Terminology
The terminology that Metagraphs uses.
- Asset
- A specific data object or Data Lake view.
- Asset catalog
- A catalog containing the list of data objects and Data Lake views stored in Data Catalog. Use this widget to search for and select the asset to add to your model.
- Publish
- To create a view in Data Lake based on the information defined in a metagraph model.
- Node
- Represented as a circle in the metagraph model. Each node represents a single asset.
- Primary node
- The node that acts as the starting point in the metagraph model. When publishing a view
to Data Lake, the asset associated with this node is used as the
initial query table in the
FROMclause of the generated query. - Modeling canvas
- The main part of the modeler where nodes and relationships are added and defined.
- Category
- Assets are grouped together by category. The two categories supported in Metagraphs are Data Objects and Data Lake Views.
- Default properties
- When publishing a view for a metagraph, select the properties to include in that view from each of the nodes in your model. Default properties are the properties that are pre-selected for you at the time the view is created. For details on how to set these properties, see Managing default properties.
