    tests the performance of the information system as a whole
  28. Acceptance testing
    provides the final certification that the system is ready to be used in a production setting
  29. Parallel conversion strategy
    both the old system and its potential replacement are run together for a time until everyone is assured that the new one functions correctly
  30. Direct cutover conversion strategy
    replaces the old system entirely with the new system on an appointed day, carrying the risk that there is no system to fall back on if problems arise
  31. Maintenance
    changes in hardware, software, documentation, or procedures to a production system to correct errors, meet new requirements, or improve processing efficiency
  32. Problems without a formal development methodology
    specifically you are testing and documenting formed, formed rapidly
  33. Managing end-user development
    allows endusers, with little or no formal assistance from technical specialists, to create simple information systems, reducing the time and steps required to produce a finished application

    establishing standards for project requirements
  34. RAD
    Rapid application development: the process of creating workable systems in a very short period of time
  35. Data flow diagram
    offers a logical graphic model of information flow, partitioning a system into modules that show manageable levels of detail
  36. Prototyping
    building an experimental system rapidly and inexpensively for end users to evaluate
  37. Class and inheritance
    Object-oriented modeling is based on the concepts; objects belonging to a certain class or general categories of similar objects have the features of that class. Classes of objects in turn inherit all the structure and behaviors of a more general class
  38. Component-based development
    groups of objects have been assembled into software components for common functions, such as a graphical user interface or online ordering capability, and these can be combined to create large-scale business applications

    build small objects that do a routine task, and assemble small objects to create a new system
  39. Project management
    the application of knowledge, skills, tools, and techniques to achieve specific targets with specified budget and time constraints

  45. Stages in decision making
    • -Intelligence-discovering, identifying, and understanding the problems occurring in the organization
    • -Design-identifying and exploring various solutions to the problem

  46. MIS typically produce
    • primarily hard-copy reports
    • -fixed regularly scheduled reports based on data extracted from your TPS
  47. DSS
    (decisionsupport system ) provide analytical models or tools for analyzing large quantities of data and supportive interactive queries for middle managers who face semi structured decision situations.

  53. Neural networks
    used for solving complex, poorly understood problems for which large amounts of data have been collected
  54. Genetic algorithms
    used for finding the optimal solution for a problem by examining a very large number of alternative solutions for a prob: represents a solution as a string of 0s and 1s
