Next, bind each data node in the data instance to the XFDL items on the form.
接下来，将数据实例中的每个数据节点绑定到表单上的XFDL元素。
Once you drop the data node onto the control, it will become associated with that data.
将数据拖到控件上之后，它就与那个数据联系在一起了。
By binding the Name data node to the Name items on the form, the data can be synchronized.
通过将Name数据节点绑定到表单上的Name元素，数据就可以同步了。
You can also remove fields, change the labels, and change which data node the field is bound to.
还可以删除字段，修改标签或者改变字段绑定的数据节点。
When a data node is relevant, a browser will display any XForms controls associated with that node.
如果一个数据节点是相关的，那么浏览器会显示与这个节点关联的任何X Forms控件。
The administration node has a single database partition, and each data node has four database partitions.
管理节点具有单个数据库分区，每个数据节点都有4个数据分区。
You have finished creating the relationship between the items on the form and the data node in the data instance.
现在，已经创建了表单元素和数据实例中数据节点之间的关系。
Data locality: the client machine typically is not a data node. Allthe data accessed is remote and has to be read via the network.
数据分布：客户端机器一般都不是数据节点，所有的数据访问都是远程的，必须通过网络读取。
A "binding" connects an instance data node to a form control or to a model item constraint by using a binding expression as a locater.
通过将绑定表达式用作定位器，“绑定”将实例数据结点连接到表单控制或模型项目约束。
Definition: a "binding" connects an instance data node to a form control or to a model item constraint by using a binding expression as a locater.
定义：通过将绑定表达式用作定位器，“绑定”将实例数据结点连接到表单控制或模型项目约束。
For the partitioned database to function properly, you must configure the operating system environment, including users and groups, in the same manner on each data node.
为使分区数据库正常运行，必须在每个数据节点中以相同的方式来配置操作系统环境，包括用户和组。

Continue with the next steps, accepting the defaults, to add the Hadoop Data node instance.
继续完成接下来的步骤，接受其默认值，从而添加HadoopData节点实例。
Since the process of provisioning a Hadoop Data node instance is very similar to provisioning a Hadoop Master node instance, only the steps that are different, or require attention are described here.
因为预备HadoopData节点实例的过程十分类似于预备HadoopMaster节点，所以这里只描述不同的步骤或需要关注的步骤。
