Multi DIMENSIONAL CLUSTERING (MDC) - organizing data in table (or range of a table) by multiple key values.
像SSIS这样的ETL工具就可以实现这些功能，如，在不同的系统间进行数据的移动、数据的再格式化、完整性校验、关键值查询、衍生跟踪等，SSIS也证明了它是一个有能力和有着多方面用途的ETL工具。
ETL tools like SSIS can perform these functions such as moving data between systems, reformatting data, integrity checking, key lookups, tracking lineage, and more.
INSERT_UPDATE将新的输入数据添加到表中，或者用具有匹配主键值的输入数据更新现有的行。
INSERT_UPDATE adds new input data to the table, or updates existing rows with input data that has matching primary key values.
这是一个键值，如同数据库里的键结构，唯一地标识每一个高速缓存条目。
This is a key, similar to a database key structure that identifies a particular cache entry as unique.
这些键值可以存储在现有的数据表中或者存储在单独创建的称作外键表的表中。

字段中的默认值很可能是通过使用upc符号作为键值从一个数据库或运营系统中检索到的。
The default values in the field would most likely be retrieved from a database or operational system, using the UPC symbol as the key value.
因此，消息模型(它们定义流程与其支持服务之间的合约)占用的数据非常少，只使用了少量关键值。
The message model, which defines the contract between the process and its supporting services, is therefore minimal, based only on a small number of key values.
它们为ID属性使用数据库生成的主键值。
They use database-generated primary key values for the ID attribute.
添加服务器名称、数据库名称、用户ID和键值。
在满足筛选器条件的每个行中，数据库服务器将对键应用哈希函数，并探测哈希表以查找匹配的键值。
For each row that satisfies the filter condition, the database server applies hash function to the key and proves the hash table to find a match.
同样，关系数据库中的行也是惟一的，它们由主键值标识。
Similarly, relational database rows are also unique, so long as they are identified by primary key values.
该层从请求中提取关键值，请求将会传递到处理层，后者用于检索xML文件中相关的测试数据。
This layer extracts key values provided in the request that will be passed to the process layer responsible for retrieving the associated test data XML files.
它不适合更复杂场景，理由很明显，数据契约太松散，它无法确保两层之间的键值对不出现错误的匹配。
The reason it doesn't scale to more complex scenarios is fairly obvious, the data contract is too loose and it becomes hard to ensure there are no mismatches in key, value pairs between the two tiers.
Copy阶段允许在这些阶段之间传递数据，而不引入任何操作冲突，因为每个阶段处理键值的方式都不一样。
The Copy stage allows data to be passed between these stages without introducing any operational conflicts due to the way each stage treats key values.
带有RecipeJAUS步骤信息包序列的输出文件作为一个JAUSRecipe表记录存储在RCS数据库中，该记录的键值在编译结束时显示在控制台中。
The output file with the RecipeJAUS step packet sequence is stored in the RCS database as a JAUSRecipe table record whose key is displayed in the console at the end of the compilation.
关系数据库使用结构化查询语言(Structured Query Language,SQL)以便从多个表和列中提取信息，但是键值存储仅限于对键列的操作。
Relational databases use Structured Query Language (SQL) to pull information from multiple tables and columns, but key-value stores are limited to operations on the key column.
与不重要的数据库相关的日志消息，这是Samba使用的键值存储。
Log messages relating to trivial databases, which are key-value stores that Samba USES.
Cookie也许仅仅由一个简单的键值组成，该值用于解锁存储于公司数据库中有关此用户的大量信息。
The cookie may consist of nothing more than a simple key value that unlocks reams of information about this user stored in the company's databases.
这是有意义的，因为一般希望知道某个数据值(而不是键值)是否在dictionary中。
This makes sense because you generally want to know whether a data value — rather than a key value — is in a dictionary.
进一步地指定独一的主键值（标为 @Id注释），取决于生成值的数据库。
To specify further that the unique key attribute (marked with @Id annotation) will rely on your database to generate its value.
如果您熟悉关系数据库，例如IBMDB 2、MySQL或PostgreSQL，则相比之下您将发现键值存储非常简单。
If you are familiar with relational databases such as IBM DB2, MySQL, or PostgreSQL, then you will find key-value stores primitive in comparison.
可以看到，创建dictionary需要键值和数据值。
As shown, creating a dictionary requires key values and data values.

InsertJSON expects two input parameters: the unique key value for primary key and the row data in JSON format.
insertJSON需要两个输入参数：主键的惟一键值与json格式的行数据。
InsertJSON expects two input parameters: the unique key value for primary key and the row data in JSON format.
