Need expert advice on what to use to store this information

Hi. I’m working on a project, basicly multiplayer rpg cant call it mmo. Anyways. I noticed runescape private servers has a system, when you create an account, it makes a PLAYERNAME.txt file in a folder, storing data from player name and password(encrypted) to position (x,y,z).

Now. I would LOVE something as simple as this to store what players have in their inventory and all their data like username and such. Is it possible to have unity create a .txt file in my websites database upon registration ingame with all data I tell it to precreate, and use it as a working saving system and account system?

Can this be done in unity, and if so is it a good way? Any examples perhaps? Thanks!

You’ll need to learn the SQL framework that is included with the MSDN language. In MySQL you can create SQL functions(or I believe they are called functions) that you can trigger and pass information to. These functions can create all of the table entries that you need to create the new account, and set default values.
