One of the secrets of success for mapping objects to relational databases is to understand both paradigms and their differences, and then make intelligent trade-offs based on that knowledge.
使对象-关系数据库之间的映射成功的一个秘诀就是理解这两种范例和它们的差异，然后基于这些认识来进行明智的取舍。

Next, you need to define how the actions are constructed from intermediate objects and the mapping from the intermediate object fields to the action fields.
下一步，您需要定义如何在中间对象的基础上构造操作，以及定义从中间对象字段到操作字段的映射。

You can write separate code that loads the relevant EMF resources and invokes the mapping engine on the model objects, but in this example everything is done for you in a transparent way.
你可以分开编写加载相关的EMF资源和对模型对象调用映射引擎的代码，但是在这个例子中所有任务的完成都是透明的。
As we noted earlier, the map parameter mapping type requires you to specify a business object map that handles the mapping between the attributes of two business objects.
正如我们在前面指出的，映射参数映射类型要求您指定业务对象映射，此映射处理两个业务对象的属性之间的映射。
Mapping has been improved to support very large business objects.
映射已经过了改进，以支持超大型业务对象。
The object relational mapping technology lets you map relational databases to objects.
对象—关系映射技术允许您将关系数据库映射为对象。
The vendor product is quite flexible and provides a mapping mechanism, via XML, that permits custom client objects to be mapped to the vendor's specific channel implementations.
该产品非常灵活，并且通过XML提供了一个映射机制，允许将自定义客户端对象映射到与厂商的特定渠道实现。
Note that creating this type of automated mapping process may only make sense if there are many objects in the model that need to be mapped or if it's difficult to manually identify them.
注意，只要在模型中存在大量需要进行映射的对象或难以手动识别映射的情况下，创建这种类型的自动化映射流程才是有意义的。
In such a design, updates are applied to objects and it is the responsibility of the mapping layer to migrate those changes to a relational database.
在这样的设计中，更新被应用到了对象上，映射层的职责就是将这种变化反映到关系数据库中。
Further, if your code USES objects, there's a tax-incurred mapping flat rows to objects.
此外，如果代码使用对象，则有指向对象的导致负担过重的映射平面行。
For mapping between business objects, you need a submap, as we will describe shortly.
对于业务对象之间的映射，您需要一个子映射，很快我们就会讲到这一点。
If the object model for your application doesn't translate easily into the relational model, you'll have quite a challenge mapping your objects to tuples and back again.
如果应用程序的对象模型不能够方便地转换到关系模型，那么在将对象映射到元组以及将元组映射回对象方面，会碰到一定难度。
They plan to create new kinds of unit cells and are also seeking new mapping techniques that allow those cells to be positioned over complex objects.
他们计划创造新型单位晶格并寻求新的能使这些晶格可以定位在复杂物体上的映射技术。
Look at the simplest SQL data binding task: mapping an object that doesn't refer to any other objects to a single table.
最简单的SQL数据绑定任务：把没有引用其他任何对象的对象映射到一个表。
Once the mapping is done, you can manipulate mapped objects as normal objects and easily submit changes back to relational database without writing complex data access logic.
一旦完成映射，您就可以将他们当成普通对象来处理，无需编写复杂的数据访问逻辑就可以轻松地将更改提交回数据库。
Using string types enables you to reuse the relationship in any mapping between business objects that need a state name to state code mapping between string-typed properties.
通过字符串类型，如果业务对象之间需要字符串类型的属性之间的州名称到州代码的映射，则可以在这些业务对象之间的任意映射中重用此关系。
The approach we take here removes the need for the whole first aspect because, instead of mapping the XML into native objects, we have made the XML a native object that can be used as is.
我们这里所采用的方法将去除了在第一个方面的需要，因为这时我们已经将XML作为一个直接使用的本机对象，而不用再次的映射操作。
BOM to XOM mapping is used to implement the synthetic objects.
bom到xom的映射用于实现合成对象。
Step 7: Define mapping from intermediate objects to actions.
步骤7：定义从中间对象到操作的映射。
