First, you need to understand the Database's reason for everyday. For example, why do we use it? Why's database important? Where and how can I use it?

After all it, you can begin to learn how to create tables and insert datas. I suggest you study it in SoloLearn and try each new thing that you learn.

If you haven't a database's software, try in KhanAcademy's website. There are a SQL's interpreter and a course.

Actually, I code there (at least, untill SoloLearn applies a SQL playground 😂😂).
