Since TYPO3 is a CMS that is completely based on databases, this chapter will discuss the structure of these databases. One of the most important topics is how the SQL queries are being handled. Some of these queries are used routinely during day-to-day work, while others are called upon strictly when developing extensions (we will cover more about this subject in the next chapter).
We recommend that you use phpMyAdmin to take a quick look at the structure of the database. Unfortunately, from TYPO3 version 4.0, it is no longer included, so you have to install it first. Also, your TYPO3 has to be configured so that installations of global extensions are permitted. You can find the appropriate settings in the installation tool under All Configuration. Enable the checkbox in the [allowGlobalInstall] array. Now you can install the phpMyAdmin extension. After installation, the phpMyAdmin menu item is available under Tools.
