Technologies used to develop Enterprise Application

  • User Interface layer (Presentation Layer) - AWT, Swing, HTML, JSP, Velocity Framework
  • Business Processing Layer - Servlets, JSP, EJB
  • Data Storage and Access Layer (Persistence Layer) - JDBC, EJB

For eg: Java provides the enterprise solutions whereas its editions serve different purposes.

  • J2SE - Introduction, OOP, String Manipulation
  • J2EE - Servlets, EJB, Middleware Service, JSP
  • J2ME - Wireless Messaging, Mobile XML etc.

Java is widely used for developing enterprise applications (EA) because:

  1. Learning Curve
  2. Java has a vast array of libraries, frameworks, tools and server provider.

Enterprise Application vs Desktop Application vs Web Application

a. Desktop Application

  • Runs on single tier architecture.
  • All the presentation logic, business logic and data storage and access logic resides in a single machine.
  • Moreover, it can be part of network but the application and its database stay in the same machine.
  • It doesn't support multiple users concurrently.

b. Enterprise Application

  • It normally includes more than a single tier.
  • Multiple users can access the application at the same time. (Multiple concurrent users)
  • It have client tier (java client, browser, mobile based client), representation tier (JSP), business logic tier (EJB), and data storage and access tier (JDBC).
  • It can be distributed system.
  • It can be a web application or a desktop application.

c. Web Application

  • It is a web application that runs on a web server.
  • Web applications runs on a web server like Tomcat whereas desktop applications runs on a desktop machine and enterprise applications runs on a application server like Glassfish.
  • Web applications can be accessed by any browser.
  • It needs internet access to run.
