DataFab Onboarding

Version: 1.0 Last Updated: June 2026

Component Overview

Onboarding is the process of activating a new organization on the platform and connecting it to the data sources it will operate over. DataFab supports two onboarding paths that differ in depth: Galaxy (full onboarding, built on the Knowledge Fabric) and Nexus (lightweight onboarding, MCP connectivity only). Both paths terminate in a working environment capable of answering business questions; they differ in how much of the data estate is discovered, mapped, and resolved up front.

The two paths are not mutually exclusive over the lifetime of a tenant — an organization can begin with Nexus and later upgrade to a full Galaxy onboarding once the Knowledge Fabric is licensed.

Onboarding Paths

Galaxy — Full Onboarding (Knowledge Fabric)

Galaxy is the full onboarding path, intended for organizations that have licensed the Knowledge Fabric. It delivers the complete data-unification experience: sources are not just connected but discovered, classified, mapped to schemas, and folded into the knowledge graph.

Best suited for: Large enterprises, multi-division organizations, and any tenant with a dense, multi-source data estate that benefits from automated discovery and entity resolution.

Flow:

1. Tenant activation — A brandable, white-labellable administrative flow provisions and initializes the tenant (licensing, branding, base configuration).
2. Source connection — Internal and restricted external sources are connected over MCP through the Knowledge Fabric.
3. Discovery — The Knowledge Fabric runs automated schema and metadata discovery, scanning each source and tagging tables and columns against the organization’s governing schemas and the ontology glossary.
4. Knowledge graph construction — Monitored entity types (e.g. Customers, Accounts, Persons) are resolved across sources with threshold-based entity resolution and attribute-level conflict detection.
5. Guided initialization — A dialog-guided tour introduces the main configuration areas and performs initial setup.

Delivers: Unified data catalog, automated schema mapping, full entity resolution, and a populated knowledge graph spanning the connected estate.

Nexus — Lightweight Onboarding (Connectivity Only)

Nexus is the lightweight onboarding path for organizations that have not implemented the Knowledge Fabric. It establishes MCP connectivity to internal sources so the tenant can query and reason over them, without the full Knowledge Fabric discovery and active-metadata layer.

Best suited for: Small and medium organizations, individual teams, and any tenant that wants immediate, low-overhead access to its sources without standing up the full Knowledge Fabric.

Flow:

1. Tenant activation — The same brandable administrative activation flow provisions and initializes the tenant.
2. Source connection (Nexus Connectivity) — Internal sources are connected over MCP via Nexus, the connectivity layer for non–Knowledge Fabric tenants.
3. Knowledge graph construction — Knowledge graph construction is available to Nexus tenants as well, providing entity resolution over the connected sources.
4. Guided initialization — The same dialog-guided tour introduces core configuration and performs initial setup.

Delivers: Direct MCP connectivity to internal sources and an entity-resolved knowledge graph, without automated discovery, schema mapping, or active-metadata enrichment.
