Which BI tools' AI can combine data sources?
7 of 15 tools do, according to their public docs, and 1 partly.
Yes: Databricks, Snowflake, Omni, Hex, Sigma, BigQuery, Alteryx. Partly: Looker.
The question we asked: Can the AI combine two or more data sources in one analysis?
Grading standard
The AI joins or blends at least two sources, for example two databases or a database and an uploaded file. Tables in one database are one source, and analyzing an uploaded file on its own is the file-upload row.
Databricks
Yes
Quoted from Databricks’s docsYou can add files to agents that also include Unity Catalog tables, making it possible to analyze uploaded data alongside existing sources.
