Which factor affects the actual physical implementation of rate of change classification?

  • The classification of source attributes
  • Availability of table compression in target database (correct)
  • Satellites in the logical model
  • The definition of the rate of change classes

    • What is one of the requirements for rate of change classification?

  • Satellites in the logical model
  • Usage-based query billing

    Match the following aspects of rate of change classification with their descriptions:

    <p>Definition of rate of change classes = Specifies the intervals at which data changes are measured Classification of source attributes = Determines the rate of change for different data sources Satellites in the logical model = Divided based on their rate of change Actual physical implementation = Depends on factors such as storage type and query billing</p> Signup and view all the answers

    Match the following factors with their influence on the actual physical implementation of rate of change classification:

    <p>Availability of table compression in target database = Affects the storage efficiency and performance Row-based storage vs. columnar storage vs. hybrid approaches = Determines the data storage and retrieval methods Usage based query billing = Impacts the cost of executing queries Satellites in the logical model = Divided based on their rate of change</p> Signup and view all the answers

    Match the following components with their role in rate of change classification:

    <p>Rate of change classes = Defines the intervals at which data changes are measured Source attributes = Classified based on their rate of change Satellites = Divided in the logical model based on their rate of change Actual physical implementation = Depends on the availability of table compression, storage type, and query billing</p> Signup and view all the answers
