Which node in SPSS Modeler is typically the first to receive raw data?

The Source Node is the entry point for bringing raw data into SPSS Modeler. This node is specifically designed to import various types of data from different sources such as databases, files, or streams, allowing the user to begin the data preparation and analysis process. By acting as the primary interface for data ingestion, the Source Node sets the foundation for subsequent analytical steps.

This node is essential as it allows the user to define how data is loaded, including setting up connections to external databases or specifying file paths for flat files. Once the data is in the model, it can be processed and manipulated through other nodes, making the Source Node a critical component in the data workflow within SPSS Modeler.
