MS Access database on a smart phone

This is just a general question. I will try to investigate the details myself once I'm pointed in the right direction.  Is it possible to load an MS Access database on a smart phone? I'm using a Palm Treo 750WX (I think that's the model name) with a Windows Mobile operating system. I've seen some cheap software on the net that say they facilitate the use of databases on smart phones. One I came across was DB Anywhere. Another is Smart Database Viewer. Does anyone know about these products or any other ones that are good? Do I need them at all or can I load the Access database directly on the smart phone? Ideally I'd like to use my Access database just like I do on my regular PC. That is, I select which query to run from a listox, I enter query criteria in a textbox, and I press a button to run my query.
