2.3 Data Flow

Describe how data moves through the system, including data sources, transformations, and destinations. Provide diagrams to illustrate data flow.

3. Detailed Design

This section delves into the specifics of each component, including algorithms, data structures, and interface specifications.

3.1 User Interfaces

Detail the design of user interfaces, including layout, navigation, and interaction patterns. Provide wireframes or mockups as necessary.

3.2 Data Storage

Describe the design of data storage solutions, including database schema, data models, and storage mechanisms.

3.3 Integration Points

Outline how the software integrates with other systems or services, including APIs, protocols, and data formats.

3.4 Error Handling

Detail the strategies for error detection, reporting, and recovery, including specific error messages and logging mechanisms.

4. Security Design

This section addresses security considerations, including data protection, authentication, and authorization mechanisms.

4.1 Data Protection

Describe measures for protecting sensitive data, including encryption and access controls.

4.2 Authentication

Detail the authentication methods used to verify user identities and secure access to the system.

4.3 Authorization

Explain the mechanisms for controlling user access and permissions within the system.

5. Performance Considerations

5.1 Scalability

Describe how the system is designed to handle increasing loads and user volumes.

5.2 Response Times

Specify the expected response times for key operations and interactions.

5.3 Resource Usage

Detail the resources required by the system, including memory, CPU, and storage.

6. Testing Strategy

Outline the approach for testing the software, including types of tests, test cases, and criteria for success.

6.1 Test Types

Describe the different types of tests to be performed, including unit tests, integration tests, and system tests.

6.2 Test Cases

Provide examples of test cases, including inputs, expected results, and execution steps.

6.3 Success Criteria

Define the criteria for determining whether the software meets the design specifications and requirements.

7. Documentation

This section specifies the documentation required for the software, including user manuals, technical guides, and maintenance documents.

7.1 User Documentation

Detail the documentation for end-users, including user guides and help files.

7.2 Technical Documentation

Describe the technical documentation for developers and maintainers, including code comments and design notes.

7.3 Maintenance Documentation
