Great job in making it through the course.

In this last section, we're going to talk about some advanced sequel topics. We're going to talk about the concept of sequel and database indices. An index is something that can allow your program to be able to run faster queries but there are times to use them and times not to use them and we're going to discuss how those should work.

We're also going to get into some more advanced topics around database structuring. We're going to talk about database normalization which is the process of being able to make sure that our databases are built and designed as efficiently as possible. Then we're going to finish off with talking about modeling and diagramming our databases so that we can visually see how the data in the tables are all mapped together.
