Overview of this book

Hibernate has been so successful since its inception that it even influenced the Java Enterprise Edition specification in that the Java Persistence API was dramatically changed to do it the Hibernate way. Hibernate is the tool that solves the complex problem of Object Relational Mapping. It can be used in both Java Enterprise applications as well as .Net applications. Additionally, it can be used for both SQL and NoSQL data stores. Some developers learn the basics of Hibernate and hit the ground quickly. But when demands go beyond the basics, they take a reactive approach instead of learning the fundamentals and core concepts. However, the secret to success for any good developer is knowing and understanding the tools at your disposal. It’s time to learn about your tool to use it better This book first explores the internals of Hibernate by discussing what occurs inside a Hibernate session and how Entities are managed. Then, we cover core topics such as mapping, querying, caching, and we demonstrate how to use a wide range of very useful annotations. Additionally, you will learn how to create event listeners or interceptors utilizing the improved architecture in the latest version of Hibernate.

The Cloud strategy


Cloud deployment is more popular than ever. Nowadays, most enterprise applications are designed to run either on-premise or in the cloud. You can create an application that offers the same services to different clients, while isolating the client data from each other. There are several motivational factors behind this strategy and one of those is to save licensing costs. This is common when creating Software-as-a-Service (SaaS).

Licensing

In a cloud architecture, you only use and pay for the things that you need. You can create an application that only requires a database, and you don't need content management, image processing, message queuing, or other services. Even if you deploy on-premise, some vendors offer licensing models to enable features only if you pay for them.

Furthermore, some application servers and database vendors charge per instance or even per schema. You can use various techniques to reduce your cost so you don't have to pay the additional fee, one is...
