18 Questions
What does Flow.BI do after selecting business keys for concepts based on data profiling?
Identify relationships between concepts
What is the result of creating links between concepts by Flow.BI?
Some (or even many) links might not be correct
What is planned for a future release regarding the generation of incorrect links by Flow.BI?
Stop generating them (black-listing)
Flow.BI selects business keys for concepts based on data profiling.
True
The decision to create links between concepts is based on an internal confidence value.
True
In a future release, Flow.BI plans to stop generating incorrect links by black-listing them.
True
Match the following actions with their descriptions:
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
Match the following outcomes with their descriptions:
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
Match the following concepts with their implications:
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
What is the impact of the false links in the Data Vault 2.0 model generated by Flow.BI?
They add inefficiencies but no data inconsistencies
What is the current recommendation regarding the use of the false links identified by Flow.BI?
Do not use these links for now
How do the false links impact the validity of the Data Vault 2.0 model?
The model remains valid, but it could be less efficient due to the false links
Flow.BI creates Data Vault links based on potential relationships between concepts, but there may be false links in realistic data models.
True
The presence of false links in the generated Data Vault 2.0 model can impact its efficiency, but not its data consistency.
True
Flow.BI recommends using the false links for now while they work on improving the algorithm.
False
Match the following terms with their descriptions:
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
Match the following statements with their implications:
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
Match the following actions with their impacts:
Creating Data Vault links based on potential relationships = May result in false links in realistic data models Selecting business keys for concepts based on data profiling = Part of the process in Flow.BI Black-listing incorrect links in a future release = A planned measure to prevent the generation of false links Using false links while working on improving the algorithm = Current recommendation by Flow.BI
