1. I came across this relatively good Data Base site in which someone has attempted to ensure most of the important things are traced to an area if not the street address.For eg when u enter a mobile number in the search query,u will get to know the city and the state from which the number belongs to or like pincodes of India are traceable to exact area identification or even vehicle numbers are traceable to the city....nice attempt but still looking for more in depth query geneartion...i m sure they are working on it...meanwhile enjoy what they offer now.Few links are given below :
