DbRelationInfo

Represents metadata for a database relation in Datagrok.

DbRelationInfo describes how two tables are connected, including the schema/table pairs, participating columns, cardinality, and whether this relation is considered a primary navigation path.

Mutation methods do not modify underlying database, they just create metadata in Datagrok.
