We at JetBrains know how important it is to track what has been changed in your project from one version or revision to another. This is why PhpStorm 2.1 brings you new Diff Tools for comparing DB objects (Data Sources, Schemes, Tables) and folders. In later updates we’re planning on including even remote to local files comparison as well. Diff Tools are available via Ctrl+D/Cmd-D hotkey, or from context menu, wherever you may need them.
Say, to compare two Data Sources (or Tables, or Schemes, come to that), all you need to do is select them in Data Sources tool window, and then invoke the Compare action either from context menu, or via the toolbar:
Comparing two local folders is just as easy: the action is available in Project View file tree.

Note: since WebStorm doesn’t support working with Databases there are no such features in WebStorm.
