What I like most about Oracle Data Modeler is the visual way it helps me understand database structures. I can see tables, relationships, primary keys, and foreign keys in one place, which is especially useful when working with an existing database. The reverse-engineering feature is also helpful because I can bring an existing schema into the model instead of creating everything manually. Overall, it makes database design and documentation much easier to manage. Review collected by and hosted on G2.com.
The main thing I dislike is that the interface feels a little outdated compared with newer database tools. It can also take some time to get comfortable with all the different options and features. When working with a large database, the diagrams can become crowded, so organizing the model properly takes some extra effort. Review collected by and hosted on G2.com.
