What is the Purpose of an IBD? - 🧠 ANSWER ✔✔Display the structure of a
single block and display usages of a block with part properties and
reference properties.
,What does an IBD convey? - 🧠 ANSWER ✔✔The structure of a single
block, services provided or required by parts, and types of matter data and
energy that can flow across connections.
2 Diagrams that show complementary views of a block - 🧠 ANSWER
✔✔IBD and BDD
Allowable Model Element for IBD - 🧠 ANSWER ✔✔block
What is a connector? - 🧠 ANSWER ✔✔Used to show specific connections
among the internal part properties and their connections to external
reference properties.
What is a part property? - 🧠 ANSWER ✔✔It is an internal structural element
of a block.
It is seen as a solid boundary rectangle with name : type [ ].
Multiplicity can either be in brackets or in the top right of the rectangle.
What is a reference property? - 🧠 ANSWER ✔✔It is a structure that is
external to a block.
It is needed by the block to invoke a behavior or service.
,It is represented by a dashed boundary rectangle with name : type
[multiplicity].
Multiplicity can be shown in brackets or the UR corner of rectangle.
What is an Item Flow? - 🧠 ANSWER ✔✔It is used to display matter, data, or
energy flowing between 2 connected flow ports.
It is represented by a filled in arrowhead that is placed directly onto a
connector.
The type of the item flow is named in a label that floats near the arrowhead.
What is Dot Notation? - 🧠 ANSWER ✔✔It is a way to create nesting of a
relationship.
The block that types the property is NOT listed or the multiplicity.
It conveys a structural hierarchy ownership of a property.
What is the Purpose of a Use Case Diagram? - 🧠 ANSWER ✔✔It is a
black-box view of the system.
It conveys the visible external structures that a system performs.
It displays the actors that participate and invoke the use cases in the
diagram during execution.

, What is a system boundary? - 🧠 ANSWER ✔✔A system boundary is the
subject of the diagram and NOT the namespace.
It encapsulates use cases and actors in the diagram.
It is represented as a large rectangle within the diagram frame.
What is a Base Use Case? - 🧠 ANSWER ✔✔A base use case is directly
invoked by an actor.
It is the primary goal of the actor.
When invoked it will invoke a use case with the include relationship.
It has an association relationship.
What is the <<include>> relationship? - 🧠 ANSWER ✔✔It is a UC
relationship where the included use case behavior is required.
Source = tail end
Target = arrowhead end
The use case at the source end is the base use case and the arrowhead
end is the target included use case.
