  • Patent number: 11442934
    Abstract: A method, a system, and a computer program product for executing a query.

Each calculation node corresponds to an operation being performed on one or more database tables stored at a database. The calculation nodes include one or more nodes specifying a window function operation. The window function operation including one or more first attributes and one or more second attributes.
