Interoperability. 3-Tier architecture IV. Examples. ? Database: MSSQL, Postgres, Oracle, MySQL, etc. ? Middle Tier: C#, .NET, ASP, JSP, Java, PHP, C++, Perl N-Tier architecture I. More complex systems demand greater abstraction and interaction. ? Easy to generalize concept into N-tiers for as many layers as you.

All the applications should be developed using 3-tier or N-tier architecture in order to maximize access. • Publishing information to the web with HTI)lL or XML via Java PDF. Monochrome documents or drw. • Word Processing j. • Archive & Retrieval : • Workflow. • Multimedia. • Digital Publishing. • Pattern Recognition !
1 Dec 2000 Type 4 provides direct database access using a pure Java database driver. Due to the way type 4 drivers run on the client and directly access a database, running in this mode would imply a two-tier architecture. A better use of type 4 drivers in an n-tier architecture would be to have an EJB contain the data

Developing to Distributed N Tier Client/Server Applications. 5. The newer concept here is the so called three tier architecture or three tier client/server. It has also been called an n tier (because it could have more than three tiers), a multi tier, or Microsoft s term, the services based architecture. If we think about it in three
Why 3-Tier (N-Tier Architecture?) • Flexible applications. • Reusable code. – Code once, use many times. • Modularized. – You need only to change part of the code. – You can deploy only one part. – You can Test only one part. – Multiple Developers. • Different parts (Tiers) can be stored on different computers. • Different
N tier architecture means splitting up the system into N tiers, where N is a number from 1 and up. A 1 tier A 2 tier architecture is the same as a client / server architecture etc. The presentation tier consists of HTML, CSS and JavaScript, the application logic tier runs on a web server in form of Java Servlets, JSP, ASP.NET
