It is upon the developer to write transaction management code using commit and rollback methods. Transaction Management: JDBC doesn't support implicit transaction management.A developer has to know the database-specific codes. This helps in reducing the burden on developers for writing database independent queries. HQL (Hibernate Query Language): Hibernate provides HQL which is closer to Java and is object-oriented in nature.Clean Readable Code: Using hibernate, helps in eliminating a lot of JDBC API-based boiler-plate codes, thereby making the code look cleaner and readable.The advantages of Hibernate over JDBC are listed below: What are the advantages of Hibernate over JDBC? This article would cover basic, intermediate, and advanced questions.Ģ. Top we will walk you through the top questions to get you ready for a Hibernate interview. All these helps developers to save a lot of time involved in development. Along with abstraction, the queries can be executed in a very efficient manner. The developer need not know the underlying complications involved. It does so by mapping the POJO objects with the database tables efficiently and most importantly in an abstract manner. The aim of hibernate framework is to free the developer from the common data persistence-related complex configurations and tasks. Hibernate is a Java-based persistence framework and an object-relational mapping (ORM) framework that basically allows a developer to map POJO - plain old Java objects - to relational database tables. Can you tell something about Named SQL Query Can you tell something about Table Per Class Strategy. What are the concurrency strategies available in hibernate? How to solve N+1 SELECT problem in Hibernate? Can you tell something about the N+1 SELECT problem in Hibernate? What are the states of a persistent entity? What happens when the no-args constructor is absent in the Entity bean?
