Described herein is a framework to facilitate joining datasets. In accordance with one aspect of the framework, a join request is received from a user interface. The join request may include identifiers for first and second input datasets, as well as one or more join parameters. The join request is automatically converted into a query command based on a query language. The query command is executed to generate an output dataset. An output response including the output dataset may then be sent to the user interface for display.
