1. What is Hibernate Simply said hibernate is a ORM framework, where ORM stands for Object (Java) - Relational (DB) mapping, Hibernate is developed based on JDBC api, which has greatly reduced the code work when dealing with Databse. 2. Environment set up and Code example. Four steps ar...
One JPA ORM may be a better fit than another, depending on exactly what you are trying to do or on personal preference. The bottom line: You have lots of options for data persistence within Java applications. Several frameworks exist within the JPA category, and there are options beyond ...

Now that we know that using an ORM is not essentially a bad idea but can actually be a very productive way of writing code that interacts with the database, let's turn our attention back to NHibernate.NHibernate stands on three important building blocks. To understand these building blocks...
JDBC stands for Java Database Connectivity. It used concepts like Statement, PreparedStatement, and ResultSet. In the example below, the query used isUpdate todo set user=?, desc=?, target_date=?, is_done=? where id=? The values needed to execute the query are set into the query using...
The JPA setParameter Query method is very useful for basic entity properties that can be mapped using the default Hibernate ORM types.However, for custom column types, like JSON, you should use the Hibernate-specific org.hibernate.query.Query interface and call the setParameter method that allows ...
own code. I have changed the behaviors of some classes too. So I am not claiming that my implementation is an exact copy of the Spring framework for Java. I have just implemented theSpring.Orm.dllas an integration between NHibernate and Spring.Net, like thespring.orm.jarin the Java ...
[5]. Since session factories serve as persistence configurations in Hibernate, we remove the need for a shared, global SessionFactory by allowing each persistent module to have its own individually configured, module-specific SessionFactory (see Figure 1, SFAstands for the SessionFactory of Module ...
