Course Outline
The persistence layer is an essential feature of any enterprise application used to store and retrieve objects from a database.
It’s quite common for persistence layers to be developed in-house to cope with issues as they arise. However, if changes are made to the underlying database schema, it can be time-consuming and thus expensive to propagate the changes throughout the application.
Hibernate can be used to solve these problems, providing a relatively simple and powerful object-relational persistence framework for Java applications, and is often used alongside Spring and Struts frameworks.
Course Content
Our intensive hands-on Hibernate training course will provide delegates with the skills necessary to develop Java applications that rely on Hibernate for persistance solution. Available as a public or closed course at our London training centre, or can be tailored to your team's requirements and delivered onsite as a bespoke, customised training course.
This course has been developed for real-world, commercial scenarios by our expert instructors. See below for detailed syllabus. If you have a technical question, please email sales@jbinternational.co.uk
