How to properly name tables, columns in a database?

Question

MySQL

Hello. I study databases, installed MySQL, created a database. Question - how to correctly name the database, tables, columns in the database? The PL has rules for naming variables, methods, etc., and the database has such rules and recommendations. Google gives you different options. Why I ask, a) so as not to get confused later, b) so that the computer does not swear, I don’t really want to rewrite everything later, it’s better to do it right right away. For example, how to properly name a column: "name column" or "name_column" or "NameColumn", etc. If there are no rules, then how do you comrades call these entities?
Thank you all for your constructive responses.
