DataVault Hub

Overview

DataVault Hub identifies a Data Vault hub table in AnalyticsCreator. Use this table type for the central business-key table that anchors satellites and links in a Data Vault model.

Function

A DataVault Hub table represents the stable key for a business object. It is created from a source table with a primary key and can be historized during the hub creation flow.

In the table editor, DataVault Hub is handled as a managed table type. The table name and structural column definitions are protected from direct editing, while business metadata such as friendly name, description, scripts, dependencies, and table definition remain available for review and maintenance.

The Vault Wizard creates the related hub transformation and, when historization is selected, the hub table and historization package details. The wizard requires a source table, transformation schema, transformation name, hub schema, hub name, and history package when a historized hub is created.

Access

Open an existing DataVault Hub table from the Tables list or from the navigation tree. To create a new hub, use the diagram Add menu and choose Data vault hub.
