Using the visual no-code Datamap builder you can quickly and easily build a dataset. Each Datamap is a data product with:

  • A dataset

  • SQL (auto-generated for you)

  • Metadata

  • Operations reporting

You will learn how to:

  1. Find the best fit data with Data Explorer (Promethium's intelligent data catalog)

  2. Transform data without writing code

  3. Auto generate a SQL query

  4. Query the dataset in real time

  5. See the options available for publishing the Datamap

Table - A new table is created in your chosen data source

dbt Model - dbt Core™ is used to write the data to your chosen data source (Go to guide)

18. Click on Done. Once the model is successfully published, you should be able to see it at the top part (depending on how you sorted the list) of the list in Data Explorer page.

To get a live preview, click on the model name then go to Samples tab.
