Hibernate framework Architecture:
It includes many objects such as
✔️ persistent object
✔️ session factory,
✔️ transaction factory,
✔️ connection factory,
✔️ session,
✔️ transaction etc.
The Hibernate architecture is categorized in four layers
✔️Java application layer
✔️Hibernate framework layer
✔️Backend API layer
✔️Database layer

Advantages
✔️ Open Source and Lightweight
✔️ Fast Performance
✔️ Database Independent Query
✔️ Automatic Table Creation
✔️ Simplifies Complex Join
✔️ Provides Query Statistics and Database Status
Disadvantages
✔️ It can’t be learnt easily.
✔️ The debugging due to xml files and performance tuning becomes difficult at times.
✔️ Hibernate is a bit slower than pure JDBC as it is generating lots of SQL ✔️ statements in runtime.
✔️ It advisable to use pure JDBC for batch processing.

✔️ Developers use JDBC for communicating with the DB and the java app.
✔️ JDBC programming needs to create SQL statement, execute the statement and then process the results, Also the runtime exceptions are needed to be handled.
✔️ To effectively solve above issue, ORM tool was developed.
✔️ The ORM tool generates the SQL statements, executes the SQL statement and finally processes the result.
✔️ It also handles the exceptions occurred in the program.
Features of Hibernate
✔️ Object/Relational Mapping
✔️ JPA Provider
✔️ Idiomatic (Natural) persistence
✔️ High Performance
✔️ Scalability
✔️ Reliable
✔️ Extensibility

➡️ Hibernate is the ORM tool to transfer the data between a java (object) app and a database (Relational) in the form of the objects.
➡️ It is an open source, light weight tool given by Gavin King.
➡️ It is a non-invasive (don’t force) framework, it doesn’t force the developers to extend/implement any class/interface, there are only POJO classes so its light weight.
➡️ It can run with-in or with-out server, it will suitable for all types of java apps (desktop or servers)
➡️ It is purely for persistence (to store/retrieve data from DB).
