Hibernate Training in Chennai

Learn how to use Hibernate from beginner level to advanced techniques which is taught by experienced working professionals. With our Hibernate Training in Chennai you’ll learn concepts in expert level with practical manner.

Hibernate is a high-performance Object/Relational persistence and query service framework. It works in form of ORM. ORM stands for Object-Relational Mapping (ORM) is a programming technique for converting data between relational

databases and object oriented programming languages such as Java, C# etc. Hibernate not only takes care of the mapping from Java classes to database tables (and from Java data types to SQL data types), but also provides data query and retrieval facilities. Advantages of Hibernate

are

  • An API to perform basic CRUD operations on objects of persistent classes.
  • A configurable facility for specifying mapping metadata.
  • A technique to interact with transactional objects to perform dirty checking, lazy association fetching, and other optimization functions.
