How useful are fuzzy lookup and fuzzy grouping ?

  • Is it really useful in real world jobs ? Can we do things efficiently without it ?

  • These components are usually used in Data Quality projects.

    For example, the Fuzzy Lookup can be used to match "Belgium" with "België", something the regular Lookup component can't.

  • Thanks. Koen. I am new so I don't know why the lookup function cannot make that distinction ?

    Also, are there any other examples in which a task can be done only with fuzzy and not regular lookup ?

    The lookup function is like a equi join in TSQL, it can only do exact matches.

    The fuzzy lookup uses fuzzy logic to do the matching, but it uses considerably more resources.
