A database query optimizes relation joins using dynamic programming; what happens to memory use as the number of joined tables increases?

A)Decreases due to early optimization
B)Increases due to storing intermediate results
C)Remains constant regardless of relations
D)Fluctuates randomly, no predictable trend

💡 Explanation

Memory usage increases because dynamic programming stores intermediate results of subproblems to avoid recomputation; therefore, as the number of tables and joins increases, more intermediate tables are stored, increasing memory consumption, rather than remaining constant or decreasing.
