This is basic ALSX Report, built using a object oriented design. This a very basic design and layout for simplicity, but this style can also be used with Rails or a straight database connection using gems like pg, mysql, etc. to generate dynamic reports. It shows it inherits from a master Report class where you can share pieces and parts among multiple reports.
