Urmas,
If you read her question carefully, which I reproduce here for your benefit: "Can anyone please tell me where can i find the mappings between the attribute names and Database columns?", you'll come to know that, her question will translate to:
1. "I can see some Attribute in the UI"
2. "I want to know their Columns in the DB"
So, its either that we understand her question correctly and you don't; or that she has not phrased her question properly. The only way to know that would be for her to clarify
If our answers is not what she is looking out for, we would be more than happy to help her with what she is looking out for, if she rephrases
