Answer 1

Database may have a fine grained access with lots of settings different for each user. It is not only scenario where you have one user for application access and that is all data security.

If we are talking about team development then probably there will be user group granted development access to database. Each user in this group will be member of your internal domain and have own passwords which database admin not supposed to manage and even know to allow access to database.

You don't have to put your database username and password in a file in your application somewhere

Any time you put a password in a plain text file, that's a security risk. Avoiding that is great.
