Course Description

  
Java Enterprise Edition (JEE) is a powerful platform for building web and database-driven applications. This course provides the information you need to design and build your own data-driven web applications. You'll learn the details of the core JEE Web and database technologies and how to leverage the strengths of each. You'll also be introduced to other important web-based technologies such as creating REST services with JEE. Throughout the course, students will create code for a online store. Students will learn not only specific topics and APIs but also how to fit the pieces together into a complete application.
