Overview

This section provides detailed procedures on the different types of data transformations you could perform.

You can transform your data using the pre-built transformation steps, or by through certain functions in the data preview panel. Transformation widgets for data science models are also available in Yellowfin's Marketplace, that allows users to integrate data models, such as PMML, PFA, R and H2O, into their platforms and apply them on their data.

 

The Data Transformation module offers different ways of performing transformations on your data. These include transformation steps that can be dragged into a flow, performing inline field transformations, and even data conversion. Besides the transformation steps that come included with this module, you can also download and install plug-ins to include more steps in your environment.

Here is a breakdown of the different ways of performing transformations:

  • Built-in transformations: This refers to transformations in the transformation step panel that come included in the data transformation module. These do not require any type of set up.
  • Downloadable transformation step: You can also download and install special plug-ins from the Marketplace that become available in the transformation step panel. (See the Transform Steps section in the Marketplace for all available options.)
  • Inline field transformations: This refers to functions that users can perform directly on the data (in the data preview panel or the step configuration panel).

 

Following is a list of all the transformations that you can perform on your data. Click on a transformation name to learn how to use it in your flow.
