security of mssql database?

Hello, another question from a newbie to mssql.

Is there a way of allowing access to database only by providing username and
password (disabling trusted connection and preventing administrator to
access database through enterprise manager or otherwise without supplying
username and password)?

What I would like is that my application upon instalation creates database
with appropriate tables (already done this) and somehow solely creates and
manages user list and passwords so that there is no access to database other
through application. (Application would create a backdoor account should
something go wrong)

You can't deny a SYSADMIN from accessing your database. You just have to
ensure that only the right people have the SYSADMIN role.

To secure your database through your application, read about Application
Roles in Books Online. Make sure all access to data is through stored
procedures so that you don't have to grant permissions directly on tables.
