Bill of Materials

• In a production control environment, a bill of
  materials (BOM) is a data model used to represent
  the relationship of a part to another part.
  Suppose we produce and sell bicycles. Suppose
  further that we have a certain bicycle named
  ExtremeCycle101, and that the parts that go into
  producing this type of bike can be partly
  illustrated as shown below.

The diagram above informs us that an
ExtremeCycle101 I an assembly (it has component
parts) that is constructed from those types of
parts shown at the second level (HandleBarX,
FrameX, SeatB919, Wheel111, ). HandleBarX is a
part, it is not an assembly. Note that FrameX is
another assembly made from a specific frame and
pedals. The type of diagram shown above is called
a parts explosion it can show in great detail
the various part that are required to build the
part shown at the top, at the root. In some
enterprise, a parts explosion could
detail hundreds or thousands of parts. Another
common way to illustrate this information is in a
table such as
