Less Is More:  You’ve totally bought into the mantra that less complexity is by definition better.  Your product is relatively simple and fits nicely into the RoR framework including its data persistence layer.  You’re trying to intentionally avoid solving hard customer problems that might involve complicated database models  In fact, you may have even come up with your startup product idea based on one of the RoR tutorials or samples.  You’re convinced that the world does not yet have enough web-based, AJAX-driven, database-oriented CRUD applications for managing bugs, wine lists, CD/DVD collections or whatever.  In this case, your product was made for RoR.

Ruby on Rails is an open source framework that's optimized for programmer happiness and sustainable productivity. It lets you write beautiful code by favoring convention over configuration.
