This article describes how Marauroa accesses the database internally and how you can add support for your own tables. The table structure of the Marauroa database is explained in [[Marauroa Database Structure]]. You might want to have a look at [[High Level Database Access]] |
This article describes how Marauroa accesses the database internally and how you can add support for your own tables. The table structure of the Marauroa database is explained in [[Marauroa Database Structure]]. You might want to have a look at [[High Level Database Access]] first. It explains the high level API to access the database from your program code. |

JDBC technology is an API that lets you access virtually any tabular data source from the Java programming language. It provides cross-DBMS connectivity to a wide range of relational databases. Unfortunatally it does not hide vendor specific stuff. Marauroa and Stendhal currently only work with MySQL because of that. Adding support for other database software would be very easy as the database specific code is concentrated in the classes JDBCDatabase (Marauroa) and StendhalPlayerDatabase (Stendhal). We have no need for that, so it was not done, yet. We will, however, accept patches for multi database system support, so if you need it, go ahead. |

The rest of code is handled by the server itself, and it will create the tables if they don't exist. |
