List and briefly describe each activity of the SDLC core processes Build, test, and integrate system components and Complete system tests and deploy solution

Build, test, and integrate
- Program the software – the programmers write the code
- Unit test the software – the programmers test the code they have programmed
- Identify and build test cases – this requires both project staff and end users. There are often test cases to be used for integration and system test. Additional end user test cases, which uses or simulates live data, are usually more complex.
- Integrate and test components – as components successfully pass unit test, they are integrated into a growing overall system and tested as part of the integrated system.

Complete system tests and deploy solution
- Perform system and stress tests – after the components are integrated successfully, then the entire system is tested to test cross functions, cross time periods, and high volumes.
- Perform user acceptance tests – user tests must be done with many kinds of test data, testing both good and bad situations, and verifying all use cases.
- Convert existing data – if the new system replaces an existing system valid data, such as customer accounts, must be converted to the new database format.
- Build training materials and conduct training – often end user training and perhaps system training is require to ensure that the deployed system runs successfully and that the users can do their work.
- Configure and set up production environment – the production environment must integrate with the existing technology and application architecture
- Deploy the solution – install the system on the production servers with the production database and begin using it.
