Dimension Tables vs Lookup Tables - the real difference?

  • I'm reading about dimension and lookup tables and trying to get a better understanding between the difference. So far the best descriptor i have to separate these two tables is below. I would like to see if perhaps i'm missing something or if i'm understanding this correctly?

    "For each dimension used in a project, a lookup table is required to provide meaningful information. For example, a "product" dimension might be based on a lookup table that includes the productID, productName, productType, productManufacturer, and so on. Dimensions define a hierarchy for the information retrieved by the lookup table, so that it can be organized and presented in a meaningful way."

    Example:

    Dimension table

    VW -> Golf -> Features

    VW -> Jetta -> Features

    Honda -> Accord -> Features

    Lookup table

    Features

    1 -> xxx

    2 -> yyy

    3 -> zzz

    manufacturer

    vw ->aaa

    honda ->bbb

    car

    golf ->ccc

    jetta ->ddd

    accord ->eee

    etc

  • Aha 🙂
