2. Derived Tables in IDTDerived tables should be used in heavy universes as this will replace multiple tables by a single derived table, which is a lighter tables, thereby reducing the weight of Universe.

Creating Derived Table

Goto the Edit mode of your universe, then you can see the Master view.

Click on Insert and then click on Insert Derived Tables.





A panel will open to Edit the SQL expression for the derived table.SELECT all the columns from the table panel such as country_id, region_id and city_id for the derived table.

FROM clause holds the tables names whose columns are selected for the derived table.Now you can see the SQL Expression of the Derived table in the expression panel.





Click on Validate.

click on Close.

You can see the created derived table in the master view below.The created table has columns which we have selected from multiple tables.





Identifying the useless tables

Now Delete the undesired tables.





You can see that the 3 tables are deleted on which the derived table is created.

Creating New Joins

Create the joins with derived tables.

Detect the cardinalities of the joins.Double click on the join, click on DetectClick on Ok.









In the master view you can see the joins between the derived table and customer table and also between derived table and resort table.

Note:You should not add multiple derived tables because it will increase the complexity of SQL query and will badly effect the performance of the universe. The performance instead of increasing , will decreases.So you need to strike a balance , you must add one or two derived tables and not more than that.
