Teams need to be able confirm in an automated fashion that an end-to-end command was correctly processed and that the data was delivered at each middle-tier layer according to expected policies.
团队需要能够以一个自动模式确定一个端到端命令是否被正确处理，以及数据是否依据预期策略在每个中间层传递。
Response times are reduced and the scalability of the Document Manager middle-tier server is greatly increased since it is now doing only the work required to actually perform the user's request.
因为现在只进行实际执行用户请求所需的工作，所以响应时间减少了，DocumentManager中间层服务器的可伸缩性大大提高了。
Using trusted contexts provides greater control while using restricted, sensitive privileges, and allows middle-tier servers or applications to assert the identity of the user to the database server.
通过使用可信上下文，可以在使用受限制的、敏感的特权时提供更强的控制，并且使中间层服务器或应用程序可以向数据库服务器确定用户的身份。
By using XML natively in the middle tier, those same advantages are achieved in the middle tier and more importantly across both the middle tier and the database.
通过在中间层原生地使用XML，可在中间层(更重要的是跨中间层和数据库)实现这些好处。
This support in JDBC 4.0 means that XML can natively flow across the middle tier and the database without unnecessary mapping or performance overhead in both the database and the middle tier.
JDBC 4.0中的这个支持意味着：无需不必要的映射，XML就可以原生地在中间层和数据库之间流动，这也不会在数据库和中间层导致性能开销。
