A lot of changes need to be made here - I obviously had the music
on too loud when I reviewed this model! Here we go... |
| The associative object name should be changed to "Part Order" from "Part Delivery". |
| Relationship (R2) should be reversed so that it reads "Part Order is delivered in zero, one or many Delivery Units while a Delivery Unit delivers Parts for exactly one Part Order." I am defining Delivery Unit as a quantity of Parts shipped in a single Box for a given Part Order. If a Part Order is delivered in multiple Boxes, then there would be multiple Delivery Units. The relationship is unconditional on the one-side since you would not create an instance of the Delivery Unit object unless you were fulfilling a Part Order. The definition of Delivery Unit restricts it to deliver parts for exactly one Part Order. It is conditional on the many-side since a Part Order may exist for some time before any Delivery Units have been established. R2 is many because a Part Order may be split across more than one Box. |
| Add the attribute "Order Date" to the Part Order object and extend the bracket on the left to show that Part ID + Destination Site ID + Date constitutes a complete alternative identifier.
(More than one order could be placed requesting the delivery of a Part to an Assembly Site - consequently it is more convenient to assign a single Order ID as the primary identifier). |
| Add the referential attribute "Delivery Unit ID (R2)" to the Part Order object. |
| Last bullet |
It should read "A 1:Mc relationship (R4) is added which connects Box to the new Delivery Unit object." |

Paragraph 3 in object description box. |
It should read "Before the first Event, the value of Parameter is the default value." |
