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 data inflows and data ________________






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






3. A _________ systems conversion takes place when the old system is switched off and the new one is started up.






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






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






6. Program testing is carried out by computer _________






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






8. ____________ Testing: Another name for integration testing






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






10. Flow Chart: data - input - output






11. Flow Chart: comment






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






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






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






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






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






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






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






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






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






21. testing attempts to make a system ____________






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






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






24. 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






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






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






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






28. 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.






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






30. Flow Chart shapes are similar to ________






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






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






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






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 parallel conversion






35. Measures a module's scope and processing characteristics






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






37. Process of tracking system releases - or versions






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






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






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






41. ____________ 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






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






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






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






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






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






47. Integration testing is performed by ____________






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






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






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