System development life cycle(SDLC) is also known as application development life cycle.It is an Iterative process.This term is used in systems engineering, software engineering and information systems.
It has 5 phases.They are:
1)Planning
2)Analysis
3)Design
4)Implementation
5)Maintenance
1)PLANNING PHASE:
This first phase is to find out the scope of the problem.Resources,time,cost,etc of the project should be considered here.
2)ANALYSIS PHASE:
In this step,system analysis takes place.It analyses the needs to ensure the new system meet their expectations.
3)DESIGN:
It's during this phase that they will consider the essential components (hardware and/or software) structure (networking capabilities), processing and procedures for the system to accomplish its objectives.

4)IMPLEMENTATION:
Both system analysts and end-users should now see the realization of the project that has implemented changes.
5)MAINTENANCE:It involves continuous
Maintenance is an important aspect in SDLC. It involves continuous evaluation of the system in terms of its performance.
