We can rearrange the equation, and substitute current values for each of the above parameters to get a value for n; if a page is accessed more frequently than this, it is worth buying enough memory to store it Current disk technology and memory and disk prices give a value of n around 1/300 times per second (or equivalently, once in 5 minutes) for pages that are randomly accessed This reasoning is captured by the rule of thumb called the 5-minute rule: If a page is used more frequently than once in 5 minutes, it should be cached in memory In other words, it is worth buying enough memory to cache all pages that are accessed at least once in 5 minutes on an average For data that are accessed less frequently, buy enough disks to support the rate of I/O required for the data The formula for nding the break-even point depends on factors, such as the costs of disks and memory, that have changed by factors of 100 or 1000 over the past decade However, it is interesting to note that the ratios of the changes have been such that the break-even point has remained at roughly 5 minutes; the 5-minute rule has not changed to say, a 1-hour rule or a 1-second rule! For data that are sequentially accessed, signi cantly more pages can be read per second Assuming 1 MB of data is read at a time, we get the 1-minute rule, which says that sequentially accessed data should be cached in memory if they are used at least once in 1 minute The rules of thumb take only number of I/O operations into account, and do not consider factors such as response time Some applications need to keep even infrequently used data in memory, to support response times that are less than or comparable to disk access time Another aspect of tuning is in whether to use RAID 1 or RAID 5 The answer depends on how frequently the data are updated, since RAID 5 is much slower than RAID 1 on random writes: RAID 5 requires 2 reads and 2 writes to execute a single random write request If an application performs r random reads and w random writes per second to support a particular throughput, a RAID 5 implementation would require r + 4w I/O operations per second whereas a RAID 1 implementation would require r + w I/O operations per second We can then calculate the number of disks required to support the required I/O operations per second by dividing the result of the calculation by 100 I/O operations per second (for current generation disks) For many applications, r and w are large enough that the (r + w)/100 disks can easily hold two copies of all the data For such applications, if RAID 1 is used, the required number of disks is actually less than the required number of disks if RAID 5 is used! Thus RAID 5 is useful only when the data storage requirements are very large, but the I/O rates and data transfer requirements are small, that is, for very large and very cold data. birt gs1 128 Bar code EAN - 128 Font in BIRT Reports — OpenText - Forums

Within the constraints of the chosen normal form, it is possible to partition relations vertically For example, consider the account relation, with the schema account (account-number, branch-name, balance) for which account-number is a key Within the constraints of the normal forms (BCNF and third normal forms), we can partition the account relation into two relations: account-branch (account-number, branch-name) account-balance (account-number, balance) The two representations are logically equivalent, since account-number is a key, but they have different performance characteristics If most accesses to account information look at only the account-number and balance, then they can be run against the account-balance relation, and access is likely to be somewhat faster, since the branch-name attribute is not fetched For the same reason, more tuples of account-balance will t in the buffer than corresponding tuples of account, again leading to faster performance This effect would be particularly marked if the branch-name attribute were large Hence, a schema consisting of account-branch and account-balance would be preferable to a schema consisting of the account relation in this case On the other hand, if most accesses to account information require both balance and branch-name, using the account relation would be preferable, since the cost of the join of account-balance and account-branch would be avoided Also, the storage overhead would be lower, since there would be only one relation, and the attribute accountnumber would not be replicated Another trick to improve performance is to store a denormalized relation, such as a join of account and depositor, where the information about branch-names and balances is repeated for every account holder More effort has to be expended to make sure the relation is consistent whenever an update is carried out However, a query that fetches the names of the customers and the associated balances will be speeded up, since the join of account and depositor will have been precomputed If such a query is executed frequently, and has to be performed as ef ciently as possible, the denormalized relation could be bene cial Materialized views can provide the bene ts that denormalized relations provide, at the cost of some extra storage; we describe performance tuning of materialized views in Section 2126 A major advantage to materialized views over denormalized relations is that maintaining consistency of redundant data becomes the job of the database system, not the programmer Thus, materialized views are preferable, whenever they are supported by the database system Another approach to speed up the computation of the join without materializing it, is to cluster records that would match in the join on the same disk page We saw such clustered le organizations in Section 1172. birt ean 128 BIRT Barcode Plugin for eclipse BIRT versions 2.x, 3.x and 4.x ...
