物理数据页面读取次数。
逻辑数据页面读取次数
这样一个数据页面上可以保存最多的信息。
这意味着DB2按顺序在表空间上提取每一个数据页面到缓冲池。
This means that DB2 fetches every data page in the table space sequentially into the buffer pool.
FETCH节点使用这些 RID来定位表空间内的对应数据页面。
These RIDs are used by the FETCH node to position the corresponding data pages in the table space.
但是要注意，内联会极大增加数据页面的行大小，从而减少每个页面的行数量。
Note, however, that inlining significantly increases the row size on your data pages. This in turn decreases the number of rows per page.
数据页面的内容包括页面上的数据和有关页面上数据的信息(有时称为元数据)。
The content of a data page is both the data and information about the data on the page (sometimes called metadata).
这是因为，LOB这样的XML文档体积庞大，无法放到表数据页面的单个行中。
This is because XML documents, like LOBs, can be too large to fit within a single row on a data page of the table.
区段确定如何跨越多个容器进行数据分段，并确保一个容器里的数据页面是连续的。
Extents determine how data is striped across multiple containers and ensure that the data pages in a container are contiguous.
在db2缓冲池中数据页面也保持压缩的，为了潜在的重用允许更多的数据缓存在内存中。
A data page also remains compressed in the DB2 buffer pool there by allowing more data to be cached in memory for potential reuse.
通过dms表空间，DB2更加可以控制如何将数据页面物理映射到称作区段的磁盘空间分组中。
With DMS tablespaces, DB2 has more control over how data pages are physically mapped in disk space groupings known as extents.
然后通过FETCH节点获取合格的RID以提取来自表格空间的相应记录和数据页面到db2缓冲池。
The qualifying RIDs are then taken by the fetch node to fetch the corresponding records and data pages from the table space into the DB2 buffer pool.
使用Ajax，您可以确保当一个新数据页面正在被提取时，用户不必观看整个页面重载，而是只使用新数据集替代部分页面。
With Ajax, you can ensure that the user doesn't have to watch the entire page reload when a new page of data is being fetched, but instead just replace part of the page with the new set of data.
现在数据量比以前大得多，而且有时系统看上去已经崩溃了，但事实上只是一个页面跳转到另一个页面花的时间较长而已。
There's a lot more data now and it sometimes seems the system has crashed but, in fact, it just takes ages to go from one screen to the next.
如果没有新的数据要显示在页面上呢？
数据流与页面重新加载同步。
此时，您也许会困惑如何才能让描述数据呈现在页面内。
At this point, you might wonder how to get the description data to render in the page.

门户模型表示门户用于生成门户页面的数据。
Portal models represent the data that the portal USES to produce a portal page.

图3显示了数据输入页面的外观。
通过解析提要数据从页面获得项。
最后，调用查询现有记录和用数据更新html页面的函数。
Lastly, the functions that query the existing records and populate the HTML page with the data are called.
查找图中显示异常的页面数据。
通常，当前页面上的数据请求是基于前一个页面中的响应数据的。
Often, the data request on the current page is based on the response data from previous pages.
不再把实例数据写入页面，而是从服务器异步检索数据然后将其动态增加到页面模型中。
Instead of writing the instance data to the page, you'll retrieve it asynchronously from the server and then dynamically add it to the model on the page.
“假”数据不能代表真实数据在页面上会占据的空间。
"Fake" data doesn't represent the actual space on the page that would be taken up by realistic data.
数据块页面存储模型中的最小存储实体。
Data blocks Pages Smallest storage entity in the storage model.
点击Finish创建这个页面数据。
创建动态表单，提交数据无需页面刷新。
