![]() ![]() It is an Object-Oriented Query Language and is independent of the database. HQL is the acronym of Hibernate Query Language. Hibernate supports a variety of technologies, like: Exception handling is not mandatory in the case of Hibernate.This Java framework also has an Auto Primary Key Generation support.Hibernate uses Hibernate Query Language(HQL) which makes it database-independent.It reduces the length of code with increased readability by overcoming the boilerplate problem.It overcomes the exception-handling part which is mandatory while working on JDBC.Hibernate strengthens the object level relationship.Code portability is not an option while working on JDBC.Changing of the databases cost a lot working on JDBC, hibernate overcomes this problem with flying colors.It overcomes the database dependency faced in the JDBC.Hibernate overcomes the shortcomings of other technologies like JDBC. ![]() It internally uses the Java API to interact with the databases. An ORM tool helps in simplifying data creation, manipulation, and access. It is basically a technique that maps the object that is stored in the database. Hibernate wraps JDBC exceptions and throw JDBCException or HibernateException which are the unchecked exceptions, so you don’t have to write code to handle it has built-in transaction management which helps in removing the usage of try-catch blocks. JDBC throws SQLException that is a checked exception, so you have to write a lot of try-catch block code.Hibernate implicitly provides transaction management whereas, in JDBC API, you need to write code for transaction management using commit and rollback.But for JDBC, you need to write native SQL queries. HQL (Hibernate Query Language) is more object-oriented and close to Java.These features are actually not present in JDBC. This Java framework supports inheritance, associations, and collections.Hibernate eliminates a lot of boiler-plate code that comes with JDBC API, the code looks cleaner and readable.Major advantages of using Hibernate over JDBC are: It provides query statistics and database status.Provides facilities to automatically create a table.Helps in generating database independant queries.What are the major advantages of Hibernate Framework? It is a lightweight tool and most importantly open-sourced which gives it an edge over other frameworks. Hibernate develops persistence logic, which stores and processes the data for longer use. ![]() The implementations include tasks like writing a query for CRUDoperations or establishing a connection with the databases, etc. It is referred as a framework which comes with an abstraction layer and also handles the implementations internally. Hibernate also provides a reference implementation of Java API. It is an Object-relational mapping (ORM) tool. Hibernate is one of the most popular Java frameworks that simplify the development of Java application to interact with the database. Let’s begin! Hibernate Interview Questions for beginners Q1.
