From reading the Wiki page on B+Trees, it seems they are just a way to store data so that is is always sorted. If I ever needed to store data in such a way that it is always stored, I'd use a database+index. I don't know B+Trees because I've always reached for a database when I needed to do what B+Trees are good for. I've never had the need to learn B+Trees. I haven't had the need to learn many low level things. Not having a computer science background, there are tons of things I don't know, but those things just don't come up ever in my day to day programming life (other than interviews).
