Most reports specify their data sources by setting the ConnectionString and RecordSource properties. The DataSource object uses these values to connect to a database and retrieve the report data.

Alternatively, you can assign data objects directly to the Recordset property. This approach is more efficient in scenarios where the data has already been loaded by the application for other purposes, and can be used in the report directly instead of loading a copy.
