You can find data types for an attribute in the following ways:

  • View datatype metadata for a particular attribute
  • View the Structural Summary for an attribute, which includes datatype distribution and count metadata
  • View all attribute values and corresponding data rows for a datatype

There are two kinds of datatypes calculated automatically when you import data:

  • Inferred. Datatype derived from the full volume of data in the attribute.
  • Target. A reference of how the datatypes in the target (or current) attribute should look based on your actual data.

  3. Double-click an attribute.

    The Entity Member Attribute List View opens.

  4. Locate the metadata Decimals, Integers, or Strings.

    The count of distinct values that correspond to each datatype is displayed in the Value column.

  5. Locate the metadata Dec Dist %, Integer Dist %, and String Dist %.

    The percentage of the attribute that contains that datatype is displayed in the Value column.
