It's very easy to learn, it has many features that we can use in our project like class diagramming or entity relationship diagrams etc., also I really appreciate how well organized this program as one of its best feature! Well nothing so far i dislike about my experience with using giDE but maybe there are some issues related only for me because if you have any problems feel free contact their support team they will help us out quickly regarding your problem!! We used mostly Entity Relationship Diagrams (ERD) which helps others understand better what exactly happens when something happen between two entities connected by an association relation ship.
