ROW_NUMBER(): Assigns a unique sequential integer to rows within a partition.
RANK(): Assigns a rank to each row within a partition of a result set, with gaps for ties.
DENSE_RANK(): Similar to RANK() but without gaps in ranking values.
WHERE: Filters rows from a Table.
HAVING: Filters groups after aggregation, typically used with GROUP BY.
QUALIFY: Filters rows after window functions are applied (specific to some databases like Snowflake).
