Popis kurzu Building Database Driven Applications with JPA SL-370-EE6

The Building Database-Driven Applications with Java Persistence API course examines the ins-and-outs of building database applications. Expert Oracle instructors will teach you how to use the standard Java object-relational-mapping technology, Java Persistence API.Learn To:Implement business-tier functionality using Java Persistence API technology.Describe best practices and other advanced issues in business component development with Java Persistence API technology.Assemble and deploy Java Persistence API technology business-tier components on an application server, as well as in stand-alone applications.Create and use Query objects using the Java Persistence Query Language.Key Concepts Covered in this CourseThis course will teach you the key concepts found in the Java Persistence API. You'll learn how to create robust entity models, along with static and dynamic queries using Java Persistence API Query Language. You'll also explore how to create type-safe queries with the Java Persistence API Criteria API. Java Persistence APIEnrolling in this course will also teach you about the Java Persistence API within a stand-alone Java Standard Edition application. Learn within the context of a web-based Java Enterprise Edition application, including using Java Persistence API with the Enterprise JavaBeans technology.Students Who May Benefit from this Course:Java Developers building components that take advantage of Java Persistence API technology or are migrating from the structured development of traditional JDBC-driven database access.Java Developers interested in preparing for the Sun Certified Java Persistence Developer examination.This course covers both new features found in the Java Persistence API 2.0, as well as the features found in Java Persistence API 1.0.

Audience:

  • Application Developers

  • Display experience with the Java programming language

Topics:

Overview of the Java Persistence API

  • Describe the basics of Object Relational Mapping (ORM)
  • Define the key concepts of the Java Persistence API (entity, entity manager, and persistence unit)

Introducing the Auction Application

  • Describe the implementation model for the auction system

Java Persistence API Entities

  • Describe the difference between objects and entities
  • Describe the difference between persistent fields and properties
  • Identify and use common Java Persistence API annotations, such as @Entity, @Id, @Table, and @Column

Understanding the Entity Manager

  • Describe the relationship between an entity manager, a persistence context, and a persistence unit
  • Describe the difference between a container-managed entity manager and an application-managed entity manager
  • Describe the entity life cycle

Modeling Entity Relationships

  • Examining object/relational inheritance hierarchy mapping strategies
  • Inherit from an entity class
  • Inherit using a mapped superclass
  • Inherit from a non-entity class
  • Examine inheritance mapping strategies
  • Use an embeddable class

Persisting Enums and Collections

Implementing Transactions and Locking

  • Describe the transaction demarcation management
  • Implement container-managed transactions (CMT)
  • Interact programmatically with an ongoing CMT transaction
  • Implement bean-managed transactions (BMT)
  • Apply transactions to the Java Persistence API

Advanced Java Persistence API Concepts

  • Specify composite primary keys
