What is a Database?

A database is somewhere you store information. There are some cool things about databases that matter to us at this level -- here they are:

  • Databases can hold a shit ton of data
    • that's the scientific term
  • Databases can hold data between sessions
    • If I log on to Facebook today and make a post, when I go back tomorrow, the post will still be there. Why? It's stored in a database.
  • Databases are efficient at navigating this "shit ton" of data
    • We won't get too far into why this is the case, but believe me, they're pretty good.
