標(biāo)題: Are there any differences between 'tier' and 'layer'? [打印本頁] 作者: mxh0506 時(shí)間: 2009-12-2 20:14 標(biāo)題: Are there any differences between 'tier' and 'layer'? 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?作者: 老郭 時(shí)間: 2009-12-2 21:35
tier和layer是近義詞。
