Sinossi

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computer science, the five-minute rule is a rule of thumb for deciding whether a data item should be kept in memory, or stored on disk and read back into memory when required. It was first formulated by Jim Gray and G. F. Putzolu in 1987, and then subsequently revised in 1997 and 2007 to reflect changes in the relative cost and performance of memory and persistent storage. The rule is as follows: The 5-minute random rule: cache randomly accessed disk pages that are re-used every 5 minutes.
