Course Overview

h

The Architecting and Designing J2EE Applications course provides students with knowledge needed to use the Java 2 Platform, Enterprise Edition (J2EE platform) to create robust enterprise applications that allow for rapid change and growth. Participants gain an understanding of the strategies needed to create application blueprints that work well when implementing J2EE technologies. These strategies include effective decisionmaking through the use of systemic qualities (such as scalability and flexibility), J2EE technology blueprints and design patterns, and iterative and incremental development.

Skills Gained

• Make good use of J2EE component technologies to solve typical problems in system architecture
• Derive software systems using techniques outlined in the J2EE Blueprint and solutions defined in the J2EE Patterns Catalog
• Address quality-of-service requirements in a cost-effective manner using engineering trade-off techniques
• Describe the role of the architect and the products an architect delivers
• List and describe typical problems associated with large-scale enterprise systems
• Identify the benefits derived from using an iterative and incremental development process
