![]() ![]() This video tutorial covers Hibernate API, JPA API, advanced mapping and configurations, and the criteria API. This online training course will teach you the basics of object-relational mapping and Hibernate.Īfter that, you learn more about basic mapping annotations, mapping composite and collection types, and entity associations. This one is another great course to learn the basics of Hibernate and JPA. ![]() You'll also learn the fundamentals and some of the advanced JPA features for object/relational mapping, querying, caching, performance, and concurrency.Ģ. Hibernate and Java Persistence API (JPA) Fundamentals Final (and applicable updates for Hibernate 5.0), and learn how to use Hibernate as a JPA provider. In this course, you will learn Hibernate 4.3.5. If you are a Java programmer that wants to learn fundamentals of Hibernate, JPA, and other advanced topics of Java Persistence with Hibernate, then this is the right course for you. 1. Java Persistence: Hibernate and JPA Fundamentals It will not only make your resume more attractive but also make you eligible for different jobs looking for Java developers with Spring and Hibernate experience. Given the importance of Hibernate and JPA, it's useful for Java developers to learn these APIs and frameworks. ![]() You can take these training courses from the comfort of your home and office to learn these important technologies at your own pace. In the past, I have shared online courses to learn Spring framework, and today, I'll share some of the useful Hibernate and JPA courses for Java developers. I have been sharing some useful resources for Java developers, and this is the second article in the series of learning essential frameworks for Java developers. 5 Online Courses to Learn Hibernate and JPA for Java Developers Hibernate is just one implementation of JPA, and if your company switches to another implementation, like TopLink, then you can easily switch to that if you use JPA APIs. On a similar note, you don't need to tightly couple your code to Hibernate you can use JPA (Java Persistence API), a standard API for the persistence layer of Java application. Keep in mind, if you have to do the same move, check out this link to learn about how I ported some of the SQL queries from Oracle to the SQL server. I had this experience in the past where we moved from Oracle to SQL Server and had to spend considerable time re-writing stuff that I didn't want. Had you opted for writing Data Access Object and SQL, you would have to re-write most of your SQL to port your application from one database to another. All you need to do is change the SQL dialect in Hibernate configuration file and you are done. The use of Hibernate also makes your application more portable for example, if, tomorrow, your company decides to switch to Oracle from Microsoft SQL Server, or MySQL to PostgreSQL, you don't need to re-write any SQL query. If you only use Hibernate to touch your data, then it will always be up-to-date. You don't need to worry about data getting scale or the cache growing bigger and bigger Hibernate can manage both cache eviction and how to keep it up-to-date. first level, second level, and query cache, which can hold frequently-used data to improve the performance of your Java application. Hibernate maintains a couple of caches, e.g. Keep in mind, this is just one benefit of using Hibernate, another one is that it provides inbuilt caching. Instead of loading and saving data to/from the database and then populating objects, Hibernate gives you a readymade object and takes care of updating data when the state of object changes. It will allow you to deal with just objects while it loads, saves, and updates data in the background. For example, instead of writing classes with SQL to load, save, and update data using the DAO design pattern, you can simply use the Hibernate framework in your project. It's an ORM tool that allows you to deal with only objects while Hibernate takes care of your data on your behalf. Hibernate is one of the essential frameworks for Java, Java EE, and JEE programmers, especially if you are working on the server side of a Java web development project.
