-- Gnucomo database creation script.

-- This SQL script creates the initial tables for the Gnucomo database.
-- Before running this script with 'psql -f', you should have your
-- DBA create the database and give access permissions.
--
--  $Log: create.sql,v $
--  Revision 1.14  2003-07-09 07:14:59  arjen
--  New database tables: notification_check, notification_check_buffer,
--  notification_check_line and object_statistics.
--
--  Revision 1.13  2003/03/29 08:27:05  arjen
--  New columns in the table 'log_adv_daemon_email': size, pri, relay,
--  status_details and dsn.
--  Added several indices for the table 'log_adv_daemon_email'.
--
--  Revision 1.12  2003/02/21 08:38:38  arjen
--  Added new table to the database: log_adv_daemon_email.
--
--  Revision 1.11  2003/02/16 08:24:38  arjen
--  Added a new entry to the action table: Notification was displayed in the listing
--
--  Revision 1.10  2003/02/14 06:32:27  arjen
--  Setup the groups and database permissions. The three groups
--  are: view, ops and admin.
--  Added a new entry to the action table.
--
--  Revision 1.9  2003/02/13 08:46:54  arjen
--  Added log, notification and parameter counters to the 'object' table.
--  Counting these things at the time a user interface needs them is
--  too slow. Other programs, like gcm_daemon en gcm_input should prepare
--  these counters for quick retrieval.
--
--  Revision 1.8  2003/02/08 07:36:41  arjen
--  Added new table to the database : log_adv_daemon
--
--  Revision 1.7  2003/02/05 09:29:08  arjen
--  Bug fix: action.statuscode was in upper case.
--
--  Revision 1.6  2003/01/20 07:29:48  arjen
--  Added new tables to the database: parameter_class and parameter_notification
--
--  Revision 1.5  2003/01/18 08:46:48  arjen
--  Added new records to the 'type_of_issue' table.
--  Changed semantics of actionid 9 in the 'action' table.

1       Entry in the system     new     This indicates that a notification has been entered into the system.
2       Display to user opn     The notification has been displayed to the user. It doesn't mean that the user actually read the notification, but he/she should be aware. For that reason we consider the notification to be OPEN
3       Remarks added   pen     Remarks have been added to the notification.
4       Priority changed manually       pen     The priority of the notification has been changed by the user.
5       Priority changed automatically  pen     The priority of the notification has been changed by the system. This can be the result of an action by the user or an automatical escalation.
6       Action taken    pen     An action has been taken.
7       Assignment to user      pen     The notification has been assigned to an user.
8       More information or research needed.    inv     The notification is relevant and will be handled, however more information or research will be needed. For that reason the status has been altered to UNDER INVESTIGATION.
9       Investigation completed pen     Investigation has been done. Information is available to fix the problem.
10      Job output no longer valid      cls     By making a newer job output a valid reference, this data has been obsoleted. Since it was a reference once the output isn't interesting anymore and thus the notification can be closed.
11      Action taken - please verify    cls     An action has been taken and things should have been resolved. Before the notification can be closed a verification has to be done. The new status is now VERIFY.
12      Action not verified     pen     A check has been done and the results were not good. New verification is needed. The status has been changed back to PEN.
13      Action verified cls     A check has been done and the results were approved. The notification has been closed.
15      SMS sent        opn     An SMS has been sent.
14      E-mail sent     opn     An e-mail has been sent.
16      Fax sent        opn     An fax has been sent.
17      Log entries shown       \N      The log entries relevant to the notification have been shown.
18      Notification closed     cls     The notification has been closed.
19      Notification reopend    opn     The notification has been reopend.
20      Redisplayed to user     \N      The notification has been presented to a user. This is not the first time
21      Displayed in list       \N      The notification has been presented in a list with other notifications.
