(b) i-C, ii – D, iii-E, iv – A, v- B (c) i-A, ii – D, iii-B, iv – C, v- E (d) i-D, ii – A, iii-E, iv – B, v- C (e) i-B, ii – A, iii-D, iv – C, v- E.
(a) Analysis phase (b) Design phase (c) Feasibility study phase (d) Implementation phase (e) Maintenance phase. Answers:
Reason: Transactions produce loads of data everyday and Transaction processing systems aim at improving the routine business activities.
Reason: Prototyping is adopted if information requirements are not well-defined.
Reason: structured programming means splitting the overall task into well-defined subtasks.
Reason: Third party enquiry is not a technique to capture the requirements of the user.
Reason: All the given questions are useful in evaluating the DFDs.
Reason: extensive use of GOTO leads to spaghetti code.
Reason: data dictionary is for storing data about data where as data store is where actual data is stored .
Reason: After matching the both sides the correct option is (b).
Reason: During the Feasibility study the financial feasibility is also measured What are the three parts of a system vision document?According to the business management studies, there are three parts of the system vision document which are the description of the problem, benefits of the business through the project along system capabilities.
What do we call the type of testing that the users perform to ensure that the system meets the business requirements?Beta/User Acceptance Testing (UAT) — This is performed by the end-user to ensure that the system meets their business requirements. Business requirements define what an application should do but not how it should be done.
What is the difference between system capabilities and business benefits?What is the difference between system capabilities and business benefits? System capabilities: required capabilities of a new system; part of a system vision document. Business benefits: the benefits that accrue to the organisation; usually measure in dollars.
What is a system vision document?The System Vision Document is a brief statement which describes the overall objective of the new system. Its purpose is to provide basic information about the need and solution approach to assist the client in deciding whether to approve a development project.
