Question about AdventureWorksDW2008R2 sample database

    Domanda

  • Hi,

    I found that all of the facts tables in the AdventureWorksDW2008R2 include a RevisionNumber column which always includes “1”.

    What is the usage of RevisionNumber colums?

    Thank you,

  • Data in fact tables can change over time so one implementation for tracking changes is to implement a Revision/Version number.  The values are all 1 because no changes have been made to the data in the fact tables.
