  Database conditions allow alternate paths of control depending on the
  truth value of a test involving conditions peculiar to the database
  environment.  The database conditions are the tenancy, member, and
  database key conditions.

  The tenancy conditions determine whether a record in the database is
  an owner, or member, or a tenant in one or more sets.

  Format -

                        { OWNER  }
   [ NOT ] [ set-name ] { MEMBER }
                        { TENANT }

  set-name is a subschema set name.
