JPA as Tools for an Object Oriented Domain Modell using Hibernate as JPA Vendor. Presentation was held on customer site in Berlin and transmitted to the Lünen Office.
This document summarizes a presentation about reducing the need for travel. It discusses why meetings and travel are commonly used, the environmental impact of travel, and challenges organizations face in reducing travel. Key barriers to adopting travel reduction are reviewed, as are the benefits to organizations of using tools to replace in-person meetings with virtual communication. Steps for organizations to successfully adopt new tools and reduce their travel are provided.
EJB 3.2/JPA 2.1 Best Practices with Real-Life Examples - CON7535Ahmad Gohar
Session ID: CON7535
Session Title: EJB 3.2/JPA 2.1 Best Practice with life examples
Session Type: Conference Session
Session Abstract:
This session’s speaker, an architect, discusses lessons learned from using JPA and EJB to support a high-volume, high-performance applications. These best practices don't only involve JPA/EJB but also its integration with other Java EE 7 technologies. They also include coding best practices, testing and production practices. The presentation focuses primarily on some Key concepts such as persistence context, lazy loading, caching, flushing, dirty checking, transaction and connection demarcation. This is a fast-paced presentation with many code samples. Categories covered include configuration, JPA, concurrency, performance tuning, exception handling and many more.

The document discusses Java Persistence API (JPA), which is a specification that defines a Java API for object-relational mapping. It describes how JPA was created through the Java Community Process and references implementation. It also provides an overview of key JPA concepts including entities, the entity manager factory, entity managers, persistence contexts, and transaction types.
JPA and Hibernate are specifications and frameworks for object-relational mapping (ORM) in Java. JPA is a specification for ORM that is vendor-neutral, while Hibernate is an open-source implementation of JPA. Both use annotations to map Java classes to database tables. JPA queries use JPAQL while Hibernate supports both JPAQL and its own HQL. Additional features covered include relationships, inheritance mapping strategies, custom types, and querying.
The document discusses best practices for using the Java Persistence API (JPA). It covers:
- The entity manager and persistence context manage entities within a scope like a transaction.
- Entities transition between managed, detached, and removed states that impact database synchronization.
- Queries retrieve and manage entities from the persistence context and database.
- Transactions and locking strategies like optimistic and pessimistic concurrency control how changes are made.
- Extended and transaction scoped persistence contexts determine entity lifetime and caching.
- The second level cache can improve performance by caching entities across contexts.
The document discusses the Java Persistence API (JPA) and Hibernate framework. It provides an overview of JPA's main features, the five steps to implement JPA using Hibernate, and the components that make up Hibernate.

1. Hibernate ve JPA (Java Persistance API) JPA Nedir : Java EE 5 ile gelen standart persistance (verinin kalıcı hale gelmesi) API'sidir. Faydası : Daha önceden mevcut olan diğer veri kalıcılığı sağlayan kütüphanelerin ( Hibernate, Toplink, JDO gibi ) ortak bir tanım altında birleştirilmesi. Daha önce her kütüphane kendi API'sini veriyordu ve birinden diğerine geçiş zorlaşıyordu.
