一个工作流设计及定义的系统,可以直接与数据库结合进行系统工作流程的定义及应用.

-- postgresql db schema

--
--        A way of using this :
-- 
-- $ su - postgres
-- postgres$ createuser owfe
-- Shall the new user be allowed to create databases? (y/n) n
-- Shall the new user be allowed to create more new users? (y/n) n
-- CREATE USER
-- postgres$ createdb owfe
-- postgres$ psql owfe
-- owfe=# alter user owfe encrypted password 'owfe';
-- ALTER USER
-- owfe=# \i postgresql.sql
-- ...
-- CREATE TABLE
-- psql:/home/jmettraux/poya/releases/openwfe-engine-worklist-and-webclient/sql/postgresql.sql:55: NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index 'xattribute_pkey' for table 'xattribute'
-- CREATE TABLE
-- owfe=# grant insert,delete,update,select on owfehistory to owfe;
-- GRANT
-- owfe=# \q
--
-- replace 'owfe' with the name of the user that will run the openwfe 
-- binaries

-- postgresql can handle larger keys than mysql :-)
