Java With Hibernate And Jpa Practice Exam

The Java with Hibernate and JPA Certification Training exam is designed to provide participants with a comprehensive understanding of Java Persistence API (JPA) and Hibernate, and their integration with Java applications. JPA is a Java specification for accessing, persisting, and managing data between Java objects and relational databases, while Hibernate is a popular object-relational mapping (ORM) framework that implements the JPA specification. This exam covers essential concepts, techniques, and best practices for developing Java applications with Hibernate and JPA, including entity mapping, CRUD operations, querying, and transaction management. Participants will learn how to leverage Hibernate and JPA to build robust, scalable, and maintainable Java applications that interact with relational databases effectively.

Skills Required

• Proficiency in Java programming language, including object-oriented programming concepts and syntax.
• Familiarity with relational database concepts, SQL queries, and database management systems (DBMS).
• Understanding of web application development concepts, including HTTP, servlets, and web frameworks (e.g., Spring).
• Basic knowledge of ORM concepts and principles, such as object-relational mapping and entity relationships.
• Experience with software development tools, including IDEs (e.g., Eclipse, IntelliJ IDEA) and build tools (e.g., Maven, Gradle).

Who should take the exam?

• Java developers interested in enhancing their skills in database integration and ORM frameworks.
• Software engineers and architects looking to build scalable and maintainable Java applications with database connectivity.
• Database administrators seeking to understand how Hibernate and JPA can simplify database access and management in Java applications.
• Students and professionals aspiring to pursue careers in Java development and enterprise application development.
• Anyone interested in learning about Hibernate and JPA and their role in modern Java development projects.

Module 7: Java Persistence Query Language (JPQL)

• Introduction to Java Persistence Query Language (JPQL) and its similarities with SQL.
• Writing JPQL queries to interact with JPA entities and perform database operations.
• Leveraging JPQL features for entity mapping, joins, aggregates, and subqueries.

Module 8: Transaction Management with JPA

• Understanding transaction management concepts and principles in JPA.
• Implementing declarative and programmatic transaction management using JPA annotations and APIs.
• Handling transaction boundaries, isolation levels, and propagation behaviors in JPA applications.

Module 9: Entity Lifecycle and Persistence Context
