Datasource

In Sympathy for Data, the action of pointing out where data is located and actual importation of data are separated into two different categories of nodes. The internal data type Datasource is used to carry the information about the location of the data to the importation nodes.

There exist two nodes for establishing paths to locations with data, either you are interested in a single source of data, Datasource, or several sources, Datasources. The single source can either be a data file or a location in a data base. While for multiple sources only several data files are handled.
