Hey.. good enthusiasm, but first before thinking of a database job get comfortable with the concept. There is alot to learn but dont get overwhelmed, baby steps. Im a junior developer working in backend with Oracle databases (Relational & Object-Relational)

After you feel comfortable on the basics try moving ahead learning more. You could do this with books or online resources. I personally like e-books and pdf files. I read them all the time, for a book recommendation check this
