Server side of the Community and implemenation of the various Web Service methods. See the Webapp portion though on the deployment and setup of the community. Currently the Community classes use Castor (a JDO type library) allowing the connection to most any kind of database, but currently all tests have been using HSQLDB as the database of choice for the community. In the Webapp section is the explanation of the configuration of the community web service that describes about configuration files in case you wish to change over databases or make other small changes to the mappings.
