    Unanswered: Identifying Functional Dependencies

    If i have a table with the headings

    Organisation Country of Origin Software Name Software type Version

    What would the functional dependencies be? The primary key is a composite key with organisation and software name

    what have you tried
    what dependencies have you identified (so far)
    what makes you believe that these are correct (or incorrect)
    I'd rather be riding on the Tiger 800 or the Norton

    Depending on the data definitions for the columns, any of them could be functionally dependant on one or both of the key attributes. Note that based on the attribute names alone, none of these attributes are sufficient to constitute a key. Without the data dictionary or at least formal attribute definitions, I can't help you solve this problem.

    In theory, theory and practice are identical. In practice, theory and practice are unrelated.
