Data quality no longer sits on the shelf as a luxury, nice-to-have item; instead, it has become a key operational element for businesses.
数据质量并非华而不实，它已经成为业务的关键操作要素。
Key-values Stores. The main idea here is using a hash table where there is a unique key and a pointer to a particular item of data.
KV存储的主要思想是一个哈希表，每个item有一个主键和特定的数据值。
So this begins with the data in the people variable; it then moves to the item called programmers and pulls off the first record ([0]); finally, it accesses the value for the lastName key.
所以，这行代码首先访问people变量中的数据；然后移动到称为programmers的条目，再移动到第一个记录([0])；最后，访问lastName键的值。
The key produced by the key-function is used to encrypt every data item, so this key-function is very important for the security of the data.
密钥生成函数产生的密钥直接对数据库中每个数据项进行加密，因此该函数对数据的安全具有非常重要的作用。
This article describes a new dynamic key-function based on data item encryption and proves the security of this algorithm.
本文提出了一种新的基于数据项加密的动态密钥生成算法，并对此算法的安全性进行了证明。
The process of arranging data into some desired order according to rules dependent upon a key or field contained in each item.
根据由每项中所含关键 字或字段所确定的规则，将数据排列成某种所需次序的过程。
To retrieve data from the cache, you specify the key that the cached item was stored under.
要从缓存中检索数据，应指定存储缓存项的键。
Its characteristic is that the candidate set is adopted by the key word identifies, and at the same time transaction data is compressed by transaction and item.
该算法的特点是：项目集采用关键字识别，同时对事务数据进行事务和项目压缩。
To distinguish the correctness of the questionable data found out in single item check quality control, is a key technical problem in meteorological data quality control.
对于气象资料质量控制中单项检验为可疑的数据，如何进一步判别它的错误与正确，是气象资料质量控制中的一个重大技术问题。
