I like how easy it was to use this software as opposed from using other programs that are more complicated (for me).
It's not too much of an added work load if you have used any type in DBA systems before because they do most everything already set up! There really isn't anything bad about moon modelers at all; however there could be some things improved upon such but nothing majorly so far!! So many different types can easily switch between them without having issues with compatibility problems etc.. The only thing i dislike would probably just come down personal preference which may change depending what your needs/wants might look exactly when creating models within MMDs - maybe try out multiple ones until one suits better? This program helped us keep track very well throughout our projects by being able to create various kinds of relationships among tables we were working off including 1.
