-- Convention for database items with version control:
--
--   CREATE TABLE items ( -- dbentry_type=x
--     id        SERIAL PRIMARY KEY,
--     locked    boolean NOT NULL DEFAULT FALSE,
--     hidden    boolean NOT NULL DEFAULT FALSE,
--     -- item-specific columns here
--   );
--   CREATE TABLE items_hist ( -- History of the 'items' table
--     chid integer NOT NULL,  -- references changes.id
--     -- item-specific columns here
--   );
--
-- The '-- dbentry_type=x' comment is required, and is used by
-- util/sqleditfunc.pl to generate the correct editing functions.  The history
-- of the 'locked' and 'hidden' flags is recorded in the changes table.  It's
-- possible for 'items' to have more item-specific columns than 'items_hist'.
-- Some columns are caches or otherwise autogenerated, and do not need to be
-- versioned.
--
-- item-related tables work roughly the same:
--
--   CREATE TABLE items_field (
--     id integer,  -- references items.id
--     -- field-specific columns here
--   );
--   CREATE TABLE items_field_hist ( -- History of the 'items_field' table
--     chid integer, -- references changes.id
--     -- field-specific columns here
--   );
--
-- The changes and *_hist tables contain all the data. In a sense, the other
-- tables related to the item are just a cache/view into the latest versions.
-- All modifications to the item tables has to go through the edit_* functions
-- in editfunc.sql, these are also responsible for keeping things synchronized.
--
-- Columns marked with a '[pub]' comment on the same line are included in the
-- public database dump. Be aware that not all properties of the to-be-dumped
-- data is annotated in this file. Which tables and which rows are exported is
-- defined in util/dbdump.pl.
--
-- Note: Every CREATE TABLE clause and each column should be on a separate
-- line. This file is parsed by lib/VNDB/Schema.pm and it doesn't implement a
-- full SQL query parser.
