Overview of this book

This book will take you through all the nitty-gritty parts of MariaDB, right from the creation of your database all the way to using MariaDB’s advanced features. At the very beginning, we show you the basics, that is, how to install MariaDB. Then, we walk you through the databases and tables of MariaDB, and introduce SQL in MariaDB. You will learn about all the features that have been added in MariaDB but are absent in MySQL. Moving on, you’ll learn to import and export data, views, virtual columns, and dynamic columns in MariaDB. Then, you’ll get to grips with full-text searches and queries in MariaDb. You’ll also be familiarized with the CONNECT storage engine. At the end of the book, you’ll be introduced to the community of MariaDB.

Summary

In this chapter, we discussed two techniques to take database backups and restore them.

First we discussed how to generate a CSV file using SELECT ... INTO OUTFILE, and restore it with LOAD DATA INFILE. The flexibility provided by the SELECT statement can be a great advantage.

We also discussed the mysqldump tool that can be used to take a dump of our database. Then, we can run these files like any other file containing SQL statements.

In the final part, we learned some small tricks that can be used to speed up the loading of a backup.

In the next chapter, we will learn how to use views and virtual columns to have some data logic in your database instead of your application.
