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, which is more natural for Java developers. In this way, ORM and JPA can speed up your development process by reducing the time you spend writing and debugging SQL code. Many JPA implementations can also generate a database schema automatically based on your Java entity classes. In brief:
- 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.
