Release 10.1A: OpenEdge Development:
Progress 4GL Handbook

> ## Distributed applications

> Another limitation of your sample procedure is that is presumes that the client session running the interface has direct access to the database the application data is coming from. In a modern application, this is normally not the case. Whether you’re running your application on the Web with a browser-based UI, or simply providing global access to your database server from client machines running all over the country or all over the world, you won’t be able to provide all of your users with the same kind of direct database connection that you may have had with older host-based or client/server applications. Later chapters in this book introduce you to how to use the Progress 4GL to construct business logic procedures that can run close to your database server using the OpenEdge AppServer™ technology.
