Rules for Mapping SQL Relational Databases to OWL Ontologies
... A column ssn in a table Employee in Fig. 5 is not a foreign key. Therefore, this column is mapped to a data type property ssn that uses a class Employee as its domain. This property has a maximum cardinality of 1, because the column ssn may have at most one value for each row in the table Employee ( ...
