Now more popular database modeling tools Erwin, PowerDesign, Visio and so on. Visio out relatively late, with not a lot of people, but also a little weaker than the above function Erwin and PowerDesign. But ease of operation Visio is a big advantage.
I always use the database before PowerDesign, I feel very convenient. I liked him best thing is that you can select several fields for editing, set the field type, default value, etc. at the same time. But the only drawback is can not comment (comment) imported into the sqlserver database and other databases can be imported annotation, such as access. This, I feel very uncomfortable.
Erwin4.0 not support the comments imported into the database, but now Erwin4.1.4 can annotate imported into the database, so I had to reluctantly part to give up PowerDesign9.5 (PowerDesign10 not know whether to support), and the choice Erwin4.1.4 because the annotation database is very important for database designs.
