I am trying to normalize a database I am building. One part of it

  • 0

I am trying to normalize a database I am building. One part of it is that I have many different tests that each can have many different tags. How would you deal with this?

Would you have a table with your tags and then have a limit on the number of tags per test?

I am new to databases let alone the whole idea of normalizing so forgive me if this is a very simplistic question.

    Usually, this’d be dealt with using two tables. A tags table, with each record consisting of a tag_id and tag_name (and potentially other metadata you want to include). Tags would then be associated with their tests via another table, test_tags, in which test_id and tag_id would be stored.

    If you want to limit the number of tags per test, you can easily run a SELECT COUNT(tag_id) FROM test_tags WHERE test_id=# query to figure out how many they’ve already added to it.
