User Defined Routines (UDRs), capable of being expressed in one or more languages, are handled by determining a language native to the UDR, for example, by looking up a system catalog. If a language manager associated with the native language has not been loaded already, the language manager is loaded into a server memory. If the UDR has not already been instantiated, the UDR is instantiated and initialized. Then an execution context for the UDR is created and the UDR is executed. Loading of the language manager is handled by a general language interface capable of initializing the language manager, loading the language manager, creating a language manager context, and executing the language manager.
