3. Implementation / Codding:

   in this phase the the overall work is divided into small modules and a team of coder and developers start to code the software.this is the longest phase of SYSTEM DEVELOPMENT LIFE CYCLE.

4. Testing:

   after complete the codding phase the product or software test make by applying different input and check the output.If the software is work correctly as requirements then it is ready for Deployment

5. Deployment:

   After successful testing the product is deliverable to the customer for their use.

6. Maintenance:

   the customer start to use product if there is any error or any extra functionality required to must be included, in this phase the developer update that functionality.Solve the problems and bugs are also maintain in this phase.
