Software Development Life Cycle, also known as "System
Design Life Cycle".
Software development life cycle for any project or
application is usually build or passed through some
sequential process which are termed as software development
Software development life cycle consists of four phases.
1.Analysis: Define the goals.Gathering the requirements to
develope a software for customer satisfaction.Aanalyse that
how to use and design?.
2.Design: Detailed design the requirements as a structure.
3.Implementation: Implement the detailed design with
4.Testing: Check the whether the software will work
properly or satisfies the customer expectation.
If it is satisfies the customer needs, that software
This is software development life cycle.

with the features of Prototype model and Waterfall model.
2.Spiral model takes special care about Risk Analysis.
Whreas it is not given importance in Prototype model.
Incremental life cycle model.
Generates software quickly.
More flexible and less cost to chane of requirements.
Easy to test and debug during iteration.
Easy to manage the risk.

Dvelopment Life Cycle. It consists of all the phases of a
s/w development. I can say that SDLC is the backbone of any
s/w development. If we want to develop an ideal s/w we must
follow any SDLC model. Without uisng any SDLC I think we
can not imagine the development of any S/W.
