Activiti needs the support of the database at runtime, and uses 25 tables to read the content of the process definition node into the database table for subsequent use.

The databases and versions supported by activiti are as follows:

database type	Version	JDBC connection example	illustrate
h2	1.3.168	jdbc:h2:tcp://localhost/activiti	Database configured by default
mysql	5.1.21	jdbc:mysql://localhost:3306/activiti?autoReconnect=true	Use mysql-connector-java to drive the test
oracle	11.2.0.1.0	jdbc:oracle:thin:@localhost:1521:xe
postgres	8.1	jdbc:postgresql://localhost:5432/activiti
db2	DB2 10.1 using db2jcc4	jdbc:db2://localhost:50000/activiti
