Firebird has:
Computed columns with COMPUTED BY (since Interbase 6 or earlier, see
Interbase 6 language reference page 74), and with GENERATED ALWAYS AS:
www.firebirdsql.org/file/documentation/reference_manuals/reference_material/html/langrefupd25-ddl-table.html#langrefupd25-ct-gen-always-as

Arrays (see Interbase 6 Data Definition Guide page 76)

Triggers on VIEWS (see Interbase 6.0 Language Reference on Create
Trigger, specifically page 81 and 82). A lot of the time the
documentation seems to refer to tables when it also means views.
