| 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。

| Abstract: | Aiming at the advantages and faults of two-tier or threetier 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. |
