To implement this pattern using the best practices of Java EE 8, we will use a relational database and implement the data read and write using a JPA specification. In this example, we will have one table named employee, which contains the employee data. We will also create a class called EmployeeDao which will have four methods –save(employee), findByName(name), findAll(), and delete(employee). The save method will receive one employee and save them on the database, findByNamewill receive the name as a parameter and will find the employee by name on the database, anddeletewill receive an employee and delete them from the database. Also, we are going to create a transfer object calledEmployee, a class that is a JPA entity and has the mapping to a database table.

Overview of this book
Patterns are essential design tools for Java developers. Java EE Design Patterns and Best Practices helps developers attain better code quality and progress to higher levels of architectural creativity by examining the purpose of each available pattern and demonstrating its implementation with various code examples. This book will take you through a number of patterns and their Java EE-specific implementations.
In the beginning, you will learn the foundation for, and importance of, design patterns in Java EE, and then will move on to implement various patterns on the presentation tier, business tier, and integration tier. Further, you will explore the patterns involved in Aspect-Oriented Programming (AOP) and take a closer look at reactive patterns. Moving on, you will be introduced to modern architectural patterns involved in composing microservices and cloud-native applications. You will get acquainted with security patterns and operational patterns involved in scaling and monitoring, along with some patterns involved in deployment.
By the end of the book, you will be able to efficiently address common problems faced when developing applications and will be comfortable working on scalable and maintainable projects of any size.
