The visual representation of the data structure is great. I can easily see how my tables are related to each other. There's nothing that I dislike about this software. It works well with all databases. We've been using it for years now and have had no issues. It makes designing databases easy and fast. It also helps me keep track of changes as they happen. It's free so there's not much to dislike. I highly recommend this software if you're looking for an easy way to generate database diagrams. This software is very helpful when creating database designs. It allows me to quickly create a diagram and then fill out the details later.
