How to allow Users to have multiple data in their own name


I am very new to bubble, so this might be very simple but…I am trying to build an app to which, once a user registers he can input different trips and keep record of the ones in the past and in the future. At the moment, I have one Data Type for the User (the default), on the Trip information Data, and one for Transportation Mode. To make sure I can relate the databases, I am doubling up some information that could be necessary, however I was wondering if there is a cleverer way to construct the structure.

Thanks in advance for your help.
