General Unix Finally something really interesting to talk about. If you've used UNIX or any of its derivatives, you've probably wondered why there's /bin, /sbin, /usr/bin, /usr/sbin in the file system. You may even have a rationalisation for the existence of each and every one of these directories. The thing is, though - all these rationalisations were thought up after these directories were created. As it turns out, the real reasoning is pretty damn straightforward.

Databases are slow.

They are not.

And a filesystem is a database

It's not. Files are unstructured binary blobs. There is no way to query what's inside them.

optimized for data access in large units, many GBs in size.

So can databases handle TBs of data, not only GBs.

Databases are optimized for data access in tiny units, such as strings, or single numbers. They aren't good at huge units in hundreds of Mbytes.

They are.
