Abstract
A method of accommodating at least one difference between a first database schema and a second database schema is provided. The method includes receiving a response generated by a first application program using a first database schema, identifying a value in the response that is unrecognizable to a second application program using a second database schema and substituting, using a processor, the value that is unrecognizable to the second application program with a reserved element recognizable to the second application program, the reserved element indicating to the second application program that a portion of the response is not recognizable to the second application program. The method further includes communicating the response to the second application program.
