Why we are using hibernate and how does it help in the programming?

Answer 1

Hibernate is the ORM (Object Relational Mapping).

->Hibernate will act like bridge between Application and Database.
->Hibernate use to access Database properties like (Tables, Views, Stored Procedures)

Hibernate Example:

Create Class:
public class Employee {
   public virtual int Emp_Id{ get; set;}
  public virtual string Emp_Name{get;set;}
}

-->COLUMN field for specify Table column field
-->Name field for specify Class Variable

<hibernate-mapping>
   <class name="Employee" table="EMPLOYEE">
      <meta attribute="class-description">
         This class contains the employee detail. 
      </meta>
      <id name="Emp_Id" type="int" column="id">
         <generator class="native"/>
      </id>
      <property name="Emp_Name" column="name" type="string"/>
   </class>
</hibernate-mapping>
