I am creating a web site for a customer and they want to be able to create articles. My idea is to tag them so I am going to implement the system.

What is the best design, both from an architectural and a perfomance perspective:

1. To have table with all tags and then have a one to many relationship table that links a tag like this:

articles table with ID
tags table  with ID
one to many table with columns Article.ID and Tags.ID

2. To have one table with articles and one with tags for articles like this:

articles table with ID
tags table with Article.ID and tag text

Thanks in advance!
