We are thinking of building a dapp for finding salon near me and allowing booking. In such application end users has to be shown the salons which are at a certain distance from their current location. Where would be query that data from. Cause I don't think so that kind of querying is possible in solidity. Do we need to bring in any RDBMS in such a scenario to store salon data so that we can query it easily and booking information can be sent to blockchain.
Is hybrid application the only way out? People are talking about IPFS should be used for storing the images, videos and other data. Is that the solution, if yes then how would we query it from there? Moreover, would it be fast enough?
You likely want to separate your application into two parts:
- The part which shows the available booking times
- The part which makes a new booking
