Design and Implementation of Teaching and Management Systems in Higher Vocational Schools With Four-tier Architecture Based on .NET Framework and Browser/Server Mode

The design and implementation of teaching and management system in higher vocational schools with four-tier architecture is introduced according to actual needs and characteristics of higher vocational schools in this paper. Based on .Net 4-tier B/S architecture, it adopts Web layer, business logic＂ layer, business entity layer, data access layer to construct the system, and the design of the functional model is discussed . The concrete irnplementing tactics of four-tier structure based on .NET are discussed, meanwhile, application program model of basing on four-tier structure and the key technologies of developing are given.
