In this chapter, we looked at Views from all sorts of module developer-oriented angles. We saw how we can expose our product entity type to Views. That was a breeze. But then, we also saw how our custom player and team data from Chapter 8, The Database API, can also be exposed to Views. Even if we did have to write some code for that, much of it was quite boilerplate as we were able to leverage the existing Views plugin ecosystem for almost everything we wanted.
