If you're just vibe coding a tool for yourself, you don't have 'production database' at all even if you use database technology for storage. Just like many Android apps use local sqlite DBs but they're not production databases.
Of course in this case no traditional wisdom about production databases matters to you. In other words, it's off-topic.
I commented this elsewhere: There's thousands of small and medium business though. They have maybe one true CRM, and a dozen spreadsheets/files floating around that would benefit becoming proper apps. People delete spreadsheets all the time!
Sure don't give an LLM agent write access to the modeled CRM that took months/years to build.
But turning a spreadsheet into an app in a few days? By giving the LLM proper read/write capabilities for velocity? I think the case is there for it. Right tool for the right job.
