Designing and Implementing a Data Science Solution on Azure

The Introduction to MariaDB course covers the basics of the SQL language as implemented by MariaDB. The course is designed to give delegates practical experience in writing SQL statements using the mysql client command line program and GUI tools. The basic SQL statements, including the use of SQL functions and the basic table and view handling statements are introduced.

Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.

The delegate will learn and acquire skills as follows:

• Using client programs to access a MariaDB database
• Creating, altering and dropping a MariaDB database
• Writing SQL statements to select data from a MariaDB database
• Writing joins and subqueries
• Using SQL expressions
• Using SQL aggregate functions and scalar functions
• Inserting, updating, deleting and replacing rows
• Creating and altering tables, indexes and views
• Using transactions
• Granting and revoking access privileges on tables and views
• Exporting and importing data

Anyone who needs to access and work with a MariaDB Database or is migrating from MySQL to MariaDB.

To provide the skills needed to create and alter a MariaDB database and query and modify data held within such a database.

There are no formal pre-requisites for the Introduction to MariaDB course, although an understanding of databases and exposure to information technology in general would be useful. This knowledge can be gained by attendance on the Relational Databases & Data Modelling Overview course.
