Answer 1

16) a) Paas. Platform as a service allows users to access hardware and software provided as a complete platform to be used over the cloud by the provider of cloud computing services.

17) a) Parallel design. This strategy allows both systems to run in parallel facilitating a gradual transition with easy identification of even minor errors and deviations through adequate performance analysis.

18) a) To use multiple tables. To use a single table may be possible for some analysis but it greatly restricts the level and type of information and analysis that can be conducted to arrive at accurate inferences and results without any bias and with required level of confidence in the accuracy provided by multiple tables For eg., only sales column can provide an analysis for the sales performance of different periods facilitating adequate comparison and decisions focused on this single factor which can provide a one-sided picture. However, if a deeper analysis is required the cost, the profits, the time, and the conversion rate with comparison against promotional expenses and other periods performance also for comparison of products.

19) d) The direct design or direct cutover approach utilizes the strategy of absolute replacement of the old system with the new providing the dual benefits of lower cost and minimal time investment to make the transition but can be ineffective if the new system is not optimally designed to meet all requirements efficiently.

20) a) Business Analytics is the tool used by managers in organizations for prediction and analysis for informed decision making. It uses business intelligence for achieving this along with the application of other tools.
