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. Integration testing is performed by ____________






2. 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.






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






4. Graphical representations of workflows of stepwise activities and actions with support for choice - iteration and concurrency. Extension of flowchart.






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






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






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






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






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






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






12. testing attempts to make a system ____________






13. 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






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






15. Dtypically the riskiest method of systems conversion






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






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






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






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






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






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






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






23. 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






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






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






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






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






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






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






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






31. Flow Chart: comment






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






33. Program testing is carried out by computer _________






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. The first step in solving a problem with a computer






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






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






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






39. Flow Chart shapes are similar to ________






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






41. Testing of an individual program module.






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






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






44. System testing is performed by ____________






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






46. Process of tracking system releases - or versions






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






48. 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






49. A flowchart represents an _____________ or process.






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