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.

Architecture matters


You may be able to write a simple command-line application, a utility, or perhaps even a simple desktop application without formally defining your application architecture. But enterprise applications must start with architecture, as there are many moving parts, systems, and enterprise constraints. The job of an enterprise architect is to align business goals and objectives with an IT strategy. And this doesn't only mean implementing functional capabilities, business logic, or a user interface. Enterprise architects are also concerned with non-functional business goals, such as reducing business cost and minimizing risks. Besides implementing business capabilities, application architects are also responsible for implementing the governing policies defined by the enterprise architects.

For architecture, you can use transactions to minimize data loss or to ensure data integrity, or you can scale your application to accommodate higher number of users or business transactions...
