In the past, web and enterprise application architectures only use JBoss extensively to service compute-, display- and data- intensive operations. But Web 2.0 and other advanced applications require much higher volumes of transactional data and have scaling requirements that are indeterminate. This paper suggests a rebalancing of responsibilities between JBoss and Postgres Plus that improve database performance and consistency, while delivering more resources to the application's computational and UI operations. This paper will help you understand the prospects that Postgres Plus RDBMS from EnterpriseDB and the JBoss Application Server from Red Hat can provide when used in combination.
