Source

Overview

Source in the dataflow diagram represents an input object supplied by a connector. It shows where external data enters the model and how that data can feed imports, exports, transformations, references, and downstream warehouse objects.

Function

A source object appears as a selectable label on the dataflow diagram. Users can focus it in the navigation tree, use it as a diagram filter, preview its data, refresh its structure, open its reference diagram, or start related import and export work from the same context.

Double-clicking a source opens the source editor. The editor maintains the source name, schema, connector, group, type, friendly name, description, path, query, directory options, and column definition. File-based sources also expose CSV and directory settings, while query-based sources use the Query tab.

Refresh actions compare the source definition with the connected data provider and can update columns, keys, descriptions, imported-table metadata, and source references. This keeps the diagram and the source editor aligned with the external structure used by the model.

Access

Sources can be listed from the Sources toolbar tab, managed from the Sources branch in the navigation tree, and opened directly from a visible source label on the dataflow diagram. The diagram canvas also supports adding a new data source from the Add menu.
