Data Integration
Definition
Data integration is the work of connecting different systems — ERP, WMS, TMS, supplier and carrier platforms — so data flows between them automatically, accurately, and in a consistent format.
In Practice
Supply chains run on many specialized systems, and integration is what makes them behave like one. Techniques range from EDI batches and API calls to middleware (iPaaS platforms like Boomi or MuleSoft) and data pipelines feeding a central warehouse. Good integration includes mapping (this system's 'EA' equals that one's 'EACH'), error handling, and monitoring.
For practitioners, integration quality silently determines everything else: a visibility platform is only as good as the milestones flowing into it, and a planning system fed stale inventory positions will plan confidently and wrongly. Most 'system problems' blamed on an application trace back to a broken or lagging interface.
Example: when a company's WMS-to-ERP inventory sync fails silently for two days, planning releases orders against phantom stock; the fix is not a new WMS but interface monitoring that alerts within minutes of a failed sync.
