Internal arrow: an input, control, or output arrow whose ends connect a source with a consumer that are blocks of the same diagram. It differs from a boundary arrow. 2.32 Junction: A junction at which an IDEF0 arrow segment (going from a source to a sink) merges with one or more other arrow segments to form a single arrow segment. Mechanism Arrow: A class of arrows that represent IDEF0 mechanisms, i.e., the means used to perform a function; includes the special case of the call arrow.

Mechanism arrows are associated with the bottom afghanistan whatsapp number data side of an IDEF0 box. 2.34 Model Note: A text comment that is part of an IDEF0 diagram and is used to record a fact that is not represented graphically. 2.35 Node: A block that generates child blocks; a parent block. (See: node list, node tree, node number, node reference, diagram node number). 2.36 Node List: A list, often in steps, showing the nodes of an IDEF0 model in an ordered fashion. Has the same meaning and content as a node tree. 2.

37 Node Number: A code assigned to a block to indicate its position in the model hierarchy; may be used as a Detailed Reference Expression. 2.38 Node Reference: A code assigned to a diagram to identify it and determine its position in the model hierarchy; formed from the abbreviated model name and the diagram node number with optional extensions. 2.39 Node Tree: A representation of the relationships between parent and child nodes of an IDEF0 model in the form of a tree graph. Has the same meaning and content as a node list. 2.
