Questions and Answers

What does Flow.BI do after selecting business keys for concepts based on data profiling?

  • Create blacklisted links
  • Remove all links for data inconsistency
  • Use incorrect links for data analysis
  • Identify relationships between concepts (correct)

What is the result of creating links between concepts by Flow.BI?

  • Links are removed for downstream analysis
  • Some (or even many) links might not be correct (correct)
  • All links are accurate and consistent
  • No links are generated due to data inconsistency

What is planned for a future release regarding the generation of incorrect links by Flow.BI?

  • Use incorrect links for upstream analysis
  • Stop generating them (black-listing) (correct)
  • Increase the confidence value for all links
  • Create more links to compensate for the incorrect ones

Flow.BI selects business keys for concepts based on data profiling.

Match the following actions with their descriptions:

<p>Selecting business keys for concepts based on data profiling = First step in the process Identifying relationships between concepts = Next step after selecting business keys Creating links between concepts by Flow.BI = Based on an internal confidence value Black-listing incorrect links in a future release = Planned action to address data inconsistency</p> Signup and view all the answers

Match the following outcomes with their descriptions:

<p>Some (or even many) links might not be correct = Result of creating links by Flow.BI No need to use incorrect links (up- or downstream) = Response to data inconsistency Confusing links in the worst case = Impact of using incorrect links Stopping the generation of incorrect links in a future release = Planned response to address confusing links</p> Signup and view all the answers

Match the following concepts with their implications:

<p>Data inconsistency = May result from using incorrect links Internal confidence value = Basis for creating links between concepts Up- or downstream usage of links = Decision on whether to use incorrect links Future release black-listing = Planned action to prevent incorrect link generation</p> Signup and view all the answers

Flow.BI creates Data Vault links based on potential relationships between concepts, but there may be false links in realistic data models.

The presence of false links in the generated Data Vault 2.0 model can impact its efficiency, but not its data consistency.

<p>True (A)</p> Signup and view all the answers

Flow.BI recommends using the false links for now while they work on improving the algorithm.

Match the following terms with their descriptions:

<p>Data Vault 2.0 model = Generated by Flow.BI based on potential relationships between concepts False links = Identified by Flow.BI in realistic data models Efficiency = Impacted by the presence of false links in the Data Vault 2.0 model Data inconsistencies = Not caused by the false links in the Data Vault 2.0 model</p> Signup and view all the answers

Match the following statements with their implications:

<p>Flow.BI identifies potential relationships between concepts = Leads to the creation of Data Vault links Generated Data Vault 2.0 model should be valid = May have inefficiencies due to false links Improving the algorithm = Will address the issue of false links in the model Recommendation to use false links for now = Temporary measure while algorithm is being improved</p> Signup and view all the answers
