Basics of ORM, JPA, and Hibernate

ORM and JPA are widely used techniques in software development for handling relational databases. You don’t have to write complex SQL queries, instead you can work with objects.

• Object Relational Mapping (ORM) is a technique that allows you to fetch from and manipulate a database by using an object-oriented programming paradigm. ORM is really good for programmers because it relies on object-oriented concepts rather than database structures. It also makes development much faster and reduces the amount of source code. ORM is mostly independent of databases, and developers don't have to worry about vendor-specific SQL statements.
• Jakarta Persistent API (JPA, formerly Java Persistence API) provides object-relational mapping for Java developers. Th JPA entity is a Java class that presents the structure of a database table. The fields of an entity class present the columns of the database tables.
• Hibernate is the most popular Java-based JPA implementation...
