Asset Map
Definition
This module is used to centrally manage all types of Data Assets in the platform. It supports unified access, identification, and standardized management for structured and unstructured data, improving the visibility, manageability, and controllability of Data Assets.
Primary Data Assets (relational assets)
It supports automatically identifying tables, fields, and other structured Data Assets from connected data sources, and builds a unified asset details page for each asset, providing multi-dimensional views:
- Overview View: displays all field attributes of the asset with no limit on the number of fields, ensuring that asset information is presented completely;
- Asset Lineage: if lineage information has been parsed for the bound data source, you can directly view the upstream and downstream relationship graph of the asset;
- Data Quality: displays bound Data Quality Tasks and reports, supports adding audit tasks, and automatically associates Standard Data Elements;
- Data Cleaning: displays cleaning report information, supports quickly creating cleaning tasks, and automatically matches standard field rules;
- Supports editing settings such as schedule cycles and cleaning/quality rule configurations to implement an asset-level Data Governance closed loop.
Non-relational Data Assets (unstructured)
It supports incorporating unstructured files into the asset system, including documents, images, audio, video, and other content types, and registers and manages them in a unified way.
- Data source access: supports scanning and accessing files from directories such as HDFS, FTP, and OSS, and also supports manual upload;
- Metadata identification: the system can automatically extract basic file information, such as file name, path, type, size, creation time, modification time, and more.
Notes
Asset information display should ensure field integrity and avoid missing fields affecting subsequent lineage, quality, cleaning, and other functions. For unstructured asset access, we recommend managing files together with file directory naming conventions.
Scope
Applicable to modeling and managing all structured assets (such as database tables) and unstructured assets (such as files, audio, and video) in the platform. It supports full-lifecycle governance of asset information and is widely used in Data Map, Data Quality, cleaning, lineage, and other submodules.
1. Asset Map Page
Click Data Assets under Asset Map to open the Asset Map page. The page uses a left-right layout: the left side displays asset categories in a tree structure, and the right side displays the Data Assets list view, including asset name, identifier, asset description, category, topic, data tags, and other fields.
2. Add Asset Map
Click Add, fill in Asset Map information in the dialog, and click OK to complete adding the Asset Map.
3. Publish
Select the Asset Map to publish, click the Publish button in the list view, and click OK to complete publishing the Asset Map.
4. Unpublish
Select the Asset Map to unpublish, click the Unpublish button in the list view, and click OK to complete unpublishing the Asset Map.
5. Asset Map Details
Select the Asset Map whose details need to be viewed, click Details in the list view, and view the detailed Asset Map information on the details page, including user information, attribute fields, and Data Preview.
5.1. Attribute Fields
On the Asset Map details page, click Attribute Fields to open the Attribute Fields page. The page includes fields such as Chinese name, English name, field type, field length, decimal places, nullable, primary key, Sensitivity Level, code flag, and Data Element.
5.1.1. Edit Attribute Fields
Select the attribute field to edit, click Edit in the operation column, edit the Attribute Fields information in the dialog, and click OK.
5.2. Data Preview
On the Asset Map details page, click Data Preview to open the Data Preview page.
6. Update Data
Select the Asset Map whose data needs to be updated, click More -> Update Data in the list view, and the data update operation will be triggered.
7. Request Data Asset
Select the Asset Map for which you need to request a Data Asset, click More -> Request in the list view, fill in the asset request information in the dialog, and click OK to complete the request.
8. Delete
Select the Asset Map to delete, click More -> Delete in the list view, confirm the deletion in the dialog, and click OK to complete the delete operation.
