   DDL
      Data Definition Language. DDL is a type of database-specific
      syntax used to define the structuring of schemas. Common DDL
      statements include ``create``, ``drop``, and ``alter``.

   link
      Link items define a specific relationship between two object types. Link
      instances relate one object to one or more different objects.

      More on links in :ref:`Data Model <ref_datamodel_links>`.

   set reference
      An identifier that represents a set of values. It can be the name of an
      object type or an *expression alias* (defined in a statement :ref:`with
      block <ref_eql_statements_with>` or in the schema via an :ref:`alias
      declaration <ref_eql_sdl_aliases>`. or a qualified schema name).

   simple path
      A path which begins with a :term:`set reference`.
