The purpose of xml_objects is to transform an XML document into a two dimensional grid representation that can more easily be stored in a relational database.
Dojo网格的数据源可以是数据库、REST服务或者是JSON文件。
A data source for Dojo's grid can be a database, a REST service, or a JSON file.
网格是根据EnterpriseReplication (er)构建的，er是一个基于日志的工具，用于在IBMInformix数据库服务器之间复制数据。
Grids are built on Enterprise Replication (er), an asynchronous log-based tool for replicating data between IBM Informix database servers.
网格数据服务工厂使网格数据服务的创建能够存取和更新数据库。
The factory enables the creation of Grid data Services to access and update databases.
就像城市地图按网格分成一些区一样，数据库管理器使用分区键来确定数据所存储在的位置(数据库分区)。
Just as a city map is organized into sections using a grid, the database manager USES a partitioning key to determine the location (the database partition) where the data is stored.
网格数据服务使得用户通过网格基础架构能够存取数据库。
A data service enables databases to be accessed through the grid infrastructure.
您无需编写任何数据库连接语句，因为创建网格数据服务时ogsa - DAI在后台会为您进行相应的数据库连接。
You don't need to write any database connect statements. OGSA-DAI executes the appropriate database connection for you behind the scenes when creating the Grid data Service.
在本文中，我们将配置网格数据服务工厂来涵盖将要被存取的数据库名，以及被ogsa - DAI用于存取db 2UD B数据库的用户ID和口令。
We will configure the factory in this article to include the name of the databases that will be accessed and the user ID and password that OGSA-DAI will use to access DB2 UDB databases.
新的系统则是将个人信息的变更写入到网格中，然后使用write-behind技术将这些变更推到数据库中。
The new system writes profile changes to the grid and then these changes are pushed to the database using the write-behind technology.
一旦数据库被加载，数据网格代理(data grid agents)就会预先加载缓存。
After the database is loaded, the cache is preloaded using data grid agents.
这一方式具备的明显优势就是能够减少数据库调用，从而减少事务负载，更快地访问网格（grid）中的对象。
The obvious advantage of this scenario is reduced database calls and therefore reduced transaction load and faster access to objects in the grid.
网格能够随着规模的变化提供更短的响应时间，因为变化会单独地提交到网格，即使数据库被停止，事务仍然能够提交。
The grid can offer reduced response times as it scales for changes because changes are committed to the grid alone and transactions can commit even if the database is down.
IBM已经为未来几年制定了一个路线图，包括对Hadoop的支持、不同温度带数据(multi - temperature data)、以及网格到非数据库源的扩展。
IBM has laid out a road map for the next several years that includes support for Hadoop, multi-temperature data, and the extension of grid to non-database sources.
