Tables that you drag to the logical layer of the Data Source page canvas must be related to each other. When you drag additional tables to the logical layer canvas, Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can ' t determine the matching fields, you will need to select them.

If no constraints are detected, a  Many-to-many  relationship is created and referential integrity is set to  Some records match . These default settings are a safe choice and provide the most a lot of flexibility for your data source.

Data blending simulates a traditional left join. The main difference between the two is when the aggregation is performed. A join combines the data and then aggregates. A blend aggregates and then combines the data.

Right click on any measure, and choose Discrete as shown:

Once you do this, the green pill becomes blue in colour, indicating that it is now Discrete!

Explanation

Relative date filters dynamically update to show a time period relative to when you open the view, such as the current week, the year to date, or the past 10 days. Relative date filters make it easy to create views that always show the most recent data.

Step 1 : Drag a date field to the filter shelf

Right-click (control-click on Mac) and drag a date field from the Data window to the Filters shelf. In the Filter Field dialog box, click Relative Date, and then click Next.

Step 2:  Select a time unit

In the Filter dialog box, click Relative dates, and then select the unit of time for the filter. For example, to show only the three most recent weeks, select Weeks.

Here, you can clearly see that the  default date is TODAY

Explanation

Yes, it is very much possible to use measures in the same view multiple times. For example, refer to the image below:

We are using  BOTH  the  Sum  of the revenue and the  AVG  of the revenue in the same view!

According to the  Tableau Desktop Specialist Exam Guide , city, country, and airport are three geographic roles that you can assign to a field. Address and time zone are not geographic roles in Tableau.

In Tableau, you can aggregate measures or dimensions, though it is more common to aggregate measures. Whenever you add a measure to your view, an aggregation is applied to that measure by default. The type of aggregation applied varies depending on the context of the view.

When you add a measure to the view, Tableau automatically aggregates its values. Sum, average, and median are common aggregations; for a complete list, see List of Predefined Aggregations in Tableau.

The current aggregation appears as part of the measure ' s name in the view. For example, Sales becomes SUM(Sales). Every measure has a default aggregation which is set by Tableau when you connect to a data source. You can view or change the default aggregation for a measure—see Set the Default Aggregation for a Measure.

You can change the aggregation for a measure in the view from its context menu:

To display the complete list of potential data connections when connecting to a server in Tableau, you should select " More " under the " To a Server " option. This action will provide a comprehensive list of server types and data sources that Tableau can connect to.

Upon clicking on a filter, we see the following options:

Clearly, Regex Match is not one of these options!
