+Graph references are values used to specify which graph is targeted in a query.
+They are principally used with the xref:clauses/use.adoc[`USE`] clause, xref:functions/graph.adoc[graph functions], such as `graph.byName()` and when referring to databases and aliases in administration commands.
+
+The output of the name column in `SHOW DATABASES` and `SHOW ALIASES FOR DATABASE` can be used as an identifier when referring to a specific graph references.
+
+When referring to a constituent in a composite database, the identifier is defined as <composite-name>.<alias-name>, where the dot functions as a separator between the composite database name and the alias name. While we do not recommend creating databases or aliases containing dots, it is possible to refer to the alias `some.alias` in the composite `some.composite` as `some.composite.some.alias`.
