Introducing SQL Anywhere Studio
  The Architecture of Database Applications
    Using multiple databases

Accessing data in other databases

You can access databases on multiple database servers, or even on the same server, using the Adaptive Server Anywhere Remote Data Access features. The application is still connected to a single database as in the architecture diagrams above, but by defining remote servers, you can use proxy tables that exist on the remote database as if they were in the database to which you are connected.
