Can ClickHouse be considered a relational database management system?

ClickHouse is a columnar analytical database optimized for processing large volumes of data and analytical queries. It is not a traditional relational database management system because:

• ClickHouse lacks some traditional relational features, such as full transactions and complex table relationships.
• The main focus is on fast aggregation and analytics, not on supporting complex relational models.

Therefore, ClickHouse can be considered an analytical DBMS with relational elements, but not a full-fledged relational database management system.
