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 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.






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






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






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






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






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






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






8. ____________ 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






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






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






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






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






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






14. A flowchart represents an _____________ or process.






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






16. ____________ 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






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






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






19. 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






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






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






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






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






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






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






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






27. Flow Chart: comment






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






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






30. Measures a module's scope and processing characteristics






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






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






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






34. 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






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






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






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






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






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. _________ The first procedure in a system test plan






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






42. testing attempts to make a system ____________






43. Integration testing is performed by ____________






44. When initially collecting data for a systems project - it should be collected via ________________






45. Program testing is carried out by computer _________






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






47. ________________ is an output of the systems audit






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






49. __________________: written materials that accompany the system process






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