This is a database question related to app development.

Hello, developers

When users register an evaluation on a restaurant, it is saved as a store registered in the app Other users can search for the store I'm going to make an app like a restaurant evaluation cafe, such as leaving comments. (If my explanation is not appropriate, it refers to applications such as Coupang and Wemakeprice, excluding financial transaction functions.)

I'm an individual developer, so I can't spend a lot of money

I was trying to figure out the database type to match the cost.

Since the app I want to create is RDBMS

We're looking at two types: Maria DB and Cubrid

Is it right to choose between these types?

If it is RDBMS, I understand that a complex search is possible,

I'm leaving a comment because I'm curious about the developers' opinions

I'm posting this because I can't read clear articles while looking for a lot of things to look for.

I would appreciate it if you could answer my question^{^}
