Three Tier Applications • Client Server Application

Benefits of Three-Tier Architecture
• Three-Tier Architecture provides the following benefits.
• Business Logic Abstraction—Business logic can be encapsulated in the middle tier instead of in the database tier or front end, allowing portability across DB vendors and allow thin client (PC, Tablet, Smartphone etc)
• Scalability—Each tier can scale horizontally. For example, you can load-balance the Presentation tier among three servers to satisfy more Web requests without adding servers to the Application and Data tiers.
• Performance—Because the Presentation tier can cache requests, network utilization is minimized, and the load is reduced on the Application and Data tiers. If needed, you can load-balance any tier.
• Availability—If the Application tier server is down and caching is sufficient, the Presentation tier can process Web requests using the cache.

Weblogic - Timeline • Weblogic started in 1995 right before the dot com boom period.
• Created the first J2EE application server, namely WebLogic Application Server
• BEA Systems bought Weblogic in 1998
• Oracle bought BEA Systems in 2008

What is Weblogic? • WebLogic is a server software application that runs on a middle tier, between back-end databases and related applications and browser-based thin clients. • WebLogic Server contains Java 2 Platform, Enterprise Edition (J2EE) technologies. • J2EE is the standard platform for developing multitier enterprise applications based on the Java programming language. • The technologies that make up J2EE were developed collaboratively by Sun Microsystems and other software vendors, including BEA Systems.

What is J2EE? • Short for Java 2 Platform Enterprise Edition. J2EE is a platform-independent, Java-centric environment from Sun for developing, building and deploying Web- based enterprise applications online. • J2EE platform consists of a set of services, APIs, and protocols that provide the functionality for developing multi-tiered, Web-based applications. • Some of the key features and services of J2EE: • At the client tier, J2EE supports pure HTML, as well as Java applets or applications. It relies on Java Server Pages and servlet code to create HTML or other formatted data for the client. • Enterprise JavaBeans (EJBs) provide another layer where the platform's logic is stored. An EJB server provides functions such as threading, concurrency, security and memory management. These services are transparent to the author. • Java Database Connectivity (JDBC), which is the Java equivalent to ODBC, is the standard interface for Java databases. • The Java servlet API enhances consistency for developers without requiring a graphical user interface. 12/26/14 10 www.quontrasolutions.com
