# Let's build a database!

As I may or may not have mentioned, I work with LucidDB in my day-job. It's pretty awesome, and I've learned a lot, though the underpinnings of the database architecture itself are still fairly mysterious to me. I would wager there are some low-hanging fruits in the C++-based Fennel core that could result in significant speedups of certain queries, but it's a complicated code base that it's confusing where to begin.
