#10 JPA & POSTGRESQL | JAVA PERSISTENCE API JPA | Tutorial | Java | JakartaEE | Docker | PostgreSQL

✅ JPA & PostgreSQL

Java Persistence (JPA; formerly Java Persistence API) is a Jakarta EE application programming interface specification that describes the management of relational data in enterprise Java applications.

PostgreSQL, also known as Postgres, is a free and open-source relational database management system emphasizing extensibility and SQL compliance. It was originally named POSTGRES, referring to its origins as a successor to the Ingres database developed at the University of California, Berkeley.

Docker is a set of the platform as service products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries, and configuration files; they can communicate with each other through well-defined channels.

pgAdmin 4 is a complete rewrite of pgAdmin, built using Python and Javascript/jQuery. A desktop runtime written in C++ with Qt allows it to run standalone for individual users, or the web application code may be deployed directly on a web server for use by one or more users through their web browser. The software has the look and feels of a desktop application whatever the runtime environment is, and vastly improves on pgAdmin III with updated user interface elements, multi-user/web deployment options, dashboards and more modern design.


This tutorial will be the last of the JPA Tutorials.
In this video, we are going to learn to configure and use the database PostgreSQL with JPA.
To use PostgreSQL and JPA I need to download and install PostgreSQL first. To do that I’m going to use Docker.

We’re going to use the EntityManager to create a CriteriaBuilder object.
After that, using the CriteriaBuilder we're going to create the CriteriaQuery. The CriteriaQuery is used to create a query object.
