Episode 97 - What Exactly IS A Database? Part II

We've approach the beast itself: SQL. Or, as it used to be known, SEQUEL. In this episode we will discuss how early navigational databases failed, and how we were able to move past them into a relational future. It's a fascinating tale about how careful research and planning can lead to much better tools.
