Chapter-5, System Development Process 1. While acquiring computer hardware, software, and specialists, which you think should be given the priority? cost/benefit analysis costs feasibility benefits 2. The mistake, committed by interchanging two digits in a numeric field; during data entry, is called Transposition error Transcription error Beta testing error Alpha testing error 3. The best file organization where one has to process all the data records in a file is Indexed Sequential Direct access Random access 4. In an organization, reliable hardware and software are available to implement a proposed system economic feasibility technical feasibility operational feasibility organizational feasibility 5. Structured design methodology is an approach to de¬sign that adheres to rules based on principles such as Top-down refinement Bottom-up design Data flow analysis All of these 6. During the maintenance phase System requirements are established System analysis is carried out Programs are tested None of these 7. To avoid errors in transcription and transposition, dur¬ing data entry, the System Analyst should Provide for a check digit Provide for a hash totals Provide batch totals All of these 8. Which of the following statement is true? Entity Relationship Diagrams are used to design files. Systems Overview can be prescribed by Data Flow Diagrams. Phases, in a Systems life cycle, are fixed and invariant. Only a programmer can conduct a system study. 9. The primary tool used in structured design is a Data flow diagram Module Structure chart Program flowchart 10.
