data base is what it sounds like, a base for your data, you can refer to it as a container for all the stuff you want to store. it is actually not that hard to. learn simple db manipulation, but first you will have to specify the language you are using at least, or maybe you want to maintain SQL bases manually probably? what is the aim?
studying everything related to data helps you with ethical hacking tho. almost everything*. ifvyou know how to use DB and how to maintain everything in it, you are almost there! second thing is how everything is protected, this is the fun part! after you do everything with db and want to be the ethical hacker, hack your DB. then make a protrction in the program so no one can actually hack your DB like that. then try another thing! hacking things like that is cool cause you do not harm anyone :D
i think that sql is cool. or even c# and manipulate you sql from there! database is just a set of data. a bunch of rows and columns, values and keys. i will try to explain more later if time will let me bro. try to read about it, it is simple!
