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






2. A flowchart represents an _____________ or process.






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






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






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






6. The analyst may solicit hardware and software proposals from vendors. The analyst will prepare a(n) _________






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






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






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






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






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






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






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






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






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






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






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






18. ____________ 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.






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






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






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






22. Flow Chart: A _________ must have two flow line coming out of it






23. testing attempts to make a system ____________






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






25. the process that monitors current activity and performance levels - anticipates future activity - and forecasts the resources needed to provide desired levels of service.






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






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






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






29. ____________ Testing: Another name for integration testing






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






31. _________is the most commonly used tool by analysts to graphically illustrate the flow of data through a system






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






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






34. 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






35. ________________ is an output of the systems audit






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






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






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






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






40. System testing is performed by ____________






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






42. Flow Chart shapes are similar to ________






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






44. 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.






45. 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






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






47. Dtypically the riskiest method of systems conversion






48. Flow Chart: Off-Page-Connector - continues a chart to another page






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






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