Meeting....: Silicon Valley Java Users Group (SVJUG)

Time.......: February 12, 2003 (the second Wednesday
of each month)

Cost.......: Always FREE to all!

Topic......: Issues & Practices for Persistence
Architectures and Mapping

Speaker....: Donald Smith,Director of Technology,
Oracle9iAS

Description:
One of the major challenges faced by
enterprise Java developers is overcoming the
mismatch between objects and databases.
Storing objects in Java is more than simple
JDBC calls; a solid design incorporates a
persistence layer that separates the details
of the database from the business logic.
The persistence layer should address mapping
and run-time issues such as caching,
object identity, inheritance, legacy database
integration, querying, stored procedure use,
storing objects across multiple tables,
and transaction management. Additional
challenges arise through the use of multi-tier
architectures and application servers.
Moreover, customers face challenges with
disparate data sources and objects need
to be mapped and integrated with relational
data, mainframe data and ERP systems.

Enterprise JavaBeans developers face additional
challenges. Deciding what kind of EJB
architecture should be used for data-centric
enterprise applications, determining what
persistence strategies are best suited to EJB,
and understanding the problems specific to EJB
are among the key issues that must be
addressed.

The purpose of this talk is to outline the
persistence issues for Java objects and EJBs,
and to describe the various strategies employed
by persistence layers to solve these problems.
We will also discuss these challenges and
solutions in the context of various EJB
application architectures. It is assumed the
audience has some familiarity with Enterprise
JavaBeans. Basic relational database and object
modeling knowledge are also assumed.
