📘Easy summary
Software development is a systematic process that transforms user needs into software products, through analysis, design, coding, testing and deployment. The Software Development Life Cycle (SDLC) is a framework that defines the processes used by organizations to build an application from its initial conception to its deployment and maintenance. Its primary purpose is to deliver high-quality software that meets customer expectations, reaches completion within time and cost estimates, and works efficiently. A framework is a standardized, reusable set of concepts, practices and tools that provides a structured foundation with predefined components and architectures (e.g. Django for websites).
⭐Key points
- SDLC: conception → deployment → maintenance.
- Goal: quality, on time, within cost.
- Framework = structured foundation with predefined components.
