Course Description
The Oracle Commerce Platform consists of a data and presentation layer. Understanding the data relationships, and how that data is accessed is a fundamental skill for any developer. In this course, you will be able to describe the data relationships in the Oracle Commerce Platform, create data sources, describe form handling mechanisms, and write robust JSP. This course is one of a series in the Skillsoft learning path that covers the material for the Oracle Commerce Platform Fundamentals for Developers.
