The following links will hopefully help to decrease the learning curve associated with learning SQL. While these sites have no affiliation to our project, and there are no guarantees, we have found them to be very helpful in gaining an understanding of the general commands and concepts upon which you can build your SQL knowledge.
Again, these sites have no affiliation with Babase, Duke University, or Princeton University (to my knowledge) and cannot be held responsible if the websites do something terrible to you or your computer.
