Category Theory for the Sciences

I find Category Theory very difficult. This book looks like it's more accessible than the others I've tried.

I decided that I needed a formal category theory background when trying to understand typeclasses in Haskell. This book perfectly serves the aim, introducing the theory in a formal yet not too abstract way. The application to databases and ologs is nice. The book has a formal structure of a mathematical text (definitions, propositions, theorems, however often without a proof) and a lot of examples. Has a minor drawback though, namely a relatively high density of typos, but I guess it's a common first edition symptom.

This is a great and accessible book on applied category theory that is accessible to people who are not experienced mathematicians.

This book is useful for SIMULINK and MySQL modeling.

A very accessible and informative book on broad applications of category theory. Especially useful in information technology modelling
