Software Development Life Cycle, SDLC for short, is a well-defined, structured sequence of stages in software engineering to develop the intended software product.

Software life cycle models describe phases of the software cycle and the order in which those phases are executed. Each phase produces deliverables required by the next phase in the life cycle. Requirements are translated into design.


Phases of Software Development Life Cycle Modle
Requirement gathering and analysis
Design
Implementation or coding
Testing
Deployment
Maintenance

) Requirement gathering and analysis: Business requirements are gathered in this phase. This phase is the main focus of the project managers and stake holders. Meetings with managers, stake holders and users are held in order to determine the requirements

) Design: In this phase the system and software design is prepared from the requirement specifications which were studied in the first phas

3) Implementation / Coding: On receiving system design documents, the work is divided in modules/units and actual coding is started.

) Testing: After the code is developed it is tested against the requirements to make sure that the product is actually solving the needs addressed and gathered during the requirements phase.
5) Deployment: After successful testing the product is delivered / deployed to the customer for their use.

6) Maintenance: Once when the customers starts using the developed system then the actual problems comes up and needs to be solved from time to time.
