Trends in Object Persistence: Beyond EJB 3 and JDO 2
In this session, we identify current trends in Java object persistence
and extrapolate these trends to the bleeding edge of persistence technology and
beyond. Persistent data is a vital part of most enterprise
applications, and developers are increasingly turning to object persistence
solutions to simplify data access. We begin with a brief tour of
object persistence strategies, and we examine why products are converging on the
general model shared by JDO 2 and EJB 3. We then dissect this
shared model, focusing on how its transparency, runtime architecture, and query
facilities will evolve in the future. Convergence to a shared model
forces persistence vendors to find other differentiators, and the remainder of
the presentation delves into the advanced scalability and performance features
that are already emerging as a result. Scalability trends covered
include deployment flexibility, resource monitoring, and adaptive resource
management. In the realm of performance, we discuss fetch plans,
lock groups, declarative and adaptive tuning, and write-behind
caching. Throughout the presentation, we provide tips
on how to take advantage of the convergence in persistence models, and how to
design today's applications to align with current trends in object persistence,
rather than fight against them. We assume that session attendees
have experience with persistent data in one form or another.
Experience with object persistence frameworks is not necessary.
