Attrition: this tells us how many devices in the array can be lost without breaking the functionality of the array and losing data.
在DB 2中,类型阵列的变量类似于任何其他SQL数据类型的变量。

因为它仅限于单个机器,所以想要让它有效率,你需要强大的数据库服务器和存储阵列网络。
Since it is limited to a single machine you need a powerful database server and a storage array network for it to be effective.
分段大小指的是在移到该阵列里的下一驱动器之前写入一个驱动器的数据总量。
Striping size refers to the amount of data written to one drive before moving to the next drive within the array.
但更重要的是,阵列是在应用程序和存储过程之间或在存储过程之间流动的数据集合的非常方便的表示形式。
But more importantly, arrays are a very convenient representation for collections of data that flow between an application and stored procedures or between stored procedures.
PODS在文件服务器上存储医疗记录图像文件;它使用IBMDB 2数据库存储相应的元数据,用网络附属存储阵列存储图像文件,包括PDF和文本。
PODS stores medical record image files on file servers; it USES an IBM DB2 database to store corresponding metadata and a network attached storage array for the image files, including PDFs and text.
对于这些测试,模拟的邮件用户数据库均匀地分散在14个阵列上。
For the tests, the simulated mail user databases are spread evenly over the 14 arrays.
假设位于一个存储区域网络(SAN)存储阵列上的数据库在每次对它运行某个查询时具有糟糕的性能。
Suppose a database that resides on a storage area network (SAN) storage array exhibits poor performance every time a certain query is run against it.
而诀窍就是找到一个弹性阵列,能够将非单调的数据集“变成单调数据集”,或者换言之,就是降维。
The trick is to find an arrangement of springs that "flattens" the data set, or in other words, reduces its dimensionality.
每个RAID阵列的数据驱动器数目的确定可能相当复杂,因为一个阵列中的驱动器数目并不一定等于进行数据填充的驱动器数目。
Deciding on the number of data drives for each RAID array can be rather complex, since the number of drives in an array is not necessarily equal to the number of drives in which data is populated.
为衡量阵列的性能影响,使用900gb的数据库且执行oltp(联机事务处理)工作负荷。
To measure the performance impact of arrays, a 900gb database was used and an OLTP (Online Transactional Processing) workload was exercised.
像其他编程语言中的阵列一样,在SQLPL中对算法编码,DB 2阵列可用作辅助数据结构。
Like arrays in other programming languages, DB2 arrays can be used as an auxiliary data structure when coding algorithms in SQL PL.
DB 2 9.5引入了对SQLPL中的阵列数据类型的支持,以便帮助解决类似上面所述的那些应用程序开发问题。
DB2 9.5 introduces support for array data types in SQL pl to help with application development issues like those described above.
因此,不必担忧生产数据库将会有多大—为获得高性能而所需的磁盘阵列能够很好地容纳它。
Therefore, there is no need to worry about how large the production database will be — it will fit very well on the disk array that will be needed for performance.
例如,IBMDB 2融入了数据压缩特性,这让电信公司可以用更少的磁盘阵列存储数据。
IBM DB2, for example, incorporates data compression features that enable telcos to store data on fewer arrays.
清单6中的数据反映三个月内磁盘阵列中数据的增减。
Listing 6 contains data that reflects data growth and reduction contained on disk arrays over a three-month period.
与阵列的varchar表示相比,DB 2阵列数据类型具有显著的高性能。
DB2 array data types yielded significantly higher performance compared to varchar representations of arrays.

Given a microarray data set, articulate all the sources of error in measurement and find them in the particular data set.
后一转换允许阵列中的数据源其他表中的数据联接,以及允许SQL的set - at - a - time语义用于表示为阵列的集合。
The latter conversion allows the data in the array to be joined with data in other tables, and allows the set-at-a-time semantics of SQL to be applied to collections represented as arrays.
