Release 10.1A: OpenEdge Deployment:
WebClient Applications

Accessing databases only through an AppServer

Databases must be accessed through an AppServer. They cannot be accessed directly by the client. That is, all database data presented by the application to the end user must originate on an AppServer, and all database data entered by the end user must be sent to an AppServer for evaluation and storage. To pass relational-database data (such as rows of data) between AppServer and client, you can use temp-table parameters in remote procedures. For more information on temp-table parameters and remote procedures, see OpenEdge Development: Progress 4GL Handbook . In addition, the SmartObjects provided with OpenEdge for packaging business logic on an AppServer also provide access to any databases or DataServers the application requires.
