Q2) Describe what decomposition is used for.
Answer: Decomposition results in smaller pieces of a system which are then easier to work with. This is accomplished by breaking a system down into smaller components. Decomposition allows the systems analyst to focus attention on one area of the system, focus on one part of the system pertinent to a group of users and build parts of the system independently.
Q3) During logical design, the analyst team decides which programming languages the computer instructions should be written in, which database systems and file structures will be used for the data, and which hardware platform, operating system, and network environment the system will run under.
