Appendix E. Installing MySQL and creating a database

In this appendix, I will show you how to create a MySQL database. In some of the examples we implement in chapters 12 through 14, we use an external database management system (DBMS). For these examples, you’ll need to create a database for your app to use prior to implementing the project.

For the database technology, you have plenty of options to choose from, like MySQL, Postgres, Oracle, MS SQL server, and so on. I encourage you to select the technology you like if you already have a preferred one. For the examples in the book, I had to choose a certain database technology, and I decided to use MySQL, which is free, lite, and easy to install on any operating system. You’ll find MySQL used ...
