Dose anyone know any good tuts that can teach/help me learn how to create database’s for gamemode’s and addons.

What you would need to know to create a database is SQL. Google SQL Tutorial or MySQL Tutorial.
Here’s an example of how a database could look like:

CREATE TABLE `points` (
    `steamid` VARCHAR(32) NOT NULL,
    `playername` VARCHAR(255),
    `points` INT(11),
    `lastvisit` VARCHAR(255)

etc, etc, this is just a rough example.

What you’d also want to read up on would be the gmsv_mysqloo module for GLua.

Hope this helps you a bit!
