Modern astrophysics is using every day more big databases. One of the mostly used interface to databases is MySQl (or its recent free fork MariaDB). I present in this lecture a python library to deal with MySQL databases: PyMySQL. In the lecture the examples are using access to 3MdB (https://sites.google.com/site/mexicanmillionmodels/), which requires a password. You can ask for it to me, or adapt the example to connect to other databases.
