Duration:   2 days
Audience Prerequisites

This course is for developers, architects, and designers who need to understand various Java data access technologies.

  • Developers
  • Designers
  • Architects
  • Consultants

Audience should know Java

Description
Java applications often need to persist data into a datastore, be it a relational database or file system. Java developers face several choices when it comes to data persistence: ad hoc serialization, entity beans, Hibernate, JDO (Java Data Objects), etc. Knowing these technologies is the first step towards making an intelligent decision.

This overview course helps you make that decision. It introduces you to all the popular data access technologies currently available and compares each one's advantages and disadvantages. Once you have made that decision, we have subsequent courses that cover each topic in greater details.

This is a hands-on course. About 40% of the time will be devoted to labs.
Objectives

Upon completion, students will be able to:

  • Understand Hibernate architecture
  • Understand JDO architecture
  • Understand EJB technology
  • Understand the pros and cons of various data access technologies
