- Unique_key abstract "In database relational modeling and implementation, a unique key is a set of zero, one, or more attributes. The value(s) of these attributes are required to be unique for each tuple (row) in a relation. The value, or combination of values, of unique key attributes for any tuple should not be repeated for any other tuple in that relation.When more than one column is combined to form a unique key, their combined value is used to access each row and maintain uniqueness. These keys are referred to as aggregate. or compound keys. Values are not combined, they are compared using their data types.When a column or set of columns is defined as unique to the database management system, the system verifies that each set of value(s) is unique before assigning the constraint. After the column(s) are defined as unique, an error will occur if an insertion is attempted with values that already exist. Some systems do not allow key values to be updated, and all systems will not allow duplicates. This ensures that uniqueness is maintained in both the primary table and any relations that are later bound to it.".
