DataVault Link

Overview

DataVault Link identifies a Data Vault link table in AnalyticsCreator. Use this table type to model relationships between business keys, such as the association between two or more hub-driven entities.

Function

A DataVault Link table represents a relationship in the Data Vault model. It is created from a source table with a primary key and at least one selected referenced table in the link creation flow.

In the table editor, DataVault Link 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 link transformation and, when historization is selected, the link table and historization package details. The link tab can also create a LinkSat by providing a LinkSat name, LinkSat package, and the referenced tables to include.

Access

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