Difference between “Layer” and “Tier”

Many times we use Layer and tier simulatneously while explainging any architectural things in problem domain.

Somewhere on the web I got a very nice differentiation which seems to get the meaning behind these words.I thought its good to share this with you here..

difference between a “layer” and a “tier” A “layer” is a logical representation, whereas a “tier” is a physical representation. This means that a layered framework can reside on one sole machine — i.e. the DataAccess, Business and Presentation code reside on the same machine — or we can spread each layer to another machine so that you get multiple physical “tiers.”

Completing 1 yr of 7/11

Today is 11th July. Last year this day played havoc in my beloved Mumbai city.Many people were get injured in train blasts.
But Hats off to Mubaikars and cheers to their spirit,The local people be it a taxiwallah, the slum people or co-passenger of other train all rushed and helped victims to get medical treatments or get their messages conveyed to victims loved onces.

The very next day started as if nothing was happened. The same rush to locals same hassle-bussle and lively raliway stations. It can not happen elsewhere in the world.

“Amachi Mumbai is the best.”

This post is tribute to those people who had suffered from life-threatening injuries and even lost their lives.May God bless them!
