How do I structure my application into layers?
« on: July 25, 2016, 01:04:56 PM »
The term N-Tier may or may not be familiar to you, but it’s definitely a concept that’s worth being aware of, as it makes a very useful measure of the design of your application. The “N” means “some number of”, while “tier” refers to the layers in your application being like tiers on a wedding cake.

Let’s step back into the past for a moment. In the old days of client-server computing on corporate networks, applications shared by multiple users were generally built with two tiers: a central database or file server, and a desktop application mthat accessed the central resource. This worked well for small groups of users, but as applications were distributed across regional and international networks and user bases grew, all sorts of problems ensued. The database might be overloaded, client side upgrades and maintenance became more expensive, and network latency delivered poor performance to users—and this was before people thought
about putting their applications online!
