When you click on a database under your Account Dashboard you will be directed to the Database Dashboard.  This dashboard is specific to the database you selected.   Unless you go back to your Account Dashboard and select a different database, all the work you do will be to this database. 
The dashboard at a glance contains comprehensive widgets, and several lists that are specific to the database you selected. 
If you are unsure of the database you selected, look at the breadcrumbs at the top of the page. Next to the house will be the database name you selected. At any point you can click the house to be directed back to the Home Page/ Account Dashboard, or you can click the database name to be directed back to the database dashboard.
