Two-tier architecture actually has got three parts which are client, server, and protocol the protocol links the gap between the client and server tiers the two-tier design is very effective for network programming as well as for gui programs, in which you can allocate functionality to the host. Experts often contrast a two-tier architecture to a three-tier architecture, where a third application or business layer is added that acts as an intermediary between the client or presentation layer and the data layer. Websphere® application server provides the application logic layer in a three-tier architecture, enabling client components to interact with data resources and legacy applications collectively, three-tier architectures are programming models that enable the distribution of application. N tier architecture includes all advantages of the 3-teir model since its an expansion of the 3-teir methodology mainly the performance is increased due to off-load from the database tier and the client tier, enabling it to suit medium to high volume industries (kambalyal 2010. At chrysler, 13 percent of its 26,000-worker us labor force makes the lower, tier-two wage, but marchionne expects the ratio to soar to 25 percent or more by 2015 when the new 4-year contract with the uaw, finalized on wednesday, expires.

Basically at high level we can say that 2-tier architecture is client server application and 3-tier architecture is web based application below we will concentrate on the difference between two-tier and three-tier architecture, what all advantages and disadvantages they have. Some of them are 2-tier architecture, 3 tier architecture, 4 tier architecture and n tier architecture 2-tier architecture in 2-tier, the application logic is either buried inside the user interface on the client or within the database on the server (or both.
3 tier architecture all the three different layer's distribute in three different places it's not necessary to put three different places also you can make the developer system as a web server,database,and all the gui related functionality early day's all the atm machine transaction done using this feature. This video will explain differences between two tier achitecture and three tier architecture with help of real life example. A two layer architecture is usually just a presentation layer and data store layer these can be on 1 tier (1 machine) or 2 tiers (2 machines) to achieve better performance by distributing the work load. Advantages of 3 tier architecture the advantage of a 3-tier system is that the contents of any of the tiers/layers can be replaced without making any resultant changes in any of the others for example: a change from one dbms to other will only involve a change to the part in the data access layer.
Report on 2- tier and 3- tier architecture software environment, future of the systems and the suitability of the applications (a)2 tier architecture it is functionally defined as an application architecture model that detach a code base from data base management system (dbms)the server has a client pc and a database server architectural layout a [. Two-tier client server architecture uses only two sets of computers, one set of clients and one set of servers three-tier architecture uses three sets of computers in this case, the software on the client computer is responsible for presentation logic, an application server is responsible for the application logic, and a separate database. A 3-tier application is an application program that is organized into three major parts, each of which is distributed to a different place or places in a network the three parts are: the workstation or presentation interface the business logic the database and programming related to managing it in.

Database management system – introduction | set 1 dbms 3-tier architecture dbms 3-tier architecture divides the complete system into three inter-related but independent modules as shown in figure 1. Three-tier architecture, the two-tier system has no middle tier, and this tight coupling causes the application to be fast (baabtracom, 2013) a user uses the program on their client machine to connect to the database directly and tell it what information to provide or update the database server.
Three-tier architecture emerged to overcome the limitations of the two-tier architecture in the three-tier architecture, a middle tier was added between the user system interface client environment and the database management server environment. Versions of ektron that were previous to 85 featured two tier architecture, in which the application and presentation tiers resided on the same server in three-tier architecture, you can locate the application tier in the client’s environment or an ektron hosting environment this represents a true separation of the web server from the database. Two-tier three-tier or multiple tier the idea of providing this tier base architecture is to secure multi-tier application environment there is no specific definition of two-tier or three-tier firewall.
