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.

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






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






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






5. 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






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






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






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






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






10. Flow Chart shapes are similar to ________






11. 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.






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






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






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






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






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






18. Program testing is carried out by computer _________






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






20. During the design of input - the analyst establishes how to _________ _________






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






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 _________ conversion






23. 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






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






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






26. Dtypically the riskiest method of systems conversion






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






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






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






30. ____________ 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






31. Flow Chart: comment






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






33. System testing is performed by ____________






34. 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






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






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






37. ________________ is an output of the systems audit






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






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






40. testing attempts to make a system ____________
