A Preliminary Study on Visual Studio example: Fitch and Mather 7.0

Since the company wants to build a general system recently, it does a simple research on Fitch and Mather 7.0 during idle time.
Fitch and Mather 7.0 documents are available on MS-help: // Ms. msdnqtr.2003feb. 2052/f_and_m/html/vxorifitchmather70overview.htm:
I will mainly talk about the following points:
Deployment:

The Application Center cluster web layer and BLL and Dal are used in different clusters,
The web layer and BLL layer are accessed through. Net romote

Bll and Dal direct access (because the two are closely linked)

Personal Opinion:
This deployment method is suitable for application systems that process a large number of businesses and have complicated business logic,

Dal layer:
base class inherited from system. enterpriseservices. servicedcomponent
in this way, all data access components have the event function.
other features:
BLL layer:
base class inherited from marshalbyrefobject
enable remote call completion
conclusion:
reference:
1: deployment method.
2: The Web layer and BLL are separated by remote calls.
verify the web layer!
