本文简单介绍了三层结构与传统的两层结构在计算机系统应用中的区别,并列举了一个简单的实例清楚阐明了三层结构在广域网、大系统、多种数据库中是如何优化资源、并解决两层结构所难以解决的系统资源共享、交互问题。本文具有较强实用性。
This article gives a brief introduction of the differences between the three-tier architecture and the traditional two-tier architecture in computer systems. A simple example is given to illustrate clearly how the three-tier architecture optimizes resources in wide area networks, large systems, and multiple databases. Solve the two-tier structure is difficult to solve the system resource sharing, interaction problems. This article has strong practicality.
