How to create a database application?

Question

Mobile development

Concept: there is a database, people enter data there, it is public and others can find it through a search.
Also attach a rating to each news.
Tell me, please, the topics in which you need to rummage for the implementation of such a thing.
I mean something like a reference book, nothing complicated. Let's take sweets as an example, a person comes in and looks for information about some new snickers. And there he gets 3-4 "reviews", which were written by people who have already tried this same Snickers.
That's all, you don't need more functionality.
Thank you.

Let me translate for you:
What kind of car should I buy to carry goods.
And nothing more.
These conditions fit both a light pickup truck, and a sedan with a trailer, and a Gazelle, and a Kamaz, and a trucker's truck, and a truck and a van ....
