CS 412 - Enterprise Software Systems

 Moodle Page

Course Description

This course starts out by introducing the concept of Enterprise Software by going over its unique properties and requirements. The popular and widely-accepted J2EE specification is used throughout the course to demonstrate the basic elements of Enterprise Software Systems.

The course will draw comparisons between different software development approaches in terms of design, initial development cost, maintenance, troubleshooting, complexity and training.  J2EE/Application server technologies will be compared with the other commonly used technologies.
 

We will discuss how the J2EE spec is shaping the software industry and analyze the factors that are making many companies invest so much in this new technology.

This course particularly concentrates on the middle tiers that are located between the Database Management System and the Presentation Tier. Remote Method Invocation (RMI), Enterprise Java Beans (EJB), Persistence and Transactions are some of the main topics that will be covered in the course.
