Which database to use to build an analytics app with PHP: what should have I to search for to find an answer : <p>I know the question I'm posting is a bit broad, but unfortunately I have no idea of what to search for.</p>

<p>So, my real question is: what should have I to search for to understand how to store and read data that need to be processed to get reports about something?</p>

<p>I'm referring to applications like Google Adwords, SemRush, Facebook Analytics and, in general, any kind of application that collect a very big amount of data and then use it to build reports.</p>

<p>Currently I use MySQL but I've read many times that it isn't the best solution to choose when approaching such kind of tasks.</p>

<p><strong>So, which should be my starting point to understand which alternatives I have and, after, to choose one?</strong></p>
