> indexedDb is an API. This API is more primitive and limited than SQL. This API is basically a key value store with indices and transactions. This is what many SQL databases are implemented on top of (Postgres for example). SQL isn't an API. It's a language. Something to query a SQL database in the browser would constitute the API (thus WebSQL). You are mixing up language and API here. That's your first mistake. > So yes it is absolutely possible to implement a SQL database on top of indexed DB, and that would be the architecturally logical thing to do. And it's trivial to implement indexedDB over Sqlite, in fact, that's what Firefox did. Where is the other way around? Where are RDBMS implemented on top of indexedDB? > The fact that Firefox goes the other way around is an implementation detail. No it isn't. It demonstrates my point entirely, that it is trivial to implement indexedDB on top of Sqlite, which makes Mozilla developers a bunch of hypocrites for not letting developers access an Sql layer directly.
