### 3.2.2. Database Management

The default configuration of Nova Orchestra uses the Database persistence service and the HSQL Database. Nova Orchestra has also been tested with Oracle, MySQL and Postgres database system. To change to mysql, postgres or Oracle, you need to put the corresponding JDBC driver in the directory `$CATALINA_BASE/common/lib` and modify the `hibernate.properties` file (see Section 4.3.4.1, “Database Access Configuration”)
