1.Django comes with its own object-relational mapper (ORM) library that supports dynamic database access through a Python object interface.
Django提供了自己的对象关系型数据映射组件（object-relationalmapper，ORM）库，它可以通过Python对象接口支持动态数据库访问。
2.The mapper script is shown in Listing 4 (with some comments and white space to give it a bit more size).
如清单4中所示的mapper脚本（通过一些注释和空白区域可给与其大一点的大小）。
3.QA Mapper enables the creation of project specific and secure test data sets which can be easily maintained through a web-based interface.
QAMapper能够创建可以通过基于web的接口简单地维护的具体工程的且安全的测试数据集。
4.SQLObject is the object-relational mapper (ORM) library that allows you to develop database-persistent Python objects.
SQLObject是对象关系映射器（ORM）库，它让我们可以开发数据库持久的Python对象。
5.The mapper function effectively strips the IP address out of each line and returns it with a value of 1.
mapper函数提取出每行中的IP地址并返回它和值1。
6.Otherwise, you create a new entry in the hash for the word, and then load the count (which should be 1 from the mapper process).
否则，您需要在该单词的hash中创建新的条目，然后加载计数（应该是来自mapper过程的1）。
7.To account for these lengthy URLs, the URL_Mapper_File allows you to specify default values for each parameter in the URL.
若要说明这些长的URL，则可以使用URL_Mapper_File来指定URL中的每个参数的缺省值。
8.The font mapper transforms the value into device units and matches its absolute value against the character height of the available fonts.
字体映射器将值转换为设备单位，并将它的绝对值与可用字体的字符高度相匹配。
9.The Mapper pattern is a way to direct a bounded infinite set of resource requests to a single physical point of code.
Mapper模式特点如下：将无限的资源请求转向一个单独的物理节点。
10.You can think of XMLBeans as an object-relational (OR) mapper -- but for XML files rather than relational databases.
可以将XMLBeans看作对象-关系（OR）映射器，但这是针对XML文件而非关系数据库而言的。
