非关系数据源的特征都封装在包装器中。
Characteristics of the non-relational data source are encapsulated within the wrapper.
对于非关系数据源来说，此数据结构基于数据源的特定格式。
For non-relational sources, the data structure is based on the data source's specific format.
不过，可以很容易地将它们映射到其他数据源，其中包括非关系数据源。
However, they could have easily been mapped to other data sources, including non-relational data sources.
OLEDB的目标（就像它之前的 ODBC 的目标）是提供对各种关系和非关系数据源的透明的访问。
The goal of OLE DB (as was the goal of ODBC before it) is to provide transparent access to a variety of relational and non-relational data sources.
RPD操作符中的远程访问计划是由包装器构造的，其中包含为调用来自非关系数据源的远程请求所需的规范。
The remote access plan contained in the RPD operator is constructed by the wrapper and contains the necessary specification to invoke the remote request from the non-relational data source.
除了上面的限制外，对于非关系昵称上的MQT，定义MQT的sql语句对于涉及的非关系数据源必须是合法的。
In addition to the restrictions above, for MQTs over non-relational nicknames, the SQL statement defining the MQT must be valid for the non-relational data sources involved.
对于其他数据源(比如非关系数据)或是其他的数据库访问技术(比如LINQ toSQL)来说，ADO.NET Data Services又提供了一种机制将这些数据源建模为实体和关系(比如通过EDMschema描述)并将其暴露为数据服务。
LINQ to SQL a mechanism is provided which enables any data source to be modeled as entities and associations ie. described using an EDM schema and exposed as a data service.
支持各种数据源，其中包括关系数据库管理系统(DBMS)、非关系DBMS、文件、XML文档和其他数据源。
Support for a variety of data sources, including relational database management systems (DBMSs), non-relational DBMSs, files, XML documents, and others.
这些数据源包括像mySQL之类的强大的关系数据库，也包括像Excel电子表格之类的非关系对象。
These data sources range from powerful relational databases such as mySQL to non-relational objects such as Excel spreadsheets.
