Hibernate supports Query cache and provide statistics about query and database status. 6) Provides Query Statistics and Database Status 5) Simplifies Complex Joinįetching data from multiple tables is easy in hibernate framework. So there is no need to create tables in the database manually. Hibernate framework provides the facility to create the tables of the database automatically. Before Hibernate, if database is changed for the project, we need to change the SQL query as well that leads to the maintenance problem. So you don't need to write database specific queries. It generates the database independent queries. HQL (Hibernate Query Language) is the object-oriented version of SQL. There are two types of cache in hibernate framework first level cache and second level cache. The performance of hibernate framework is fast because cache is internally used in hibernate framework. Hibernate framework is open source under the LGPL license and lightweight. Advantages of Hibernate Frameworkįollowing are the advantages of hibernate framework: 1) Open Source and Lightweight The javax.persistence package contains the JPA classes and interfaces. Java Persistence API (JPA) is a Java specification that provides certain functionality and standard to ORM tools. The ORM tool internally uses the JDBC API to interact with the database. It is a programming technique that maps the object to the data stored in the database. 1 DURGASOFT, 202,2 nd Floor,HUDA Maitrivanam,Ameerpet, Hyderabad -500038, 040 -64 51 27 86, 80 96 96 96 96, 9246212143 Core Java with SCJP/ OCJP Notes By Durga Sir Language Fundamentals 2 DURGASOFT, 202,2 nd Floor,HUDA Maitrivanam,Ameerpet, Hyderabad -500038, 040 -64 51 27 86, 80 96 96 96 96, 9246212143 Language Fundamentals Agenda : Rule 4: java. Hibernate implements the specifications of JPA (Java Persistence API) for data persistence.Īn ORM tool simplifies the data creation, data manipulation and data access. It is an open source, lightweight, ORM (Object Relational Mapping) tool. Hibernate is a Java framework that simplifies the development of Java application to interact with the database. It was started in 2001 by Gavin King as an alternative to EJB2 style entity bean.
