No Such Thing as Unstructured Data? Define it With Care.

Right,  the term is broadly used.  It really means in many cases 'not structured enough for the purpose at hand'.  In a recent architecture project fo BI it meant 'not in a corporately managed database'.  In other cases it means 'free text data'.  And in other examples image data.   Or  'not in an established database field'.  It is a good idea to understand what it means in your example.  TDWI makes some related points.
