Identify which enterprise information system (EIS) data source needed.
Consider the synchronization method, how to reduce load on both the EIS and Unwired Platform, and how to trap error messages from the EIS. You may need to write custom code to access legacy systems, filter out unwanted data, identify specific data needed for a mobile business object, and report EIS errors. The propagation of changes and events from the back-end to the consolidated database needs to be considered for applications using the synchronization approach (native applications) and workflow applications to trigger specific workflows.
