attributes and name column property

I'd like to verify my logic on using the name column.

In my dimension i have a two tables

The main table contains the majority of the fields that will create the attributes for the

dimension some of these fields are code values where the description is contained

in a second table.

So here is my question/logic

Instead of adding the Description field as an attribute from the second table,

I should take the code value from the main table as the attribute and then set the

"name Column" property to reference the description from the second table.

The way you describe is definitely better than defining 2 attributes. Having more attributes is less efficient. You will need to define more aggregations to get a better performance.
