SQL is 43 years old – Here’s why we still use it today
SQL has the great side effect of creating structures that future employees can understand.  Its  a set of tables with relationships.  Given these you can quickly inspect the structures <i>independent</i> of the programming language dejour.  With a few commands a new employee can understand: business logic, hr, billing, reporting, and other major backbone principals in a matter of hours.  On the other hand, I have been at companies that jumped on the noSQL &#x2F; ORM &#x2F; wrap it until you can&#x27;t wrap it &#x2F; hide sql (rails).  When new employees show up... well... its a bunch of semi&#x2F;no structured stuff spread across thousands of lines of specific logic.
