Context Graph stages in dataflows
Context Graph stages perform operations on Context Graph models.
Add Context Graph stages to dataflows created in Enterprise Designer. Context Graph stages may also be incorporated in service dataflows, which can be accessed as web services or using the Spectrum Technology Platform API.
The following Context Graph stages may be added to dataflows in either Enterprise Designer.
| Stage | Description |
|---|---|
|
Delete from Model |
The Delete from Model stage deletes entities and relationships from a Context Graph model. |
|
Import to Model |
The Import to Model stage creates output files and script files that are used as input by the Neo4j import utility that loads the data into the Neo4j database. The data can then be viewed by using the Context Graph clients. |
|
Merge Entities |
The Merge Entities stage merges two or more entities into a single entity. |
|
Read from Model |
The Read From Model stage executes a query to read data from an existing model. |
|
Query Model |
The Query Model stage is an intermediate stage that uses incoming data rows to execute queries that extract specific entities and relationships from a model. |
|
Split Entity |
The Split Entity stage splits one entity into two or more new entities. |
|
Write to Model |
The Write to Model stage uses input data to create or update a Context Graph model that contains entities, relationships, and properties. |
