Data Fusion Services

Data Fusion Services, or DFS, is the operational data layer for FactVerse. It connects source systems, maps source data to operational targets, checks data quality, and prepares governed datasets for Inspector, AI Agent, Twin Engine, Designer workflows, and reporting.

Use this section when you need to make real operational data usable in a digital twin workflow.

Source systems
  -> DFS Lite connectors
  -> mappings, sync logs, quality checks
  -> DFS Pro datasets, fusion tasks, review queues
  -> FactVerse apps, AI Agent workflows, dashboards, and field operations

When to use DFS Lite

Use DFS Lite when the job is to connect and operate data feeds.

Typical tasks:

• connect OT, IoT, enterprise, file, API, and database sources;
• test a connector before saving it;
• start, pause, or sync a connector;
• browse a source hierarchy;
• preview sample values;
• map source fields to assets, points, and target fields;
• check sync history, throughput, quota, and data quality.

Start with Getting Started with DFS if this is the first source in the tenant.

When to use DFS Pro

Use DFS Pro when the job requires governed data assets, repeatable data processing, review, or multi-source fusion.

Typical tasks:

• create datasets from connectors, imports, extractions, or fusion outputs;
• validate datasets and assign a data steward;
• review schema versions, lineage, profile, and change impact;
• create reusable processing methods;
• run fusion tasks across multiple datasets;
• review conflicts, low-confidence outputs, and rejected rows;
• use reviewed outputs in AI Agent workflows or BI dashboards.

Start with DFS Pro Datasets when a connector feed needs to become a reusable data asset.

Product boundary

DFS prepares and governs the data foundation. Customer source systems remain the systems of record unless a project explicitly defines a different ownership model.

AI-assisted mapping and LLM-assisted fusion are reviewable suggestions. The reviewed workflow, assigned owners, and audit trail decide whether a mapping, fusion result, or rejected-row correction is accepted.

Common DFS workflow

Phase	DFS area	Result
Connect	DFS Lite connectors	A source is reachable and can be tested.
Inspect	Browse and preview	Candidate fields, tags, rows, or topics are visible.
Map	DFS Lite mappings	Source values are bound to target entities and fields.
Sync	Connector sync	New values are ingested with run history.
Check	Data quality	Completeness, timeliness, accuracy, and quota are visible.
Govern	DFS Pro datasets	Data is packaged as a stewarded asset with lifecycle and versioning.
Fuse	DFS Pro fusion tasks	Multiple datasets are merged with conflict handling.
Review	Review and rejection queues	Uncertain outputs and rejected rows are resolved by a reviewer.
