Patterns for Three-Tier Client/Server Applications
نویسندگان
چکیده
The three-tier client/server architecture is an evolution of the traditional two-tier model, and is receiving increased interest, particularly for large business applications. The main difference is that in a three-tier architecture, most of the functionality is separated out in a middle layer, called application servers, as shown in figure 1. Also, each client can use several application servers, each of which in turn can work against several databases.

متن کاملClustering of Client-Sites in Three-Tier Database Architectures
Conventional two-tier databases have shown performance limitations in the presence of many concurrent clients. We propose logical grouping of clients (or clustering) as the means to improve the performance of collaborative networked databases. In this paper, we discuss a three-tier client-server database architecture (3t-CSD) featuring the above partitioning. The proposed clustering is based on...
