Show HN: A Database Generator for EVM with CRUD and On-Chain Indexing

Hey all, We are working on a database generator that takes in your data schema in YAML format and uses it to generate a database in Solidity with CRUD and on-chain indexing capabilities. You can deploy the generated contracts to any EVM blockchain. We have a demo and playground if you want to test it out. It's in the early stages, we have planned some exciting features, and we'd appreciate your feedback!
