If you’re not sure what git (or Revision Control) is, here are some resources: Wikipedia on Revision Control (excerpt) “Revision control (also known as version control (system) (VCS), source control or (source) [...]

Validations in Ruby on Rails are essentially nothing more than methods that ensure that the data in a model is valid before saving it to the database. Traditionally, we validate data coming in using conditional expressions (for example, if email != NULL or if passwd==passwd_confirmation).
