Course Outline

1. Introduction to Hibernate
	Topics What is Hibernate? Relational Database Technology Accessing Relational Databases from Java Domain Models Comparing Object and Relational Models Identity Modeling Granularity of Objects and Tables Association Modeling Navigation Inheritance What is Object/Relational Mapping? Advantages of using an ORM Tool Architecture of Hibernate Hibernate API Extension Interfaces Hibernate Configuration Hibernate Mappings Hibernate Properties Hibernate XML Configuration Files Non-Managed and Managed Environments Configuration in a Non-Managed Environment Configuration in a Managed Environment Binding SessionFactory to JNDI A Simple Example Alternatives to Hibernate EJB Entity Beans Hand-Coded Persistence Using JDBC Object-Oriented Databases Other ORM Tools

2. Basic Mappings
	Topics Creating the Domain Model Domain Model Domain Objects Hibernate Requirements Object Identity Primary Keys Natural Keys vs. Surrogate Keys Identifier Property Identifier Generators Hibernate Managed Identifiers Mapping Metadata Mapping Properties Property Access Strategies Derived Properties Preventing Insert/Update Using Database Schemas Quoted SQL Identifiers Specifying Java Packages Entity and Value Types Components Bi-Directional Components Other Component Details Association Mappings Many-to-One Association One-to-Many Association Inheritance Mapping Strategies Table per Concrete Class Table per Subclass Table per Class Hierarchy

3. Manipulating Persistent Objects
	Topics Object States Transient Objects Persistent Objects Detached Objects Object Identity Persisting a Transient Object Retrieving and Updating a Persistent Object Deleting a Persistent Object Updating a Detached Object Transitive Persistence Using save-update Differentiating Between Transient and Detached Objects HQL Queries Parameter Binding Pagination Named Queries Polymorphic Queries Restriction String Comparison Logical Operators Ordering the Results Join Queries Implicit Joins Where Clause Joins Criteria Queries Polymorphic Criteria Queries Restricting Criteria Queries Comparing Strings in Criteria Queries Using Logical Operators in Criteria Queries Ordering Results in Criteria Queries Using Joins in Criteria Queries Using Dot Notation to Get Component Properties

4. Advanced Mappings
	Topics One-to-One Associations Many-to-Many Associations Polymorphic Associations Entity vs. Value Types Built-in Mapping Types Using Mapping Types Custom Mapping Types Collections of Value Types Set of Value Types Bag of Value Types List of Value Types Map of Value Types Collections of Components Sorting Collections

5. Transactions, Concurrency and Performance
	Topics Database Transactions JDBC and JTA Transactions Hibernate Transactions Flushing the Hibernate Session Isolation Issues Isolation Levels Configuring the Isolation Level Pessimistic Locking Application Transactions Application Transaction Isolation Managed Versioning Using Existing Properties to Implement Optimistic Locking Caching Hibernate Cache Architecture The First-Level Cache The Second-Level Cache Cache Concurrency Strategies Enabling the Second-Level Cache Cache Regions Specifying a Cache Provider Support for Cache Providers Explicitly Evicting Objects From the Second-Level Cache Fetching Strategies Fetching Strategies in Mappings – Single Point Associations Fetching Strategies in Mappings –Collections Fetching Strategies in Mappings –Batches Explicit Initialization of Lazily Loaded Objects Fetching Strategies in HQL Queries Fetching Strategies in Criteria Queries The N+1 Selects Issue Report Queries - Projections Report Queries – Projections Report Queries – Aggregation Report Queries – Grouping

6. Tools and Design Techniques
	Topics Generating the Database Schema Generating the Domain Model Generating the Database Schema Using Middlegen Using XDoclet The Open Session in View Pattern Using a Natural Key Using a Composite Key Dealing with Database Triggers
