6 elements allowed on a BDD - ANS-Blocks, Actors, Value Types, Constraint Blocks,
Flow specification,
interfaces.
Blocks serve as ________ to other models elements - ANS-types
3 structural relationships - ANS-associations, generalizations, dependencies
6 Model types that the BDD frame can represent - ANS-Package, model, model library,
view, block, constraint block
Block - ANS-basic unit of structure. represents a TYPE of entity not an instance.
Element of definition
Element of Usage represents a _______ - ANS-instance/instantiation
Elements of definition only have a _________ - ANS-Name no colon or type
Elements of Usage have two things: _____ & _____ - ANS-a name and a type
(name:type)
two types of features: - ANS-Structural (properties) & Behavioral
Five kinds of structural features a.k.a properties - ANS-Part, reference, value, constraint
properties and ports
Part property represents what? - ANS-Represents a structure that is internal to a block.
A Block is composed of its __________? - ANS-Part Properties
Reference Property represent what? - ANS-A structure that is external to the Block.
Reference properties do not represent ownership.
what relationship does a reference property represent? - ANS-A NEEDS relationship
Reference property is type by ______ & ________ - ANS-Block or Actor
,What does a value type represent? - ANS-a quantity. it is something you can assign a
number to degrees or Lbs
Value properties are typed by ________? - ANS-value type
What does a constraint property represent? - ANS-a mathematical relationship that is
imposed on a set of value properties.
What types a constraint property? - ANS-Constraint block. this constraint block usually
encapsulates a mathematical relationship
What is a Port? - ANS-a kind of property that represents a distinct interaction of a
structure with external entities either to provide a request for service or to exchange
matter, energy, or data.
When you add a port to a block you are modeling a _________ as a ______ _______ -
ANS-structure & black box
What does a Port represent? - ANS-Any type of interaction point you need to model
Standard Port - ANS-specifies an interaction point with a focus on the services
(behaviors) a black box provides
Flow Port - ANS-Allows you to specify an interaction on the types of matter, energy, or
data that can flow in or out of a structure.
Flow ports model what? - ANS-the types of matter, energy, and data that can flow in or
out of a block.
Nonatomic flowport - ANS-used to model multiple types of items that could flow in and
out of a port
Nonatomic flowports are typed by? - ANS-Flow specification
What are the two kinds of behavioral features? - ANS-Operations & Receptions
What is an Operation? - ANS-a behavior that a block performs when a client calls it. It is
invoked by a Call Event.
,What is a reception? - ANS-A behavior that a block performs when a client sends a
signal that triggers it. A reception is invoked by a Signal Event.
Receptions always represent what type of behavior? - ANS-Asynchronous
What is a Signal? - ANS-A model element that represents any type of matter, energy, or
data
Can signals own properties? - ANS-Yes
A structure is an eligible target for a signal if it owns a reception that has the same
________ as the incoming signal? - ANS-Name
What are the three main relationships between blocks? - ANS-Association,
generalization, dependency
A part property is equal to what association? - ANS-Composite association
Reference Association represents this. - ANS-A connection between blocks in an
operational system
Composite Association conveys what? - ANS-Structural decomposition
A role name shown on the part end of a composite association corresponds to what? -
ANS-The name of a part property
Multiplicity on the Composite end is restricted. - ANS-True. A part can only belong to
one composite at a time.
Each composite association represents this - ANS-a distinct part property
What does a generalization association convery? - ANS-Inheritance between two
elements.
How are generalization associations read in plain english? - ANS-"is a type of" going
from Supertype to Subtype
Substitutability - ANS-A subtype will always be accepted where the supertype is
required.
, Dependency association - ANS-One element (the client) depends on another element
(the supplier)
The dependency association is drawn from the ______ to the ______. - ANS-Client to
the supplier
Actor - ANS-Represents someone or something that has an external interface with your
system
Value Type - ANS-element of definition. generally defines a type of quantity
Variables in a constraint expression are called _____? - ANS-constraint parameters
Constraint block - ANS-Element of definition. Defines a boolean constraint expression
Constraint Expression - ANS-is a mathematical relationship used to constrain value
properties
Constraint parameters - ANS-are variables within a constraint expression
Elements of Definition are called what? - ANS-Classifiers
Classifier: - ANS-A model element that defines a Type that can be built of instantiated
A BDD is used to display what? - ANS-Classifiers
A "Type" is a definition of what? - ANS-Something that could exist
An Instance is an object that ______ or ________ exist in the real world - ANS-Will or
Does
A BDD is like a __________ that expresses the potential of something that
__________. - ANS-Blueprint, could be built.
A ________________ represents a peer to peer association. Two things that are
external and connected to each other. - ANS-Reference Association
What are the 2 types of features you can add to a Block? - ANS-Structural and
Behavioral
