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






2. __________________: written materials that accompany the system process






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






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






5. Flow Chart: data - input - output






6. ____________ Testing - testing conducted on a complete - integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing - and as such - should require no knowledge of






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






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






9. 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






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






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






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






13. Dtypically the riskiest method of systems conversion






14. Of input - output - processing - storage methods - and procedures - the one designed first by the analyst is _________






15. Flow Chart: comment






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






17. A flowchart represents an _____________ or process.






18. System testing is performed by ____________






19. ____________ 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






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






21. Flow chart: ____________ represents an event which occurs automatically. Such an event will trigger a subsequent action - for example 'receive telephone call' - or describe a new state of affairs






22. Describes the inputs - outputs - and processing logic for all program modules.






23. The configuration of the system document features and performance during the systems development process.






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






25. Flow Chart: a loop must begin with a _________






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






27. _________ Type of systems conversion where various capabilities are added to the system over a number of years






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






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






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






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






32. Documents the system at the end of the design phase and identifies any changes since the functional baseline.






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






34. Process of tracking system releases - or versions






35. A type of questionnaire which uses very explicit questions and require a short written response is called a(n) _________ _________ questionnaire






36. Type of system implementation that is used in its entirety only in one locality or area






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






38. 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






39. 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






40. Flow Chart: Processing steps - "process blocks" - an operation or action step






41. The most important skill or requirement of the analyst is good_________ skills






42. Measures a module's scope and processing characteristics






43. Flow Chart: Connector - continues a chart to another point on the same page






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






45. testing attempts to make a system ____________






46. ________________ - a document created by the systems project team that takes into account the organizational constraints and the personnel involved in using a new system.






47. Program testing is carried out by computer _________






48. The most significant output of the systems analysis phase of the entire analysis and design process is the _________ _________ _________






49. ____________ Testing: Another name for integration testing






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