Map and query your entities from relational databases using JPA and Panache ORM

What you'll learn
Understand the persistence ecosystem and how Quarkus supports it
Bootstrap three data-centric applications with Quarkus
Develop, configure and test each application separately using JDBC, JPA, Panache ORM, JUnit and RestAssured
Persist objects into MySQL, MariaDB, H2 and PostgresSQL databases
Use JPA to map persistent objects (columns, tables, inheritance, relationships)
Use JPQL and Simplified Panache QL to query persistent objects
Use JAX-RS and JSON-B to expose data through REST endpoints
Use Qute templates to visualise data in HTML
Beautify the Qute templates with Twitter Bootstrap
Use Docker through TestContainers and DevServices to test the application
Build and execute the application using several Quarkus profiles

Requirements
A recent Windows / Mac / Linux machine
Knowledge of the Java language and the Java ecosystem (Maven, JUnit)
Basic knowledge of Quarkus
Basic knowledge of relational databases (SQL)
Basic knowledge of RESTful Web Services
Basic knowledge of HTML and CSS
Basic knowledge of Docker

Description
This course is for Quarkus developers who want to discover how Quarkus handles relational databases. It's a mixture of slides and code so you can "Understand and Practice" at the same time. This way, you learn the theory, and then put it into practice by developing an application step by step.In this course you will develop a Quarkus applications maps and queries different kind of persistent objects to several relational databases. After introducing JDBC, JPA and Panache ORM, you will make sure your development environment is set up, and you will go from bootstrapping three Quarkus applications, developing and refactoring a rich business model, map and query these objects to a Postgres database. The different steps you'll go through are:Understand JDBC, JPA and Panache ORMUnderstand SQL, JPQL and Simplified Panache JPQLUnderstand the differences between Panache Active Record and Panache RepositoriesCheck your development environmentBootstrap three Quarkus applications:o POJOs and JDBC with MySQLo JPA Entities with MariaDBo Panache ORM Entities with PostgresSQLTest and refactor these applications so they have dependencies between themMap persistent objects to a relational database (with annotations and XML)Map inheritance and relationshipsQuery persistent objects using JPQL and Simplified Panache QLExpose data in JSON using REST endpoint with JAX-RS and JSON-BHandle transactionsVisualise data in HTML using Qute templates and Twitter BootstrapUse Quarkus profiles to switch between databaseExecute the application in dev/test/production mode thanks to DevServices and DockerAt the end of the course you'll get a good understanding on how to develop a data centric application with Quarkus. You will be able to bootstrap, develop, package and execute an application that accesses a relational database, but most important, take Quarkus to your next project.Good luck for the course, and please reach out if you need any help or if you have any request: I'm here to help!

Who this course is for:
Java developers who know Quarkus,Quarkus developers curious about relational databases,Back-end Java developers willing to access data in an object way,Spring Boot or Micronaut developers wanting to compare their toolkit with Quarkus
