The systems development life cycle (SDLC), or software development life cycle systems engineering, information systems and software engineering, the process of creation or modification of systems and models and methods that people using these systems. The term generally refers to computer or information.
In software engineering the underlying concept of SDLC methodologies are many types of software development. These methods provide the framework for planning and control of the creation of an information system: the software development process.
Systems Development Life Cycle (SDLC) is a process used by the systems analyst for an information system, including requirements, validation, training development, and the user (stakeholder) property. Each SDLC should result in a high quality system that meets or exceeds customer expectations, within time and cost estimates, works effectively and efficiently in the current and future IT infrastructure, and is cheap to maintain and economic strengthening.
Computer systems are complex and often for any business analyst (particularly with the recent emergence of Service Oriented Architecture) linking traditional systems supplied by different vendors. To address these complexities, a number of SDLC models or methodologies are made, as the "waterfall", "spiral", agile, rapid prototyping, "incremental" and "sync and stabilize".
