Need some type of database app

Hi All.
I REALLY need some advice. Nearly all of my websites use the 1 or more of the WPMUDEV plugins and i need something and am not sure if you do it.
i'm trying to build a wpress site that is going to need a form of database plugin. it would need to be used for the best example i can show you is on this website http://www.algarvepackage.com/ i need something that can hold many hotels and that i can control and edit in the back end but also display like the website i listed.
is there a plugin like this available??
Any suggestions would be REALLY appreciated
