Querying Object-Oriented Databases

Summary: XSQL blends SQL-like syntax with OO path expressions, selectors, and flatten/collapse operators. Key aspects: data+schema queries with OIDs, a viewing mechanism to form objects, and F-logic-inspired typing, yielding richer expressiveness than SQL. (summarized by gpt-5-nano on Feb 09 2026)
