NetSuite is one of the most user-friendly systems I’ve used in my 25-year career. I like that you can continually build and refine reports, add new checkboxes, and keep shaping the system so it becomes exactly what you want.
MySQL is fairly easy to setup and also to administer. Within 30-45 minutes of install one can have a read heavy reporting web application fully functional and operational. Some other minor refinements are also notable basic views and built in stored procedures are helpful for isolating application vs db logic. Swappable storage engines is also a benefit.
