Database Connections

An OpenEdge application can access one or more OpenEdge or non-OpenEdge databases simultaneously. The databases can be located on different operating systems using different networking protocols. To access non-OpenEdge databases, you must use the appropriate DataServer, such as DataServer for Oracle. You must connect to a database before you can access it. There are four ways to connect to a database:
*As a command-line argument (connection parameter) when starting OpenEdge
*With the CONNECT statement (in the Procedure Editor or in an ABL—Advanced Business Language—procedure or class)
*With the OpenEdge Data Dictionary or other database administration tools
*Using the auto-connect feature
