We refer to a systematic and structured approach used in the process of designing software systems. It encompasses a set of principles, practices, and guidelines that guide software designers and developers in creating a well-organized and efficient software solution. The main objectives of a software design methodology include:
- Problem Understanding: Clearly defining and understanding the problem or requirements that the software aims to address.
- System Architecture: Establishing the overall structure and organization of the software system, including the identification of components, their relationships, and the system’s high-level design.
- Modularity: Breaking down the software system into manageable and independent modules or components, making it easier to understand, develop, and maintain.
- Abstraction: Utilizing abstraction to manage complexity by focusing on essential details while hiding unnecessary intricacies.
- Reuse: Promoting the reuse of existing components, modules, or design patterns to enhance efficiency and maintainability.
- Scalability: Ensuring that the software design is flexible and scalable, allowing for future modifications and expansions.
- Documentation: Creating comprehensive documentation that outlines the design decisions, rationale, and guidelines for future development and maintenance.
- Verification and Validation: Incorporating processes to verify and validate the design, ensuring that it meets the specified requirements and is error-free.
