【正文】 corporation work system is a very huge and plicated system, it not only providing the basic operation for a series application such as synthesizing the information management and transacting automation etc,but also can provide various application service,making information on time, and delivering accurately to the each system. The corporation engineering developments inside applied the LAN technique that is the important branch of the work techique to construct and manage .So this graduate design lesson will take the construct process of the LAN of corportation into practice,and provide theory and practice guidance for the construct of corporation work.
