Master window frame syntax with ROWS and RANGE specifications for precise calculations

Understand frame boundaries: PRECEDING, CURRENT ROW, FOLLOWING, and UNBOUNDED options

Control exactly which rows are included in window function calculations

Implement moving averages, running totals, and custom sliding window analytics

Distinguish between ROWS (physical) and RANGE (logical) frame types and when to use each

Avoid common frame specification mistakes that produce incorrect results
