This article demonstrates how to create new data joins in the dataset Flight Delays, based on data previously imported into Arcadia from the datafile flights-2014-01.csv. The additional datafiles are airline-id.csv, airport-codes.csv, cancellation-code.csv, and airport-lat-lo ng.csv.
The following steps demonstrate how to make new joins.
On the main navigation bar, click Data.
The Data view appears, open on the Datasets tab.
Find the dataset in the list of datasets, either by scrolling or by using search, and click on it.
Dataset side navigation appears, open at Dataset Detail view.
In the side navigation menu, click Data Model.
Data Model view appears, and shows the name of the only table in the dataset. You may click Show Data to display the data of that table.
Click Edit Table Links to edit the data model.
Click the sign on the table representation.
Add Dimension Table modal window appears.
In the Add Dimension Table modal window, make the following selections:

.
This value is pre-populated to match the dataset's existing table, but it may be changed.
Edit Column Connections modal window appears.
