As data models get more complex it becomes harder for programmers to create applications to access that data. Enter Java Hibernate. Hibernate is a middle-tier developer framework for Object to Relational Mapping (ORM). A Hibernate tier is used as a go-between from the data tier to the client tier thus creating an automatic translation between the Object Oriented model and the required relational data model. This course will take the next step by showing you the higher functions of Hibernate like Mapping Inheritance, Annotations and Composite keys. You will then move on to Transactions and Querying, then Spring Hibernate Integration foundation and end with using Hibernate in Spring.

In this course, you will learn:

• What are the three Inheritance ORM strategies
• About Hibernate's implicit polymorphism strategy
• What is required to work with Hibernate's annotations
• What are the three object states: Transient, Persistent and Detached
• To describe the need for transaction control
• What are the three different ways of demarcating transactions
• The two ways of querying (Criteria and HQL)
• When to use the Jta Transaction Manager
• What are the two files used to define the Hibernate configuration

• Single Table Inheritance Pattern (i.e. Table Per Class Hierarchy)
• Class Table Inheritance Pattern (i.e. Table Per Subclass)
• Concrete Table Inheritance Pattern (i.e. Table Per Concrete Class)
• Configure Mappings
• The Concept of a Discriminator

• How Annotations Can Be Used with Hibernate
• Set Up and Obtain an Annotation-Capable Hibernate Session

• Use Annotations to Establish Persistence, Primary Keys, etc.
• Work with Annotations to Perform Mapping and Establish Relationships

• Transition from the Transient to Persistent State (i.e. How to Make Objects Persistent)
• Retrieve Hibernated Objects Using the Primary Key
• Retrieve Hibernated Objects Using Basic HQL
• Update Entities which are in the Persistent State

• Understand the Different Collection Types Supported
• Understand Programming Restrictions when Using Collections
• Understand Hibernate's Bags
• Introduce Dynamic Components

• The Basic HQL Syntax
• Work with the Results of a Query
• Handle Different Result Set Element Types (Unique, Array of Entity, Scalar)
• Use the Relationships Between Entities in your HQL
• Enable Pagination
• Concept of Named Queries
• Use Query By Example (QBE)

• The Spring DAO Infrastructure
• Transaction Demarcation within Spring
• Benefits of Using Declarative Transactions

• Overview of Spring Hibernate Support
• Session and Connection Management
• Create Hibernate DAOs
• Use the Hibernate Template Class
