What Is n-Tier Architecture? | Scott Duffy

What is n-Tier Architecture? A 3-minute overview of what that term means, and the difference between 2-tier, 3-tier, and 4-tier architecture. How an application is divided across boundaries (both software/process and hardware).

This was perfect. It helped me understand the basics of N-Tier. Now I can go forward

[samuelsouza]

Very good. Excellent explanation. Thank you very much

at 0:43 I don't follow you anymore because then you start to mix tiers and layers. Layers describe logical groupings in a static view while tiers describe physical groupings in a runtime view - or physical distribution of various software packages. So layers is logical separation and tiers physical separations. This means that a 5 layer software package can end up as one tier.

There are more tiers.

For example, in JEE there is a presentation tier (for servlets and JSP), and client tier is the browser(and JSP as well I think)

I have a question my existing project is about ordering and delivery management. The system combines w/ customer app for ordering, driver app for delivery task, GPS tracking using arduino that sends data to main server (SMS/Web control), and the main website that monitors the order, delivery and tracking. What is the best n-tier architecture setup for this?

[ArunraajSingh]

is "Database Tier" just a database?
or the layer where we do write CRUD logic?

[amberahmed]

what is Tier 1 architecture?Please explain

[jennyl]

Why must the world wide web use n-tier architecture?

[lwazimarhawu]

is an n-tier an expanded multi-tier design?

Finally, someone who isn't Indian.
