摘要
针对数据库应用系统中两层结构和三层结构的优势与不足,设计了两种体系结构并存的解决方案。利用DCOM实现隐藏逻辑代码和复杂的企业应用逻辑运算规则,部分客户用ADO直接与数据库服务器相连,以便处理大量信息时降低网络通信量,从而实现既有两层结构的数据处理快速的优势,又有三层分布式的不必维护大多数客户端的方便的应用模式。
Aiming at the advantages and faults of two-tier or three-tier architecture in-database application system, this paper presents a solution of application system with two architectures. The solution realizes hiding logical codes and complicated logical computing rules of enterprise application with DCOM. A part of clients communicate directly with database server using ADO, which would lower the communication traffic of computer network in handling a large amount of information. This application system is of the two-tier＇ s advantage of processing data quickly and the three-tier＇ s convenience of avoiding maintenance of most clients.
