How is data consistency between systems ensured?

Data consistency is not a single mechanism but the interplay of several building blocks. Unique identifiers (master keys) link a product or customer across system boundaries, so the same record stays reliably the same in shop, ERP and accounting. Timestamp-based delta synchronization transfers only data that has actually changed, avoiding race conditions and unnecessary load.

Before forwarding, validation rules in the middleware check each record for completeness and plausibility. If a check fails, the record is isolated rather than passed through in a faulty state. Monitoring dashboards show the synchronization status of all data flows, so deviations become visible before they surface in day-to-day business. Which conflict rules apply to your data is something we define together during the analysis phase.
