This topic describes the concepts, benefits, and differences between DataV Blueprint Editor and node programming.

Basic concept

Blueprint Editor is commonly referred to as Visual Programming or Flow Based Programming. It defines the interaction between layers through visual connections.

Benefits

Different from the previous node programming, Blueprint Editor ensures real-time and synchronization of interaction and data.
Blueprint Editor supports data request merging and data distribution.
Blueprint Editor can be modularized and split to focus on a single interaction link. You do not need to organize and standardize code. You only need to focus on business rules and interaction requirements.
Blueprint Editor supports original components and third-party components. This is a developer-friendly feature.
Important
Third-party widgets developed by users must comply with the developer standards.

Differences between Blueprint Editor and Node Programming

Node programming	Blueprint Editor	Remarks
Triggers added to the canvas	Upgraded to Branch Decision.	In Blueprint Editor, the trigger name is retained in the node name.
Converters added to the canvas	Upgrade the logical node to Serial Data Processing Node.	In Blueprint Editor, the converter name is retained in the node name.
Left-side layer pane	Added Nodes pane, where only the widgets added from Canvas Editor are displayed. If an added widget is removed from Blueprint Editor, this widget is marked with a red exclamation point and its configured interactions become invalid.	None.
Left-side rule template	Manage: You can manage code snippets on the Data Snippets page of the DataV console. Add: In the Configuration panel on the right side of the logical node, right-click the Processing Method field to import the code snippet that is saved as a template to the application.	None.
Preview page in the lower-right corner of the node programming page	The preview function in Blueprint Editor is integrated with the preview function in Canvas Editor.	None.
Application function key in the upper-right corner of the node programming page	The application key function is integrated with the preview page function. The change takes effect immediately without the need to click the application function key.	None.
View logs	Upgraded to Debugging Preview Guide.	None.
