Good database table design for storing localized versions of data [closed]

Answer 1

Let's say you have a products table that looks like this:

Products
----------
id
price

Products_Translations
----------------------
product_id
locale
name
description

Then you just join on product_id = product.id and where locale='en-US'

of course this has an impact on performance, since you now need a join to get the name and description, but it allows any number of locales later on.
