There's some confusion of concepts here, I'll give a brief clarification.
In the 70s we got structured databases (meaning the structure of the data is defined, it's not arbitrary) and there were a lot of competing vendors, which resulted in some standards. SQL is a standard language that allows you to write queries that a database server executes (and gives you the results back). Access is one such database product (compatible with SQL), but it's meant for personal use by individuals and runs on your desktop.
There is a whole space of more serious database products like Mysql, postgresql, Microsoft SQL server and most prominently Oracle which are extremely widely used by companies everywhere. This forum stores its data in Mysql and the forum software uses SQL to get it in and out of the database.
But SQL databases, for technical reasons, are basically limited to a single machine. If you have the amount of data that Google has then it doesn't fit on one machine and hence was born NoSQL, a complete separate line of database products where the data is stored on multiple machines.

I guess I'll have to learn it, then.
