Also, use MODEL_PERCENTILE to return the probability of the expected value being less than or equal to the observed mark, based on other predictors. Use the new MODEL_QUANTILE table calc to return a target value at a specified percentile, based on other predictors. 2 New Table Calcs for Predictive modeling Newly created tables are now more accessible since they are available in the Tableau Server, Tableau Online search, and when connecting to data in both Tableau Desktop and web authoring. Admins can also monitor where the data is being written since it is also available via the Metadata APO and Postgress database. Write to database is integrated with Tableau Catalog, so database tables are included in the lineage and impact analysis, so admins can track where the data is going. The external databases available are: SQL Server, Oracle, PostgreSQL, MySQL, Teradata, Snowflake, and Amazon Redshift, with more databases planned for future releases.Īnd if you use Tableau Prep Conductor to schedule flows to run regularly, you can ensure your data is always up to date. Now your data will be loaded to a temporary database table first to then move to the destination table after the data is completely loaded.Īpart from that, you will be able to write to external databases from Tableau Prep, incrementally loading data directly to database tables, appending only newly added rows to your destination table.

It allows you to quickly visualize, clean, merge, and prepare your data for analysis.Įven though Prep has been a long-praised feature, it lacked the ability to export to external databases, meaning you could only export your data in CSV format.
