If you are interested in creating your own databases, this may be one of the most important tutorial. Why? Because, at their heart, the most useful and efficient databases use well-structured tables to store their information.
This tutorial explains just about everything you will ever need to know about tables and fields: how to link two or more related tables, how to create indexes for faster performance, and how to create a primary key field, which uniquely identifies each record in a table. This tutorial also explains how to change all the properties and settings for your tables' fields, such as how they are formatted and what kind of information they can store.
