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.

Tracking database changes
If there are lots of changes in many places, you can see all of them from the Database Changes window. Important! This window is available only in DataGrip, but not in other IntelliJ-based IDE's.
