Technology>>Java/J2ee

NIVANSYS has invested in training resources and developing framework combining best design practices for developing applications based on J2EE, this enables a developer to jump-start into development right away, without worrying about the intricacies behind database connectivity, File I/O, error handling, session and application management.

The framework is created to help speed up development time and build web applications with fewer complexities. Using these frameworks, majority of the efforts is focused on the business logic or functionality implementation.

Most J2EE web-based enterprise applications are split into three logical tiers, Presentation Tier, Business Logic Tier, and Enterprise Information System Tier.

The presentation tier, which aims at presenting the business information to the user, is implemented using Servlets, JSPs and HTML/WML.

The business tier, where core business mechanisms are implemented, is usually encapsulated in EJBs (Enterprise Java Beans).

The enterprise information system tier, which represents different kinds of legacy systems, database servers, etc is usually accessed through the JDBC API and other standard interfaces provided by the J2EE Connector Architecture.
