I'm curious about the 'lead' and 'lag' window functions mentioned in the discussion thread. How do they work and what do they represent?

Window functions like 'lead' and 'lag' are special functions that define a row frame with a specific length or offset. 'Lead' function allows you to access data from subsequent rows within the same result set, while 'lag' function allows you to access data from previous rows. These functions are useful for comparing values with other rows in a result set.
