Diagram

**Client Layer:**
- Web Application (HTML/CSS/JavaScript)
- Mobile Application (iOS/Android)

**Presentation Layer:**
- Frontend Framework (e.g., React, Angular, Vue.js)
- APIs (RESTful or GraphQL)

**Business Logic Layer:**
- Application Server (e.g., Node.js, Django, Spring Boot)
- Services:
- Authentication Service
- Student Management Service
- Course Management Service
- Grade Management Service
- Communication Service (Notifications, Emails)

**Data Layer:**
- Database Management System (RDBMS like PostgreSQL/MySQL or NoSQL like MongoDB)
- Data Models:
- Students
- Courses
- Enrollments
- Grades
- Staff

**External Integrations:**
- Payment Gateway for Fees Payment
- Third-party Authentication (OAuth, etc.)
- Learning Management Systems (LMS)

### 2. Activity Model for Registering a New Student

The registration process can be visualized as an activity diagram that depicts the step-by-step workflow of registering a new student in the SMS.

#### Activity Model Steps

1. **Start Registration Process**
- User selects "Register New Student"

2. **Fill Registration Form**
- Input Required Information:
- Full Name
- Date of Birth
- Address
- Phone Number
- Email
- Course Selection

3. **Validate Input**
- Check for mandatory fields and format
- Display errors (if any)

4. **Submit Registration Form**
- User submits the form for processing

5. **Store Data in Database**
- System saves student data in the Students table
- Assign a unique Student ID

6. **Assign Courses**
- System assigns courses based on user selection

7. **Send Confirmation Email**
- System triggers an email confirmation to the student

8. **End Registration Process**

#### Activity Diagram

### 3. High-Level System Requirements

Here are three high-level system requirements for the Student Management System:

1. **User Management:**
- The system must support user registration, authentication (sign-up/sign-in), and role-based access control for students, staff, and administrators.

2. **Course and Enrollment Management:**
- The system must allow students to view available courses, register for courses, and manage their enrollment status. This includes the ability to drop or add courses within specified deadlines.

3. **Reporting and Data Analytics:**
- The system must provide reporting capabilities for generating statistics on student performance, course enrollments, and other relevant metrics. Users must be able to view and export reports in various formats, such as PDF and CSV.

These high-level requirements can further be broken down into more detailed functional and non-functional requirements during the requirement gathering and design phases.
