You can use external reporting tools to connect directly to a datamart only if you do not have a single-box installation using localhost:SERVICES.
You can now enable trusted users to establish connections by providing them with values of options REPORTS_DATABASE_HOST, REPORTS_DATABASE_PORT, REPORTS_DATABASE_READ_ONLY_USER, and REPORTS_DATABASE_READ_ONLY_PASSWORD.
