• Step 1. Log in to Plesk with your account credentials.

• Step 2. Navigate to the "Websites & Domains" page.

• Step 3. Select "Databases" from within your website overview.

• Step 4. Scroll down to the database you want to assign to a website.

• Step 5. Click the drop down box and select the website the database should be assigned to.

Assigning a database to a website doesn't affect the website functionality itself but it helps to structure things within the control panel and can be handy especially if you have a lot of websites and databases.
