Understanding Requirements

Defining requirements is the foundational step in system design. It involves identifying what the system needs to achieve, considering various stakeholders' needs.

• Functional Requirements: These describe what the system should do, such as user authentication or data processing.
• Non-Functional Requirements: These are related to the system's operation, like performance, scalability, and security.
• Constraints: These are limitations within which the system must operate, such as budget, technology, or regulatory compliance.

Gathering Requirements

The process of gathering requirements involves interacting with stakeholders to understand their needs and expectations.

• Interviews: Conducting interviews with users and stakeholders to gather insights.
• Surveys: Distributing questionnaires to collect data from a larger audience.
• Workshops: Organizing collaborative sessions to brainstorm and document requirements.

Functional Requirements

• User Registration: Users must be able to register and create an account.
• Product Search: Users should be able to search for products by category or name.
• Order Processing: The system should handle order placement, payment, and confirmation.

Non-Functional Requirements

• Scalability: The system should support a growing number of users without performance degradation.
• Security: Sensitive data, such as payment information, must be securely stored and transmitted.
• Availability: The system should have high uptime, especially during peak shopping seasons.

Functional Requirements

• Profile Management: Users can create and edit their profiles.
• Content Sharing: Users should be able to post text, photos, and videos.
• Friend Connections: Users can send and accept friend requests.

Non-Functional Requirements

• Performance: The platform should load quickly and handle large volumes of data efficiently.
• Usability: The interface should be intuitive and easy to navigate.
• Reliability: The system should maintain consistent performance and recover from failures swiftly.

Functional Requirements

• Patient Records: The system should manage and store patient medical histories.
• Appointment Scheduling: Patients and doctors should be able to schedule and manage appointments.
• Billing: The system should handle billing and insurance claims processing.

Non-Functional Requirements

• Compliance: The system must comply with healthcare regulations like HIPAA.
• Data Integrity: Patient data must be accurate and consistent across the system.
• Interoperability: The system should integrate with other healthcare systems and devices.

Functional Requirements

• Real-Time Data: Provide real-time market data to users.
• Trade Execution: Users should be able to place and execute trades efficiently.
• Portfolio Management: Users can track and manage their investment portfolios.

Non-Functional Requirements

• Latency: The system must have low latency to ensure timely trade execution.
• Security: Protect user data and transactions from unauthorized access.
• Scalability: Support a large number of concurrent users and transactions.

Functional Requirements

• Course Management: Instructors can create and manage courses.
• Student Enrollment: Students should be able to enroll in courses.
• Assessment: The platform should provide tools for quizzes and exams.

Non-Functional Requirements

• Accessibility: Ensure the platform is accessible to users with disabilities.
• Performance: The system should handle high traffic during peak usage times.
• Security: Protect user data and course content from breaches.
