    Capella Analytics extends the grammar, statements, and capabilities of SQL++ for Analytics used with the Analytics Service in Couchbase Server and Capella. This guide is a reference to the full syntax and semantics of the SQL++ query language that you use with Capella Analytics services.

    SQL++ for Capella Analytics is a Couchbase implementation, focused on parallel data analysis, of a SQL-for-JSON query language specification called SQL++.

    SQL++ for Capella Analytics is similar to SQL. The differences between the languages are due to the differences in the data models that each language is designed to serve. SQL interacts with the flat, schematic world of relational databases, while SQL++ for Capella Analytics interacts with the nested, schema-less or schema-optional world of NoSQL systems like Capella Analytics. SQL++ for Capella Analytics is designed to work with the JSON data model.

    Grammar-guided explanations, diagrams, and examples of the SQL++ for Capella Analytics language follow.
