3 Tier Architecture

by Ivan C
What is a three tier architecture? A three tier architecture helps by dividing a website production into 3 distinct layers. Each layer has its own responsibilities and each one is needed for the others to work. The three tier architecture, also known as n-tier architecture, is separated by the layers known as the presentation layer, logic layer, and data layer (Ortiz). The presentation layer includes the user interface which is made to be understood by the user. The logic layer is responsible for the logic behind the user interface. This layer can include web servers and other side programs. The data layer is used to store and retrieve information in and from a database. Using a three tier architecture has its advantages such as being able to replace a layer, for example the database in the third layer, without there being any changes in the process, and the work load is divided equally (3Tier). Overall these articles help me remember a few things about three tier architecture. It explained a few advantages over the one and two tier architectures and provided good illustrations. I am still confused about how each one precisely works but I think its logic that could easily be understood.
