How can I query the feature title from database? 2010 has a table called Feature Tracking... but the 2007 content databases don't have any table called FeatureTracking.

Do you really need to read it from the database? As a best practice it's best to ignore that the database(s) even exist, you're much better off going through the APIs. If you use the server object object model you should be able to get references to the relevant SPWeb, SPSite or SPWebApplication and from that get the SPFeatureCollection that will give you all you want.

Additionally, querying the database outside of the API will invalidate any support agreements you have with Microsoft. Steve's suggestion is the best and most appropriate one to follow.Steven Andrews | SharePoint Professional | http://www.twitter.com/backpackerd00d | https://baron72.wordpress.com/

Come on now ... just a READ from the db never invalidated any support agreements. Yes, for a practical reason. I really need to READ the db. Just a Read.
