A method for data exchange among computing systems, such as first and second computing systems, that each operate management systems that normally communicate given data to a target computing system in first and second disparate formats. Representative management systems may be a human resource management system (HRMS), and the target computing system operates an application, such as a payroll application, that interacts with the HRMS of each computing system. The first and second computing systems typically are located in first and second geographic locations distinct from one another. The method begins by instrumenting each of the first and second computing systems to respond to a trigger event from an ODBC-compliant data source to generate a WSDL (Web Services Description Language) object that encapsulates the given data, such as human resource (HR) data. The WSDL objects that are generated as a result of the trigger events are received, preferably via a Web service, at the target computing system. The target computing system then processes information in the WSDL objects.
