System Development Life Cycle (SDLC) is a common methodology for System Development
...
In any SDLC
phase, the project can return to an earlier phase, if necessary
...


We can also consider Life Cycle as a circular process in which the end of one phase leads to the
beginning of another phase that will develop a new version of the system
...
These are:
1
...

3
...

5
...


Project identification and Selection
Project Initiation and Planning
Analysis
System Design (Logical Design and Physical Design)
Implementation
Maintenance

Now Let us take each Phase one by one what each phase says about SDLC means describes
about SDLC
...
In this
Phase the user identifies What is the scope of project and how much to spend on the project
...
In this phase problems that are
identified should be investigated
...
He also decides
what activities to follow and who will do what, what sequence of activities need to follow
...
This phase has several sub-phases
...

In this phase, feasibility study of the proposed system is also performed
...

System Design
After the end of the analysis phase, design of the system begins
...
Logical Design: - In this design phase of the SDLC the process continues to move from
what questions of analysis phase to how
...
Physical Design: - In this design phase, the Logical Design changes into
the physical design
...

In the System design stage, the programming language, hardware and software platform in which
the new system will run are also decided
...
During this phase we turn system
specifications into a real and working system
...

We can install the system different ways such as Directly Installing the system at user's site,
Install it module wise, and keeping both old and new system run together
