Database Design Question | User types

Hi, still learning Bubble (and new to app development in general). I have a database design question for the app I’m developing in Bubble. Essentially my app is going to have two types of users (landlords and tenants). My question is, should I be creating two data types (i.e. two separate DB tables) for each type of user or should I have all types of users in one single data type and only separate them by a differentiating field, such as ‘role’ or something like that?

The same database and one field to identify the type of user.
