No it doesn't. Why would relationships matter? You handle the relationships in SQL queries, and just copy query results to structs.

Congratulations, you've invented an ORM.
Majority of ORMs really are nothing more than this.
But then it's nice to have something that generates optimised, database-specific SQL, can handle date/number conversion, supports many-many relationships, converting BLOB to binary streams etc.
That’s 1% of an ORM.

It's at least 30% of most ORMs. And if your homebrew ORM actually gets wide use, it'll grow from there.
Source: Wrote an ORM that other people actually use. Still adding features, twelve years later.
This is clearly not what anyone means when they say they don't want an ORM.
An ORM library maps an entire relational database to a graph of objects, with the intention of abstracting away the relational database. Copying query results to structs doesn't actually do any of that.

The minute you add relationships your approach becomes unusable.
There is a reason ORMs have persisted for over 30 years.
