Study Notes
Design Phase Overview
- Development of a Design Document Specification (DDS) using the Software Requirements Specification (SRS).
- The DDS acts as a blueprint guiding the implementation process for the development team.
- Thorough review of the DDS by stakeholders is essential for alignment with project goals.
Objectives of the Design Phase
- Define System Architecture: Establish the overall structure, including front-end (web application), back-end (server), and database components.
- Detail Component Design: Specify functionality and interaction of components; front-end utilizes React.js, back-end employs Node.js, and the database is MySQL.
- Create Interface Designs: Develop layouts for user interfaces including a login screen, dashboard, and settings page.
- Develop Data Models: Outline data storage and manipulation; user data stored in a user table with fields such as name, email, and password.
- Establish Security Measures: Plan security protocols; passwords are hashed and secured with bcrypt encryption.
Creating the DDS
- The DDS serves as a central output from the design phase, guiding developers during implementation.
- Clarity in the DDS helps ensure understanding among all project participants regarding software functionality and structure.
Components of a DDS
- System Architecture: Overview of hardware, software, and network structure; hosted on AWS with traffic managed by a load balancer for multiple EC2 instances.
- Detailed Design of Modules: Specifications covering inputs, outputs, and processes for each module; user authentication module verifies credentials against the database.
- Interface Design: Includes layouts and descriptions for user interfaces and APIs; the dashboard interface displays real-time analytics via charts and graphs.
- Data Design: Models database schemas and data flows; includes tables for users, products, orders, and payments.
- Security Design: Details security protocols; uses HTTPS encryption for data transmission and implements role-based access control.
Reviewing the DDS
- Stakeholder review of the DDS is crucial to ensure it meets project requirements and constraints.
- The review process should be comprehensive, covering all design aspects.
Criteria for DDS Review
- Completeness: Confirm all SRS requirements are addressed; includes all specified features and functions.
- Accuracy: Ensure correct implementation of requirements; data models and interfaces meet specified needs.
- Feasibility: Assess if the design can be implemented within constraints such as time, budget, and technology.
- Consistency: Check for coherence throughout the document, ensuring no conflicting information is present.
