Hello,___Thanks for sharing your requirement. Sorry, I could not find attachments, as mentioned in the description. Would appreciate, if you share it with us.____ As per my "understanding", you need an application, where users can enter information of state, city, street, plot which will gets stored in the database. You are willing to cover whole world, so this application will be a global application. So, you prefer to have map into this website, so that these locations entered by users will be plotted on maps. You would prefer something similar to Wikipedia, Google maps, etc. We have some "queries" for you: 1) How are you planning to check correctness / legacy of information shared, as any user can add the information? 2) As in coming years, main issue would be to manage these databases, as it will be heavy. Do you have any plans to manage this? _____ We would prefer to discuss with you in detail, so that, we can evaulate and suggest you best possible solution. Let me know your availability.
