Should I have more than 1 database connection?

I have started to make a webapp with mvc2. I am using the built in users database that is available by default. I want to add tags and more stuff that will need to be stored in the database.

At the moment under data connections, I have ASPNETDB.mdf which has it's tables and all its other information.

If I want to make a tags table, do I create a new data connection or should I add it to that database?


You could have multiple databases but it would make it difficult to perform queries. A single database could have many tables and it is the recommended approach.

Put your tags table in the same database.

Databases can handle hundreds of tables. Each table can be associated to other tables via key relationships.

Here's a good place to learn about designing databases:
