Study Notes
Software Development Life Cycle (SDLC)
- The purpose of SDLC is to develop software in a structured and organized manner.
- The development team starts working in the SDLC process from the very beginning, defining and documenting the software architecture.
Software Architecture in SDLC
- Software architecture serves as a blueprint for the entire software system, providing a high-level view of the system.
- Software architecture provides a clear understanding of the system's components, interactions, and relationships.
- It primarily focuses on the overall structure and organization of the system during the design phase of SDLC.
- The main role of software architecture is to provide a roadmap for the development team, ensuring that the system meets the required quality attributes.
Quality Attributes in Software Systems
- Scalability refers to the ability of a system to adapt to increased workload, users, or data without compromising performance.
- Reliability refers to the ability of a system to perform its intended functions without failure or error.
- Availability refers to the ability of a system to be accessible and usable when needed.
- Maintainability refers to the ease with which a system can be modified, repaired, or upgraded.
- Security refers to the ability of a system to protect itself and its data from unauthorized access or malicious attacks.
- Performance measures the responsiveness and efficiency of a system in completing tasks.
- Testability refers to the ease with which a system can be tested and validated.
Importance of Software Architecture
- Software architecture plays a crucial role in enabling the selection of quality attributes and optimizing them for a system.
- It allows for modifications without affecting the entire system by incorporating adaptability into the architecture's design.
- A well-designed software architecture provides a solid foundation for the entire system, ensuring that it meets the required quality attributes and performance expectations.
