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






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






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






4. A flowchart represents an _____________ or process.






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






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






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






8. 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.






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






10. ____________ 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.






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






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






13. Process of tracking system releases - or versions






14. Flow Chart: data - input - output






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






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






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






18. ____________ 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






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






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






21. ________________ is an output of the systems audit






22. ____________ - 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






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






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. Flow Chart: comment






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






27. _________ The first procedure in a system test plan






28. Integration testing is also called ____________ testing






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






30. Program testing is carried out by computer _________






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






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






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






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






35. 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






36. Dtypically the riskiest method of systems conversion






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






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






39. Measures a module's scope and processing characteristics






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






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






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






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






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






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






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