    How to design table to be normalized with many foreign key columns?

    I am designing a table in Teradata with about 30 columns. These columns are going to need to store several time-interval-style values such as Daily, Monthly, Weekly, etc. It is bad design to store the actual string values in the table since this would be an attrocious repeat of data. Instead, what I want to do is create a primitive lookup table. This table would hold Daily, Monthly, Weekly and would use Teradata's identity column to derive the primary key. This primary key would then be stored in the table I am creating as foreign keys.

    This would work fine for my application since all I need to know is the primitive key value as I populate my web form's dropdown lists. However, other applications we use will need to either run reports or receive this data through feeds. Therefore, a view will need to be created that joins this table out to the primitives table so that it can actually return Daily, Monthly, and Weekly.

    My concern is performance. I've never created a table with such a large amount of foreign key fields and am fairly new to Teradata. Before I go on the long road of figuring this all out the hard way, I'd like any advice I can get on the best way to achieve my goal.
