I’m quite confused about these two words. In the following sentences:

1. As you will see, data adapter objects function as a bridge between the client tier and a relational database.

2. To showcase the usefulness of the disconnected layer, you will be updating the data library with new namespaces that make use of disconnected types.

it seems that they mean the same thing. Are there any differences between them?

tier和layer是近义词。

tier有层级的意思,一般会有多个tier,不如士农工商,每个都是一个tier,一层压一层

layer就是层。可能就一层。就算是多层,也不强调级别。
