Zoomdata Version

Connecting to Teradata

The Teradata connector allows you to visualize data stored in Teradata databases. Zoomdata supports Teradata versions 13.1 through 15.1

PREREQUISITES

Before you can establish a connection from Zoomdata to Teradata, a Teradata connector server needs to be installed, configured and enabled first by the Zoomdata Account Administrator.

Starting with version 2.3, Zoomdata's architecture has been enhanced to enable the deployment of new connectors as standalone components running in their own process space. To learn more and access the setup instructions, refer to the article Configuring a New Connector Manually .

The table below lists information on the features that are supported by Teradata:

Supports Distinct Count? Yes
Supports Live Mode/ Playback? Yes
SparkIt Capable? Yes
Supports Group-by Time? Yes
Supports Multi Group-by Charts? Yes
Supports Histogram? Yes
Supports Box Plot? Yes
Custom SQL Capable? Yes
Supports Last Value? Yes
Supports Partition? No

Starting with Zoomdata v2.5.3, the Teradata connector will require a JDBC driver to be configured before you can connect to your data source. You can download the driver from the vendor's site. If you are upgrading, keep in mind you will need to configure the JDBC driver (refer to the article Upgrading Zoomdata Server to v2.5 for instructions). For more information, refer to the Add a JDBC Driver article.

CONFIGURING THE CONNECTION

For details about what is provided in each page of the connection process, review the article Source Connection Workflow . Depending on your needs, you can either follow the steps in order from start to finish or jump to a specific section in the connection process:

Start

To configure the connection, perform the following steps:

  1. Log into Zoomdata.
  2. Click the Sources menu item.

    Figure 1
  3. Click the Teradata connector icon.

General Page

  1. Specify the name of your source and add a description (if desired).

Connection Page

This page defines the connection source for Zoomdata to be able to access the data source. If this is the first time setting up a connection, then you need to input the necessary credentials. If a validated connection already exists, you are given the option to use it.

  1. To create a new connection, select the Input New Credentials option.
  2. Enter a unique name for the connection (to help distinguish between other connections in this Zoomdata account).
  3. Specify the JDBC URL.
    If authentication has been set up, provide the username and password.
  4. Click Validate .
    If successfully validated, the connection is saved.

Tables Page

The Tables page lets you select the schema and table to connect with and provides a preview of the selected table. In addition, caching options and toggling the availability of the fields can be done on this page.

  1. Select the schema, if available, and then select the desired table to connect to Zoomdata.

  1. Create a Custom SQL query, if needed.
Zoomdata wraps your SQL query into a SELECT statement. If specific statements inside the wrapped query are not supported by your data source, the query will not be executed.
  1. Toggle the caching options (SparkIt and Caching), as needed.
Spark It capability is planned for deprecation in a future release.
  1. Toggle the availability of the fields, as needed.
  2. Click Next to continue.

Fields Page

The Fields page lets you (1) configure attribute options, (2) create custom labels for the fields in your data source (that will be displayed in the charts), (3) manage the Volume metric, and (4) work with Calculations.

  1. Determine whether the field should be visible or not to the user.
  2. Create unique label names, as needed, for each Label field.
  3. For the Type column, you have the option to edit the field type (although usually you won't need to do this).
  4. For the Configure column, numeric and time-based fields may be edited:
    • Numeric types including Money, Number and Integer - ability to select a default aggregation function
    • Time fields - ability to define the default time pattern and granularity; if the time field provides granularities of hour, minute and second, then a time zone label may be applied
  5. Select fields for Distinct Counts as needed.
  6. Refresh the connection to a particular field, as desired.
  7. Configure Filter Display settings for fields.
  8. Edit the Volume Metric settings, as needed.
  9. Work with Calculations , if available and as needed.
    If you are setting up a new connection, the Calculations section will not be available until after the connection is saved.
  10. Click Next to continue.

Refresh Page

The Refresh page lets you schedule asynchronous jobs to update the source metadata. For guidance to set up a refresh schedule, refer to the article Using the Zoomdata Scheduler .

Charts Page

On the Charts page, you can:

  1. Edit Global Default Settings .
  2. Select the Standard and, if available, Custom chart styles to be used with the data source.
  3. Set default parameters (group, sub-group, colors, sorting, and so on) for each chart style.
