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






2. 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






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






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






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






6. Integration testing is performed by ____________






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






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






9. Of input - output - processing - storage methods - and procedures - the one designed first by the analyst is _________






10. Measures a module's scope and processing characteristics






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






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






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






14. ____________ - 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






15. 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






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. testing attempts to make a system ____________






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






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






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






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






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






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






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






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






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






27. 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






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






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






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






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






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






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






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






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






36. ____________ Testing: Another name for integration testing






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






38. Flow Chart: data - input - output






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






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






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






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






43. 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.






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






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






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






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






48. ____________ 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.






49. Flow Chart: comment






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