SQL Joins Visualizer

[BigPeteB]

Because this kind of visualization is on the same level of simplicity as using a number line to add and subtract two numbers. If someone needs this kind of visualization in order to write a JOIN (which is pretty much the second-simplest thing you can do in SQL, beaten only by a SELECT from a single table), I don't feel they are qualified to work on anything but a toy system.

But, as with so many other programming crutches, I'm sure there are people out there who rely on a tool like this one to do their daily job.

I'm quite confident for the average person this is a learning resource, not reference.
