NAME

UR::DataSource::RDBMS::UniqueConstraintColumn - Metadata about a data source's unique constraints

DESCRIPTION

This class represents instances of unique constraints in a data source. They are maintained by 'ur update classes' and stored in the namespace's MetaDB.

Multi-column unique constraints are represented by instances having the same table_name and constraint_name, but different column_names.
