San Francisco, CA. October 23, 2003 -
THOUGHT Inc.®,
The Dynamic O/R Mapping™ Company, shows how to successfully
use Enterprise JavaBeans with CocoBase® Enterprise O/R - the
market leader and award winning Dynamic Object to Relational Mapping™
tool - in their corporate applications that meet performance, scaling
and other important requirements. As J2EE and the EJB specifications
have evolved, certain design assumptions have become accepted as
the truth, although they are often incorrect or not the optimal
design choice. In response to this, the technical team at Thought
Inc. put together a technical paper clarifying and responding to
a number of misconceptions regarding developing with EJBs. The goal
is to assist developers to successfully use J2EE and EJBs in conjunction
with CocoBase® to construct high performance and scalable J2EE
applications.
Developers can
use this technical paper to further clarify when using an EJB is
the optimum approach. It provides guidance as to how to accomplish
common design goals using the most appropriate J2EE and EJB technology.
The paper covers topics such as performance, listing behavior /
cursor control, entity relationships, controls for cascade operations,
transparent persistence, scalability, writing consistent and high
quality EJBs, transaction management, read only systems, etc. Developers
learn how to benefit from the years of experience and evolution
contained in CocoBase® plus how it greatly simplifies the writing
and using of EJBs.
For example,
one major problem with Entity Beans experienced by enterprises is
their performance. The CocoBase® architecture provides a number
of solutions for the developer to overcome the performance challenge.
One solution is that CocoBase® supports 'dependent objects'
for entity beans which improves overall resource and system requirements
when compared to a fine-grained entity bean approach. For a sample
scenario, we can assume a Customer Entity Bean, which has a relationship
to Order objects with 1-m multiplicity. With CocoBase®, that
relationship can be defined as a Standard Link (STD_LINK) type and
the dependent objects are a serialized collection of value objects
sharing the same ejbLoad, ejbStore, related transaction and the
same JDBC connection pool. This can reduce overhead significantly
for entity beans by reducing the amount of SQL, the number of JDBC
connections and transaction contexts, the number of Entity Beans
that must be pooled and managed by the server, as well as the amount
of network traffic necessary to access a more complex model of data.
This one solution
alone can be more than sufficient to provide acceptable performance
levels for a corporate application. When added to other key technologies
such as fault tolerant distributed caching, optimistic locking,
optimized field updates, mapping objects that span tables, etc.,
these techniques in conjunction with CocoBase® become an indispensable
toolset and guideline document for developers.

About CocoBaseâ Enterprise O/R
CocoBase®
Enterprise O/R, Optimized for J2EE and J2SE Customer Success, solves
the Object to Relational impedance mismatch. The mature technological
leader, available since early 1997 and in its' fourth major release,
virtually eliminates the need to hand-code database access for EJB
and Java Applications. This can directly decrease up to 85% of the
cost of database access development for enterprise customers faced
with deploying fine-grained / coarse grained relationships in company
applications.
