View business and technical lineage for assets that are available in Data Governance and Catalog. You can also view model lineage specifically for AI Model assets and manual lineage for manual data elements in your catalog.
Based on the asset type, you can view the following types of lineage:
Business lineage
Business assets display business lineage. You can view business lineage for data set and system assets. For example, if you are viewing the lineage for a data set, you can see how data flows between data sets and their associated parent system assets. Business analysts typically use business lineage to understand the source of the data and to ensure that the data is coming from a trusted source.
The following image displays the business lineage for a sample business data set:
Technical lineage
When you view data lineage for a technical data element or a technical data set, such as a column, you can choose to view the technical lineage or the business lineage if that data element is associated with a business data set. Technical lineage allows data architects to drill down to the smallest unit of data, navigate through the entire journey of data from the source to destination, and view data transformations.
The following image displays the technical lineage for a sample technical data set:
Model lineage
AI Model assets display model lineage, a visual representation of the data sets and other AI models that are associated with the AI model. You can view model lineage to identify the data used to train or validate an AI model, as well as understand its dependencies on other AI models.
The following image shows the Model Lineage tab of a sample AI model asset:
If you want to establish a connection between an AI model and data sets, use the Add button on the Data tab of an AI Model asset. To establish a connection between an AI model and another AI model, use the Add Relationships button on the Relationship tab of an AI Model asset.
Manual lineage
Manual lineage displays connections between a manual data element that you created and other business and technical assets. To establish such connections, use the Create Manual Lineage option on the Relationships tab of an asset. When you create a manual lineage, Data Governance and Catalog creates a relationship of the is in Manual Lineage with type between the manual data element and other assets.
