Connection to an OLAP server.

OlapConnection is a subclass of {@link Connection}. It can be pooled by a connection pooling framework or obtained directly via the Java standard {@link DriverManager}. The JDBC URL prefix of olap connections is dependent of the driver implementation. Such implementations are, among others possible:

Olap4j's XML/A driver
Mondrian

Olap connections have a different metadata hierarchy than regular JDBC. The connection's metadata is available using {@link OlapConnection#getMetaData()}, and returns a specialized subclass of {@link DatabaseMetaData}. The objects at the root of the hierarchy are {@link Database} class objects.

A connection needs be bound to a database, a catalog and a schema. Implementations are expected to automatically discover these if no driver specific parameters indicated which ones to use. @author jhyde @version $Id: OlapConnection.java 407 2011-03-20 00:44:11Z lucboudreau $ @since Aug 22, 2006
