GemStone/J Overview
What is GemStone/J
 An integrated Java Application Server
 Designed for 3 tier transactional Java
applications built with components
 Java VM and runtime with significant value
added
 Implicit Java object persistence



For application control and meta-data
For shared data caches
For extending relational and mainframe data
 Integrates middleware and component
technologies such as J2EE, EJB and CORBA
 Supports development and deployment of
large, complex business applications in Java

Architectural Issues in the near
future
 Architectural Patterns that
 realize scalability
 preserve cache coherency
 preserve component & object models
 incorporate Web, CORBA, RMI & JMS
mechanisms
 Component to object mapping or EJB to RDB
