Core Components of Hibernate framework

Core Components of Hibernate

✔️ Connection Management ✔️ Transaction management ✔️ Object relational mapping Hibernate Configuration file: ✔️ Hibernate requires some the mapping information that defines the Java classes that relates to the database tables. ✔️ A set of configuration settings related to database and other related parameters are required and stored in a standard Java properties file called hibernate.properties, or as an XML file named hibernate.cfg.xml. Hibernate Mapping file: ✔️ Mapping and Configuration always co-exist in hibernate as every hibernate program need these two xml files. ✔️ It is the core part of hibernate. ✔️ ORM tool requires mapping which puts an object’s properties into the columns of a table. ✔️ Though, Mapping can be done in the form of an XML or in the form of the annotations

Annotation

✔️ The hibernate application can be created with annotation. 

✔️ There are many annotations that can be used to create hibernate application such as @Entity, @Id, @Table etc. The core advantage of using hibernate annotation is that you don't need to create mapping (hbm) file. 

✔️ Mapping file instructs Hibernate how to map the defined class or classes to the database tables.
