### GemStone Object Application Server for VisualAge

GemStone is an award-winning object application server. It delivers application partitioning technology that enables corporations to adopt the emerging three-tier client/server architecture for building enterprise-wide business-critical solutions in VisualAge. This architecture makes it possible for client/server applications to scale while VisualAge Smalltalk allows developers to manage complex environments. This complete solution can then be integrated with corporate information resources, including relational databases and mainframes.

#### Centralizing your Business Objects

Business objects represent both data and rules critical to business operations across the enterprise. GemStone 5.0 provides a robust secure environment for sharing, managing, and reusing business objects. GemStone, in combination with VisualAge, allows for the simultaneous development of enterprise business objects and the applications that use them. As an object application server, GemStone supports the execution of business objects on high-end UNIX servers, improving network performance and reducing memory and processing requirements placed on clients.

GemStone provides a complete set of production services including the ability to support very large object collections and thousands of concurrent users. In addition, GemStone supplies transaction concurrency control, referential integrity, fault tolerance, 24x7 support, and security. The GemConnect product provides a high-performance object-to-relational connection.

#### Transparent Application Partitioning

GemBuilder for VisualAge includes development tools and middleware that allows a VisualAge Smalltalk application newly created or existing to take advantage of GemStone's scalable object server for enterprise-wide client/server deployment. The application developer and system designer can flexibly choose the machine on which GemStone object processing takes place. GemBuilder handles differences in operating systems and server architecture transparently to the application. For more information, please contact:
