Defining SDLC
A software development life cycle, also known as a software development process, is a methodology used for the development of a software product.
There are several methodologies for such processes, each method accomplishes software development by using different tasks or activities that take place during the software development process.

When to used the Waterfall Methodology
Well defined requirements
Stability of production definition
Technology is understood
Upgraded version of an existing software
Porting existing software to a new platform
V-Model Methodology
A modification of the
Waterfall that verifies and validates the software.
Product testing is done in parallel at each phase of development V-Model Methodology Stages
Specify requirements
Acceptance test
Outline design
System Test
Detail design
Integration Test
Code and Unit Test
When to use the V modelMethodology
Appropriate for systems requiring superior reliability
Software requirement are identified upfront
