# Single Instance Data

**Single instance data** refers to a digital bridge or unified architecture where operational data from across the entire enterprise (manufacturing, logistics, procurement, fulfillment) is organized into common standards and made universally accessible. By creating a single, authoritative source of truth, an organization eliminates the contradictions that arise when different departments operate on siloed datasets — precisely the pathology described in [[concept-broken-data-foundation]].

This unified data layer is the mandatory prerequisite for building an integrated AI architecture that can coordinate decisions across multiple business functions in real time. It is the concrete deliverable of [[concept-digital-transformation-1-0]] and the foundation on which [[concept-ichain-architecture]] is built — specifically the *data intelligence* layer in [[framework-ichain-layers]]. Achieving it demands the deep data-engineering competence flagged in [[prereq-data-standardization]].

> **Enrichment note:** Modern data-stack and lakehouse architectures (Databricks, Snowflake) echo the "single instance" idea with different technical implementations; the concept is well established even if Lenovo's terminology is specific to this case.

**Definition:** A unified enterprise data architecture that organizes operational data from all departments into common standards, creating a single accessible source of truth.
