Categorical Databases by David I. Spivak.

From Slide 2 of 58:

There is a fundamental connection between databases and categories.

- Category theory can simplify how we think about and use databases.
- We can clearly see all the working parts and how they fit together.
- Powerful theorems can be brought to bear on classical DB problems.

The slides are “text heavy” but I think you will find that helpful rather than a hindrance in this case. ðŸ˜‰

From David Spivak’s homepage:

Purpose: I study information and communication, working towards a mathematical foundation for interoperability.

If you are looking for more motivation to get into category theory, this could be the place to start.

I first saw this in a tweet by Jim Duey.
