(ii) Prototyping concept can be of great importance as well as can represent failures if not handle in an efficient way. List the possible benefits and limitations of this concept.
(c) In the System Implementation phased, there are four main conversion strategies that can be adopted or implemented. Conversion is the process of changing from old system to a new system.
(i) Explain the four ways or types of conversion.
