Add an Existing Stream

2. Drag a stream from the repository into the diagram. PhixFlow adds the stream with a list of all of its attributes.
3. If the stream has many attributes, click  to collapse the stream so that it only shows the primary and foreign keys.

Connect Attributes

To connect attributes in different streams, click-drag from one attribute to another. PhixFlow shows the currently selected destination in bold. Release the click to connect to the selected destination.

PhixFlow can only connect primary and foreign keys. This creates a one to many relationship. If you connect standard attributes, PhixFlow automatically sets them to be foreign keys.

PhixFlow automatically sets the type of relationship according to the keys:
