ABSTRACT:

In general, web applications have either two-tier orthree-tier client/server architectures. The two-tier architecture was developedin the 1980s from the file server software architecture design. Its intentionis to improve usability by supporting a form-based user interface. It alsoimproves flexibility and scalability by allocating the two tiers over thecomputer network. The three-tier (multi-tier) architecture emerged in the1990s, with a middle tier in-between the user interface and the data managementserver. This middle tier provides process management and is the place where thebusiness logic and rules are executed. Compared with the two-tier architecture,the multi-tier architecture increases the scalability and flexibility of webapplications.
