In this class we focused on the implementation and maintenance phases of SDLC. When implementing a system you first need to acquire the hardware, software, and services needed to run the system. Then you need to modify your software, test the program, convert the data, and train the end-users of the system how to operate it.
After implementing your system you need to maintain it. System maintenance is done by fixing the bugs and errors, adding new functions, improving its performance, and preventative maintenance to keep the system from failing.
