Databases should contain their own Metadata – Use SQL Everywhere

Not clear if the author realises that all commercial SQL database engines support querying of the database's metadata using SQL. Or maybe I have misunderstood - I only skimmed the article.

Isn't his like it is in many relational databases, you can query them about the tables in them?

i think the key difference is making that metadata first-class and queryable across the whole system (lineage, stats, access patterns), not just information_schema / catalog tables. most rdbms expose schema metadata, but not things like which queries produced which rows, freshness, or cost/latency signals unless you bolt it on with tracing. curious if floe is treating metadata as data (versioned, joinable) or as observability sidecars?
