The tutorial provides a quick start guide on integrating business intelligence tool Tableau with Couchbase 4.0, leveraging N1QL and ODBC/JDBC drivers via SIMBA. To begin, the required software must be installed, including Tableau Desktop, SIMBA ODBC for Couchbase Driver, and Couchbase 4.0 with the "travel-sample" bucket. The SIMBA ODBC driver is configured to connect to a node on the Couchbase cluster running the Couchbase Query Service, and an ODBC data source name (DSN) is set up to access the Couchbase server. N1QL queries require indexes to exist on the documents being queried, so a primary index is created on all documents in the travel-sample bucket using the cbq.exe utility. Once configured, Tableau can be connected to the Couchbase cluster, and reports can be built using JSON documents stored in Couchbase, enabling semi-structured data access for business intelligence users.
