Question

1.Describe the different phases of an application development cycle.

2.Explain how a program goes from source code to execution code.

Explanation / Answer

The phases in an application development cycle are: Gather requirements for the program, what the program is supposed to do -> Analyze the requirements -> Design the program from the requirements and figure out what the code is supposed to do -> test the code, identify bugs, revise them, and test the code again -> Deploy the code in a real system environment, to determine compatibility with the framework, and test it with real users -> Release the code for production into the market -> Maintain the code, fix bugs found in the code and release patches or updated versions of the software. http://publib.boulder.ibm.com/infocenter/zos/basics/index.jsp?topic=/com.ibm.zos.zappldev/zappldev_11.htm Source code is just code written in a programming language. C++ code, for example. Compilers take source code, and transform it into object code, which is basically machine code. This machine code is then "linked" together, using a linker, which binds them into an executable file.
