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






2. Flow Chart: Preparation: any process step that is a preparation such as a setup operation






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






4. _________ The first procedure in a system test plan






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






6. ________________ is an output of the systems audit






7. In most cases - a request for computer services should originate from the _________ of the requested system






8. A method used by the analyst to document the scheduling of the completion of the project is a(n) _________ Chart






9. Type of Chart: uses flow lines and process blocks






10. Data Flow Diagram: Circles will have numbers and ____________






11. The overall time between a request for system activity and the delivery of the response






12. Flow Chart: comment






13. ____________ Testing - (sometimes called Integration and Testing - abbreviated "I&T") is the phase in software testing in which individual software modules are combined and tested as a group. It occurs after unit testing and before system testing.






14. testing attempts to make a system ____________






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






16. Flow Chart shapes are similar to ________






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






18. Flow Chart: Always has one flow line in and one flow line out - _________ symbol






19. The first step in solving a problem with a computer






20. Flow Chart: Represents start or stop/end. Pill shape (sometimes circle - oval - cigar or rounded rectangle)






21. The process of examining a program design and reviewing the logic of a program with test data






22. Dtypically the riskiest method of systems conversion






23. A chronological listing of financial transactions is called a _________ _________






24. When all non-critical changes are held until they can be implemented at the same time.






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






26. When it is too expensive to convert a system's old files and applications - a _______________ systems conversion is commonly used.






27. Data Flow Diagram Shape: open ended (right) rectangle






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






29. Which analysis and design tool used by the computer system analyst shows the levels and subdivisions of a computer system? _________ _________






30. Data Flow Diagram: in reviewing each circle - the analyst will find it yields a _______________






31. __________________: written materials that accompany the system process






32. ____________ Testing - The first procedure in a system test plan - a software verification and validation method in which a programmer tests if individual units of source code are fit for use. A unit is the smallest testable part of an application. I






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






34. ____________ Testing: the testing of a collection of units that have a logical relationship or flow from the user's perspective.






35. OLD: The total time required for an entire systems analysis and design process to be completed will most likely be _________ _________.






36. ____________ - a method for converting a manual system to an automated system whereby both systems are run simultaneously - whereupon the results are compared and the new system is phased in is called parallel conversion






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






38. A method for converting a manual system to an automated system whereby both systems are run simultaneously - whereupon the results are compared and the new system is phased in is called _________ conversion






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






40. Graphical representations of workflows of stepwise activities and actions with support for choice - iteration and concurrency. Extension of flowchart.






41. _________ accounts for the greatest expenditure involved in the cost of creating and maintaining a system.






42. 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






43. Describes the degree of interdependence among modules. (loosely coupled modules are desirable as they are more independent)






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






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






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






47. A design that can be broken down into logical blocks - also known as partitioning - or top-down design. This approach is similar to constructing a leveled set of DFDs.






48. The environment that analysts and programmers use to develop and maintain programs






49. Measures a module's scope and processing characteristics






50. Describes the system's functions and how they are implemented
