How do the structured analysis and the system development life cycle method differ?
The software development life cycle (abbreviated as SDLC) consists of several phases. Different people use variations but the basic SDLC consists of system analysis, system design, coding and unit test, and them system testing. What is contained in each phase is I hope obvious. Structured analysis (and design) are methods that are employed during the system analysis (and system design) phase(s) to provide an error reduced system.
