Transformations

Transformations allow you to change the final output of a unified dataset in Tamr without having to transform each of the individual input datasets before loading them into Tamr. Examples of Tamr transformations include concatenating addresses or names that are stored by multiple input attributes together into a unified attribute, cleaning values by removing whitespace or delimiters, applying consistent formatting to dates, and so on.

Transformations modify the unified dataset of a project. Transformations do not alter input datasets directly.

For detailed information about Tamr transformations, see the Transformations Guide.

You can define transformations in schema mapping, mastering, and categorization projects. To work with transformations, choose the Unified Dataset tab.

Note: To add transformations to a mastering or categorization project you must indicate that you want the project to include this feature.

If you decide to include transformations in a mastering or categorization project after you have created it, locate the project on the Tamr dashboard and move your cursor over the top right corner to access Edit (pencil icon). The same dialog opens so that you can check Enable Transformations.

For more information, see the Enabling Transformations in Categorization and Mastering Projects.
