36. Table has no anomalies.






37. A field data type that automatically stores a unique number for each record as it is added to a table.






38. A field - set up in a query - that displays the result of an evaluated expression rather than displaying stored data.The value of the calculated field is re-calculated each time a value in the expression changes.






39. A relation that contains no multivalued attributes.
