System Analysis And Design

Subject : it-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Documents the system at the end of the design phase and identifies any changes since the functional baseline.






2. Data Flow Diagram: each circle is identified by a ___________






3. Describes the system at the beginning of system operation.






4. A precise yet compact way to model complicated logic. Like if-then-else and switch-case statements - associate conditions with actions to perform. But - unlike the control structures found in traditional programming languages - they can associate man






5. Point where no changes can be made without impacting the schedule _________ _________






6. A technique for representing program logic that a systems analyst can use to describe program actions.






7. Program testing is carried out by computer _________






8. A _________ systems conversion takes place when the old system is switched off and the new one is started up.






9. ________________ is an output of the systems audit






10. The process for controlling changes in system requirements during software development.






11. A complete computer system will consist of people - _________ - hardware - software and data.






12. The most common reason for the failure of an information system is _________ _________ _________






13. Process that divides the overall objectives into subsystems and modules






14. A design approach where the system's analyst defines the overall objectives of the system - and then breaks them down into subsystems and modules.






15. Data flow diagram shape: process that transforms the data in some way






16. Data flow diagram shape: open ended (right) rectangle

19. The longest phase in the systems analysis and design process is the _______________ phase






20. testing attempts to make a system ____________






21. During the design of input - the analyst establishes how to _________ _________






22. This happens after completing integration testing - it involves the testing of the entire information.






23. In a program flowchart - a _________ ________ serves to fetch initial data item for processing






24. Process of tracking system releases - or versions






25. Applies to centralized batch processing operations - such as customer billing or credit card statement processing. It measures the time between submitting a request for information and the fulfillment of the request






26. _________ are the most reliable means of obtaining information about an existing system






27. Contains all the information needed for processing and distributing online and printed output






28. _________ Chart advantages: designs programs in testable models - creation of hierarchy of detail as design progresses - clear indication of necessary inputs and outputs






29. Data Flow Diagram: Circles will have data inflows and data ________________
