Difference between JDBC and Hibernate ?

  • Hibernate is ORM wich maps POJO using xml file to access and create data form hatro database. but in jdbc developers has to write code to map object model data to RDBMS and it access.
  • JDBC using SQL to access database developer has to effective way to access the database. but hibernate provides HQL which powerful and includes all feature of SQL and supports ploymorphic query.
  • Hibernate data transaction is fast due to work is perform due container mean its xml file mostly but JDBC has slow transaction.
