This article describes the table structure of the Marauroa database. You might want to have a look at [[Database Access]] which explains the high level API to access the database from your program code.
= Basic idea behind Database storage =
Arianne uses a database to store game state information so that the games can be truly persistent.
 
==Database Tables==
 
== Accounts ==
This are the tables of the Stendhal database schema:

{{Move everything below these lines into the [[Database Access]] article}}
Important tables which store original data, use the InnoDB engine. Tables with redundant data for easy access and logging use the MyISAM table type.
 
=== JDBC Database HOWTO===
{{TODO|Update to reflect DAOs}}
{{TODO|Add H2}}
Line 186 ⟶ 42:
The rest of code is handled by the server itself, and it will create the tables if they don't exist.
 
=== Storing objects in the database ===
Objects are stored in the database to save their state. This is an expensive operation, so it is only done every 10 minutes or on special events (like logout).
