This month, we looked at the reasons behind three-tiered architectures and started to look into a basic implementation of an application that uses this architecture. As you can see, we can already create small text-mode applications. Next month, we will complete our implementation, giving us the skeleton for a simple appointment book using mod_perl/Mason and PostgreSQL. We will also discuss issues regarding the scalability of three-tier solutions, as well as some of the pitfalls.
