How does this skill handle table joins?

It uses Entities; by defining the same entity name as a 'primary' or 'foreign' type across different views, the system automatically maps relationships and generates joins.

How do I verify that my semantic layer is correct?

The skill provides access to 'oxy validate' to check YAML syntax and 'oxy build' to verify references across views and topics.

What is an Oxy semantic layer?

It is a metadata layer that sits between your database and business users, translating complex SQL schemas into understandable business terms for natural language querying.

What are synonyms used for in the view files?

Synonyms allow the natural language engine to map various user phrases (like 'turnover' or 'sales') to a single technical field (like 'total_revenue').

Can I use custom SQL expressions in views?

Yes, both dimensions and measures support the 'expr' field, allowing you to use standard SQL functions, CASE statements, and complex calculations.
