⭐ Configuration:
π The main use of Configuration in Hibernate is to provide all the necessary information about your database
π It specifies the details of your database connection, such as the URL, username, password, and driver class in XML file. This allows Hibernate to establish a connection to your database.
π Once we done configuration we can use it to create a SessionFactory.
Example: Configuration config=new Configuration( );
⭐ SessionFactory:
πThe SessionFactory is like a factory it produces Session objects
π SessionFactory is a heavyweight object that's created once, usually during the startup of your application
π When your application needs to interact with the database, it requests a Session from the SessionFactory. The Session acts as a gateway to the database, allowing you to perform database operations such as saving, updating, or querying data.
Example: SessionFactiory sf=config.buildSessionFactory( );
⭐ Session:
π In Hibernate, a Session is a crucial component that represents a single unit of work with the database.
πThe Session as a bridge between your Java application and the database. It allows you to interact with the database by performing various operations like saving, updating, deleting, or querying data.
πHibernate caches data within a Session to optimize performance. This means that if you retrieve the same data multiple times within a single Session
Example: Session session=sf.openSession;
➡ JSON, XML, and CSV are commonly used for data interchange! in RESTAPI's ok but what is data interchange!?? ⤵ ➡ data interchange format like a language that computers use to talk to each other. Just as people use different languages to communicate, like English, Spanish, or Chinese, computers use specific formats to exchange information. These formats make sure that data is structured in a way that both computers can understand, whether they're sharing data over the internet, saving it to a file, or passing it between different parts of a program. JSON(JavaScript Object Notation) : it used for representing structured data in RESTful APIs, particularly in Spring Web applications. Spring provides excellent support for JSON processing through libraries like Jackson, ➡ It is like writing down information in a way that's easy for both humans and computers to understand. It's a simple and readable format that's often used for transmitting data between a web server ...
