What distinguishes a data source from a raw data file in SAS Enterprise Miner?

A data source in SAS Enterprise Miner is distinguished from a raw data file primarily by the additional attached metadata. This metadata provides essential information about the data, such as variable types, formats, labels, and missing values, which helps users understand the context and structure of the data. The presence of metadata enhances usability and interpretability, facilitating proper data manipulation, reporting, and analysis within the SAS Enterprise Miner environment.

While size, ease of access, and file format can differ between a data source and a raw data file, they do not specifically characterize the data source in the same way that metadata does. The focus on additional attached metadata captures the essence of what makes a data source more than just a raw data file, as it enriches the data's descriptive capabilities.
