It’s a process of developing software for a particular business requirement. To Develop a system there will be a step-by-step process called system development life circle (SDLC).
System Development Life Circle
What is system analyzing?
It is the process of collecting and interpreting facts, identifying the problems, and decomposition of a system into its components.
Type of Analyst
Phases in SDLC
The preliminary study gives us a perfect picture of what actually the physical system is. The outcome of this phase is a system proposal including problem definition, background analysis, and alternative findings.
After the preliminary stage, the management should accept the proposal, and then a feasibility study with a cost-benefit analysis report and solve the problems and achieve the scope will be included. There are four main components of a feasibility study.
It defines who will use the system, what it will do, and when it will be used. This is the last stage of analysis, system concepts and methodologies will be included.
The system will operate interns of hardware, software, and network infrastructures. Forms, Reports, and databases, will be designed & design strategy will determine, and also GUI (Graphical user interfaces) will be designed in the 4th stage.
Coding or development of the given design coding will start in this phase. This is the longest & the most expensive phase of SDLC. Following three steps of coding
It checks whether the system is working properly. There are two forms of testing.
Program testing means testing the system by using accurate test data. System testing divides into 4 categories.
