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: Circles will have numbers and ____________






2. A chronological listing of financial transactions is called a _________ _________






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






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






5. __________________: written materials that accompany the system process






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






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






8. Testing of two or more programs that depend on each other.






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






10. 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.






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






12. Flow Chart: data - input - output






13. 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






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






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






16. Testing of an individual program module.






17. Integration testing is performed by ____________






18. Flow Chart: comment






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






20. ____________ - 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






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






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






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






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






25. System testing is performed by ____________






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






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






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






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






30. 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






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






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






33. Dtypically the riskiest method of systems conversion






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






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






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






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






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






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






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






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






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






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






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






45. testing attempts to make a system ____________






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






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






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






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






50. 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
