You're missing the point. A database or a normal http API is great if you're accessing the data from outside a blockchain. If you want smart contracts to access the data, it's better if the data is available natively inside the blockchain. You're probably not interested in smart contract, but there are other people that are trying to build smart contracts which use that data. One simple example would be a prediction market.
