So, I was wondering if there is really some new features coming from JetBrains DataGrip software.
So far, I didn't find anything that is not already there in IntelliJ IDEA (Ultimate). I didn't spend much time using it though.
I am Max, the PMM of DataGrip.
We usually say that DataGrip provides the same functionality as all the other IDE's from JetBrains with the database support. As mentioned above, DataGrip provides better user experience as a standalone IDE.
OBSOLETTE:
Indeed, DataBase changes is the toolwindow which is available only in DataGrip. It lets you look at changes you are going to apply to source codes of various objects like views, procs etc. It is a minor difference, that's why we say "the same" to keep things simple.
