Mobile DataBase

Hello.

i have an web app that manage car reservations, for that i have an entity reservation that includes the car ID and other entities apart that complete the car, like Model, Brand etc ...


Now i have to "transfer" database web for mobile but for optimizing i know that i can just create a local entity like "Car" that can have model name and brand name instead of create again those entities.

Next the local entity that we create is to show on a list.

My question is , which steps should i follow do to that? Is my 1st time in mobile , sorry for that.
