CloverDX Designer Overview

CloverDX Designer is a visual tool that lets you extract data from a source, transform it, and store it in a target. CloverDX Designer is an Eclipse-based Java application that runs on any platform where Java 1.6 or later is supported, including Windows, Macintosh OS X, and Linux.

Install CloverDX Designer

You can download a free trial version of CloverDX Designer by following these steps:

  1. On the CloverDX website, click Get a Trial.
  2. Follow the on-screen instructions to install CloverDX Designer.

Install the Vertica Client Driver

CloverDX ships the Vertica JDBC drivers for Vertica 7.0 and 7.1. Since Vertica drivers are forward compatible, you do not need to install a later version of the driver to use CloverDX with Vertica. However, if you are using a later version of Vertica and wish to enable more recent features, you must install the appropriate driver.

Note For details about client driver and server version compatibility, see the Vertica documentation.

To install the Vertica JDBC driver, follow these steps:

  1. Navigate to Vertica Client Drivers.
  2. Download the JDBC driver package.
  3. Follow the installation instructions in the Vertica documentation:
