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






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






3. ____________ 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






4. Testing of an individual program module.






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






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






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






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






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






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






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






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






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






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






15. 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






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






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






18. 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.






19. _________ The first procedure in a system test plan






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






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






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






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






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






25. _________ makes the final decision whether or not a system will be implemented






26. 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






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






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






29. __________ - analyst compares the expenses against the advantages of a system






30. Dtypically the riskiest method of systems conversion






31. HIPO Chart __________: extensive training/experience needed - uses top-down programming techniques - extra documentation requirements






32. Flow Chart: Decision/Conditional - a question or branch in the process






33. ________________ is an output of the systems audit






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






35. Used answer questions about specific scenarios that could potentially appear in a situation during capacity planning






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






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






38. testing attempts to make a system ____________






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






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






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






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






43. Flow Chart: data - input - output






44. Integration testing is also called ____________ testing






45. Process of tracking system releases - or versions






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






47. 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






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






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






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