Multi-database connection considerations

When you develop a multi-database application, keep in mind the following information on database connections:

Connect all databases accessed by the application at compile time. Once compiled, the application can run no matter where you store the databases or how you connect to them.
Establish unique logical names for each of the databases you connect. Use these names to reference the databases within your application. These names are stored in the r-code of the application at compilation time. For more information on logical database names, see the "Logical database names" section.
