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. Describes the system at the beginning of system operation.






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






3. ____________ - 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






4. Integration testing is also called ____________ testing






5. Program testing is carried out by computer _________






6. the process that monitors current activity and performance levels - anticipates future activity - and forecasts the resources needed to provide desired levels of service.






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






8. __________________: written materials that accompany the system process






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






10. 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






11. testing attempts to make a system ____________






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






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






14. ____________ 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






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






16. Flow Chart: comment






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






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






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






20. 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.






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






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






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






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






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






26. A flowchart represents an _____________ or process.






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






28. Measures a module's scope and processing characteristics






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






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






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






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






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






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






35. Type of system implementation that is used in its entirety only in one locality or area






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






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






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






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






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






41. System testing is performed by ____________






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






43. 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






44. Process of tracking system releases - or versions






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






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






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






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






49. ____________ Testing: Another name for integration testing






50. ____________ 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
