Presentation: "Making Java Persistence Perform"
Track:
Performance in Modern Enterprise Systems
Time:
Tuesday 11:00 - 12:00
Location:
SAS Nortvegia
Abstract: The terms "performance" and "scalability" can be found in requirements documents, marketing glossies and white papers throughout the IT industry. But what do they mean, really? How are they related? And how can you write software that meets your performance and scalability needs? Patrick Linskey will discuss these questions and their answers in general terms, and then focus on the primary source of performance and scalability woes in the J2EE environment: the database. You will learn how to define your requirements and design a system that meets them, and you will gain an understanding of the tradeoffs implied by those needs.

Tutorial: "EJB 3 Persistence with OpenJPA"
Time:
Thursday 13:00 - 16:00
Location:
SAS Suecia
Abstract: The tutorial starts with a high level overview of EJB 3 persistence (better known as JPA) and the open source implementation OpenJPA. Thereafter, it examines the steps required to build a model and related service that uses JPA. Two deployment scenarios are considered: deployment as an EJB 3 stateless session bean and as part of a J2SE application. The last half of the tutorial examines JPA's and OpenJPA's support for relationships, detachment, attachment, and queries. Questions are welcomed throughout.
