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!
