Suppose You Were In Charge Of The Database Operations Of A Company Whose Main Job Is To Process Transactions. Suppose The Company Is Growing Rapidly Each Year, And Has Outgrown Its Current Computer System. When You Are Choosing A New Parallel Computer, What Measure Is Most Relevant-speed Up, Batch Scale Up, Or Transaction Scale Up?why? |

Answer» With increasing SCALE of operations, we expect that the number of transactions submitted per unit time increases. On the other hand, we wouldn’t expect most of the individual transactions to grow LONGER, nor would we require that a given TRANSACTION should execute more quickly now than it did before. Hence transaction scale-up is the most RELEVANT measure in this SCENARIO. With increasing scale of operations, we expect that the number of transactions submitted per unit time increases.
