Common Characters: Find and group values that have letters or numbers in common. This option uses the ngram fingerprint algorithm that indexes words by their unique characters after removing punctuation, duplicates, and whitespace. This algorithm works for any supported language. This option isn't available for data roles. For example, this algorithm would match names that are represented as 'John Smith' and 'Smith, John' because they both generate the key 'hijmnost'. Since this algorithm doesn't consider pronunciation, the value 'Tom Jhinois' would have the same key 'hijmnost' and would also be included in the group.

The box plot visualization displays the distribution of average profits by region. The distribution of profits is represented by the range of the box (interquartile range) and the whiskers (which often represent the total range excluding outliers). From the image provided, the South region has the smallest visible range within its box and the shortest whiskers, indicating the smallest distribution of average profits among the choices provided.

To ensure that the data is updated every hour, you need to select Extract Refreshes from the data source menu on Tableau Server. This will allow you to add a new extract refresh schedule or edit an existing one. You can specify the frequency and time of the refresh, as well as any custom options or credentials. New will create a new data source, Connected Workbooks will show you which workbooks use this data source, and Connections will show you which tables or files are connected to this data source.

To ensure that the data is updated every hour on Tableau Server, you would need to go to the 'Extract Refreshes' option. Here, you can schedule the data extracts to refresh at the desired frequency, which in this case would be every hour.

Using relationships: You can use relationships to link the secondary data source with the primary data source based on a common field. This will allow you to use fields from both data sources in your visualization without creating new fields or duplicating data. You can then replace references to update the dimension values. For example, you can use relationships to link the updated dorm codes with the primary data source and then replace Dorm_Code with Dorm_Code_New in your visualization.

To update existing visualizations with new codes without changing the field name, using relationships to bring in the secondary data source is appropriate. Then using Replace Reference allows you to update the references from the old dorm codes to the new ones while maintaining the existing field name.

To ensure that the extract also refreshes on the last day of the month at 18:00, you need to add a new extract refresh task to the workbook on Tableau Server. You can do this by selecting the workbook, selecting Refresh Extracts, and then choosing Schedule a Refresh. You can then select an existing schedule that matches your desired frequency and time, or create a new schedule with a custom frequency and time. This will add a new extract refresh task to the workbook, in addition to the existing one that refreshes every Monday at 10:00. You can also modify or delete the extract refresh tasks as needed.Reference:
