Tableau 2020.3 Write to external databases in Tableau Prep

Write to external databases in Tableau Prep

The new version of Tableau 2020.3 offers users the ability to update and prepare external databases directly in Tableau Prep. The data preparation process is simplified by storing the data in a centralized way and preparing it directly in Tableau. Starting from now, users can use the drag and drop method to map the fields with the corresponding data from the data set.

It’s easy. First, connect to the data set, either files (Microsoft Excel) or data bases (amazon Red shift, IBM DB 2, Microsoft SQL, Vertica, Oracle, SAP Han and many others) and bring tables or sheets to the data pane. You can combine data from multiple data source types. New data sets can be added to the data preparation flow at any stage. You can also use the Data Interpret or that works the same as in Tableau Desktop.

data scaffolding in Tableau Prep

Before performing unions or joins, it is likely that you need some cleaning operations on your data: removing fields, changing data types, creating calculated field, splitting columns, remove numbers, letters or punctuation, trim spaces, make uppercase or lowercase, group values.

Once the data is clean, you can pivot, aggregate, join, union data. Tableau Prep will show you the immediate results of any action you perform on the data.
