This study presents the results from a comparison study performed in order to evaluate Ruby onRails modeling and code generation features against J2EE environment and AndroMDA. For thatpurpose quality scenarios were built in order to to perform metrics measurements that in the latterstage were used to evaluate the both platforms. The scenarios’ main purposes were to measuredevelopment speed, implementation complexity, modeling time, and versioning.Through this process, it was possible to identify key features that pointed Ruby on Rails as thefaster development environment. The results showed that a Rails developer could write less code(for implementing the same functionalities) than a J2EE developer. The time spent for modeling thedatabase schema in textual environment was less than then AndroMDA visual environment. Thetime needed for creating a diagram of the database schema using Ruby on Rails reverseengineering plugins was less compared to J2EE. Finally, Ruby on Rails database versionmanagement allows the developer to switch between different database schemes in less and simplersteps than in J2EE or AndroMDA.
