# Teradata OLAP Connector

This article describes how to establish a Teradata OLAP connection.

## Before you begin

Before you begin, gather this connection information:

- Connection name
- User name and password

Use this connector with Tableau Desktop on a Windows computer.

When you connect to Teradata OLAP data, you select from a list of connections, each representing a system data source name (DSN). A connection appears in the drop-down list if a system DSN exists for that connection. You can use the Windows ODBC Data Source Administrator utility to create a system DSN, or contact your database administrator.

### Driver required

This connector requires a driver to talk to the database. If the driver is not installed on your computer, Tableau displays a message in the connection dialog box with a link to the [Driver Download](https://www.tableau.com/support/drivers) page where you can find driver links and installation instructions.

## Make the connection and set up the data source

1. Start Tableau and under Connect, select Teradata OLAP Connector. For a complete list of data connections, select More under To a Server. Then do the following:
    
    1. Select a connection from the drop-down list.
    2. Enter your user name and password to log on to the server.
        
        If Tableau can't make the connection, verify that your credentials are correct. If you still can't connect, your computer is having trouble locating the server. Contact your network administrator or database administrator for more assistance.
    3. Select Sign In.
2. On the data source page, do the following:
    
    1. (Optional) Select the default data source name at the top of the page, and then enter a unique data source name for use in Tableau. For example, use a data source naming convention that helps other users of the data source figure out which data source to connect to.
    2. Search for or select a catalog.
    3. Search for or select a cube from the catalog.
    4. Select the sheet tab to start your analysis.

## Work with Teradata OLAP data

Named sets from a Teradata OLAP data source are displayed in the Sets area of the Data pane in Tableau. You can interact with these named sets in the same way you interact with other custom sets in Tableau. For more information, see [Create Sets](https://help.tableau.com/current/pro/desktop/en-us/sortgroup_sets_create.htm). You can view underlying data for Teradata OLAP data sources, provided the database administrator has enabled this functionality. For more information, see [View Underlying Data](https://help.tableau.com/current/pro/desktop/en-us/inspectdata_viewdata.htm).
