First, you should count the number of rows in the tables and determine the type of data stored in each column. Second, you should analyze the existing data values and work with users to determine (1) multivalued dependencies, (2) functional dependencies, (3) candidate keys, (4) primary keys and (5) foreign keys. Finally, you should check the validity of the possible referential integrity constraints.
