Overview

A business domain represents a subset of all your data assets. Domains are useful to provide a view of specific business areas such as Finance, Marketing or Sales. It can also provide different access to different teams such as the data team, data consumer team etc.

Users in a given domain will be able to focus on this particular scope.

Manage Domains

📘

Prerequisite

Only users with the Admin system role can manage domains.

Create a Domain

To create a new domain:

• Hover the Settings menu on the navigation bar and click the Domains entry
• Click on the + New domain button at the top right hand corner of the page
• Name your domain
• Add a description to your domain
• Choose one of the two available methods to add assets to your domain:
  • Filter conditions: Specify filters for your domain to automatically include any asset matching those filters in your domain.
  • Select data assets: Select all the assets you want to add to your domain.

Filter conditions

The Filter conditions selection method lets you define criteria to automatically include any asset matching those filters in your domain.

To define filter conditions for your domain and save it:

• Click the Filter conditions button
• Define the appropriate filter conditions for your domain.
  • You can use one or a mix of the following filters:
    • The Sources filter allows you to associate all assets coming (is operator) or not coming (is not operator) from specific Sifflet sources.
    • The Source tags filter allows you to associate all assets tagged (is operator) or not tagged (is not operator) with specific inherited tags (supported for Snowflake and BigQuery).
    • Note: If you select multiple sources or source tags within a given condition, the operator that automatically applies within that condition is an OR.
  • You can choose to apply an OR or an AND operator between your conditions.

• Click the Save domain button to save your domain.

Filter conditions apply both at the time of domain creation and afterward, ensuring your domain stays current with the latest data changes. By automatically reflecting additions or removals of assets based on the defined filters, it simplifies maintenance and keeps your domains up to date.

Example: Suppose the Marketing domain is defined to include all assets where Sources is marketingor analytics. Upon saving this domain, any asset from the marketing or analytics BigQuery datasets are automatically added to the Marketing domain.

The Marketing domain remains dynamic after its creation. For instance:

• If a new table is added to the marketing BigQuery dataset a week after the domain's creation, the Marketing domain automatically includes the new table in its definition.
• If a table is removed from the analytics BigQuery dataset two weeks after the domain's creation, the domain automatically excludes the removed table from its definition.

Note: An asset can belong to multiple domains.

Select data assets

The Select data assets selection method lets you select all the assets you want to add to your domain.

• Click the Select data assets button
• This opens up the Data Catalog in a modal. Leverage filters, search, and sorting capabilities to narrow down your search and use checkboxes to select the assets you want to add to your domain.
• Once you're done selecting your assets, click the Save button to close the Data Catalog modal and click the Save domain button to save your domain.

Note: An asset can belong to multiple domains.

Ownership & Domains

Users can only be owners of assets they have access to through domains. When modifying or deleting domains, keep in mind that it might impact assets ownerships: deleting a domain can for instance prevent a user from accessing some assets they own and consequently remove the said ownership link between the user and assets.
