Asset Inventory Page

On the Dataphin homepage, click Governance > asset inventory in the top navigation bar to go to the asset inventory page.

Area	Description
①Asset search	You can search for Dataphin assets or assets from other systems by using keywords from the asset's name or description. For more information, see Search For Data.
②Personal data center	You can view assets that you own, have favorited, or are subscribed to. For more information, see Personal data center.
③My Footprints	Recently Viewed: Displays the 30 most recent assets you have viewed. This list is updated in real time. Recently Used: Displays the assets you have recently used for quick access. This list is updated in real time. If an asset has been deleted, you can no longer view its details. Dataphin parses SQL to identify tables the current account uses in features such as ad hoc queries, analytics, and manually executed SQL tasks. It tracks operations such as table definitions (DDL), data modifications (DML), and queries (DQL), and displays up to 30 of the most recently used assets. Recently Favorited: Displays up to 30 of your most recently favorited assets. You can also unfavorite assets from this list. To view all your favorited assets, click personal data center at the bottom of the section. For more information, see View and manage my favorited assets.
④Asset list	You can view the asset list for different types of assets. For more information, see Overview of the Dataphin asset list.

Description

Dataphin asset search

You can search for assets by using keywords from the asset's name or description.

Use the search bar to find any asset within the current tab.
If you have a search history, your recent searches are displayed, allowing you to quickly repeat a search by clicking a previous entry.
Clicking an object in the drop-down list takes you to its details page. If you click the search icon or press Enter, the asset list page for that type displays assets that match your keywords.
If your search for a data table returns no results, this may be because the table was not created in Dataphin or there is a delay in metadata synchronization. In such cases, you can click Sync Manually to fetch the latest metadata. This action refreshes the data table's metadata in Dataphin. For more information about refreshing metadata, see Refresh metadata.

If metadata collection and management is enabled for the current tenant, you can switch between Dataphin and other system assets to view details for different asset types.

You can search for metadata objects by using keywords from their full name or description.
The search bar allows you to search across all assets.
If you have a search history, your recent searches are displayed, allowing you to quickly repeat a search by clicking a previous entry.
