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






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






3. 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






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






5. ____________ - 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






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






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






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






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






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






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






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






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






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






15. A flowchart represents an _____________ or process.






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






17. Integration testing is also called ____________ testing






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






19. Dtypically the riskiest method of systems conversion






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






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






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






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






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






25. _________ The first procedure in a system test plan






26. ____________ 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






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






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






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






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






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






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






33. ____________ 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






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






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






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






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






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






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






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






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






42. ____________ 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.
