Course Number: JAVA.021 Duration: 3 days (full-day sessions) OR weekend/evening sessions Training Overview: Hibernate is an open source object/relational (OR) persistence and query service for Java. Hibernate lets you develop persistent classes following common Java idioms - including association, inheritance, polymorphism, composition, and the Java collections framework. The Hibernate Query Language, designed as a minimal object-oriented extension to SQL, provides an elegant bridge between the object and relational worlds. Hibernate also allows you to express queries using native SQL or Java-based Criteria and Example queries. This course covers everything you need to know to begin working with Hibernate in a very short time. It covers all the important concepts necessary to access and update data stored in relational databases. It includes an extensive series of labs to exercise all major capabilities. Location and Pricing: Most of our courses are conducted online OR at our training facility and are customized to meet our students needs. We also provide customized onsite training at our clients' locations. Pricing for an online course depends on if its a weekend/evening course or a full day course. The weekend/evening courses are most cost-effective as they are spread over a period of weeks giving you ample time to complete the hands-on exercises. To receive a customized proposal that will fit your schedule and price quote, please contact us  Training Prerequisites: Beginning Java Application Development or equivalent experience. Training format: This class is 60% lecture, 40% hands-on, with one-on-one dedicated time-slots with the instructor. Training Materials: All students receive a copy of related courseware / material. Software Needed on Each Student PC: Java SE SDK The Hibernate persistence engine Ant Relational Database (RDBMS) - if you don't have one, HoneZone instructor will provide one. Java IDE of your choice (We will advise on specific versions of the software required based on your standard development and production environments.) Training Objectives: Understand the benefits of Hibernate Understand the Hibernate architecture Create Hibernate based applications Understand and use Hibernate mapping to map persistent objects to the database Understand and work with collections & associations Value and Entity Types Bidrectional and unidirectional 1-1, 1-N, N-N Use Hibernate's versioning support Map inheritance hierarchies using Hibernate Work with Hibernate queries, HQL, and Criteria Performance tune your Hibernate applications Understand Hibernate transaction support Understand the relationship between Hibernate and Java Persistence / EJB 3 Use the new Hibernate annotations to do OR mapping Training Outline: Introduction to Hibernate Issues with Persistence layers and Object-Relational Mapping (ORM) Hibernate Overview and Benefits Hibernate architecture overview POJO (Plain Old Java Object) Based Mapping Getting started with Hibernate quickly Overview of the Hibernate distribution Configuring Hibernate hibernate.cfg.xml file SessionFactory configuration Connection properties, Database dialect Configuration class, Session Interface "Hello World" Program for Hibernate Mapping a Class Persistent Entity Class, Hibernate Mapping File, Mapping the Entity Class Primary keys: Id property, Generated Id Hibernate Type System Working with sessions and Persistent Objects Logging - log4j Overview and configuration for Hibernate Querying Inserting and Updating Entities HQL - Hibernate Query Language Overview The Query Interface Creating and working with queries Named Queries, Projection Queries, Aggregate Queries The Persistence Lifecycle Transaction Overview and Transactions in Hibernate Hibernate Transaction API (in Managed and Non-managed Environments) The lifecycle of managed objects Persistent, transient, and detached objects The Persistence (Session) Context (Lifespan, Relation to Managed Objects, Propagation) Contextual Sessions Synchronization to the Database The Session as cache Optimistic Locking / Versioning Detached Objects and Optimistic Locking Versioning overview and Using Versioning Locking Objects Relationships Object Relationship Overview Mapping Collections of Value Objects Entity Relationships: 1-N, N-1, N-N, 1-1 Mapping Entity Relationships Uni and Bi-directional Relationships The Relationship "inverse" Cascading Over Relationships Queries Across Relationships (Lazy and Eager) Inheritance Mapping Entity Inheritance with Hibernate Table-per-class mapping Table per Subclass mapping Table per Concrete Class mapping Additional Querying Capabilities Projection Queries, Aggregate queries Bulk updates and deletes Native SQL Queries Query Filters The Criteria API Overview of the Criteria API Working Querying with the Criteria API Query by Example Hibernate and Java Persistence / EJB 3 Overview of Java Persistence / EJB 3 Relationship between Java Persistence and Hibernate Overview of Annotations Mapping Entities with Hibernate Annotations The EntityManager, Persistence Context and Persistence Unit Working with Transactions - EntityTransaction, Managed, and Unmanaged Environments Inserts and Updates JPQL - Java Persistence Query Language Versioning Relationships Advanced Topics Components and Multi-Table Mapping equals() and hashCode() Caching and Efficiency Design Considerations Final Review
