Java Hibernate Programming Course

This course teaches students the most popular object-relational mapping framework for Java environments. Object relational mapping in large enterprise applications is difficult. The task is so difficult that the problem of storing and retrieving objects to a relational database has its own name – impedance mismatch. In this class, students learn object-relational mapping concepts and the various issues and options available in Java to address object persistence. With these fundamentals, the course then explores the basics of Hibernate object persistence and configuration. It also digs into the details of Hibernate mapping, queries, transactions, and concurrency. After taking this class, developers will be able to build faster, more flexible and easier to maintain application persistence layers and overcome impedance mismatch with the Hibernate framework.
