这通常涉及应用程序层移植和数据库对象迁移。

It typically involves application layer porting, and database objects migration.

数据库迁移活动的目的是确保相同的应用程序层能够与另一个RDBMS交互。

Database migration activity is done to ensure that the same application layer is able to talk to a different RDBMS.

因此，虽然对象名称正在向上迁移到逻辑层，但是队列管理器、通道、进程和其他系统名称正在向下转移，更接近物理基础结构层。

So while the object names are migrating up into the logical layer, the queue manager, channels, processes, and other system names are being driven down closer to the physical infrastructure layer.
