The collaboration diagram and sequence diagram shows similar information but in a distinct form. It can portray the architecture of an object inside the system. It can be used to depict the relationship among various objects within the system. The collaboration diagram shows the nature of a specific use case. Sequence diagrams map out complex architecture, but they can be surprisingly easy to create. Sequence diagrams are a popular subset to UML, so if you’re new to the topic, use our sequence diagram tutorial to familiarize yourself and find different ways you can use sequence diagrams to map out your technical process and infrastructure. .Sequence diagram emphasizes on time sequence of messages. Collaboration Diagram emphasizes on the structural organization of the objects that send and receive messages. It is a illustration of the relationship and interaction among software objects in the UML.

Frozen (Constraints) (Figure 2)

·A Constraint {i.e.: Read only attribute}.

·Constant cannot change.

oE.g.: A person’s SS# cannot change once set.

·Association or association end cannot change.

Derived Associations and Attributes (Figure 2)

  • Calculated from other associations and attributes on a class diagram.
    • E.g.: an age attribute of a person can be derived if you know that person’s DOB.

Association Class (Figure 2)

·An intermediate class among two or classes.

oE.g.: A Person object might be related to a Company object via an Employment
object(Association class).

Multiple and Dynamic Classification

·Refers to the relationship between an object and its type.

·Single Classification: an object belongs to a single type.

·Multiple Classification: an object may belong to many types may or may
not be related.

·Dynamic Classification allows objects to change type within an inheritance
structure; Static Classification does not.


qAbstract Class

·Use Italic or the constraint {abstract}.

·Interfaces in Java and Abstract Base Classes in C++.

·Provides the important OOD concept of implementation hiding.

qReference Object and Value Objects

Reference Object

·Only one object is permitted.

·To see if two object handles refer to the same reference object,
compare object handles.


Value Objects

·Multiple copies are allowed.

·Compare their values.

qSpecialization (Classification) and Generalization(Figure 3)

·Beware! Class responsibilities can be confused.

·Generalization is transitive.

·Specialization is not.


  • Generalization

·'is-a-kind-of', 'is-a-type-of'.

  • Car is a type of vehicle.



  • Bill smith is an instance of a student.

qQualified Association (Figure 3)

·UML’s ways to deal with concepts such as Maps, Associative Arrays,
Dictionaries, etc.

qParameterized Class (Figure 4)

  • Generic programming or C++ templates (e.g. STL).
  • Code reuse among semantically similar families of classes.
    • Associative arrays, maps, dictionaries, etc.

qVisiblity (Figure 5)

·Simply is the Encapsulation and Information Hiding concept in OOP.

Both Sequence and Collaboration Diagram are the type of Unified Modelling Language (UML) which is nothing but the pictorial representation of any behavioural flow but on the basis of what each of them emphasis we can distinguish between them.

Following are the important differences between Sequence Diagram and Collaboration Diagram −

Sr. No.KeySequence DiagramCollaboration diagram
1DefinitionSequence diagram is the diagram in which main representation is of the sequence of messages flowing from one object to another; also main emphasis is on representing that how the messages/events are exchanged between objects and in what time-order.On other hand, Collaboration diagram is a diagram in which main representation is of how one object is connected to another implementing the logic behind these objects with the use of conditional structures, loops, concurrency, etc.
2Main focusSequence diagram mainly focuses to represent interaction between different objects by pictorial representation of the message flow from one object to another object. It is time ordered that means exact interactions between objects is represented step by step.On other hand Collaboration diagram focus to represent the structural organization of the system and the messages that are sent and received.
3TypeAs Sequence diagram models the sequential logic, ordering of messages with respect to time so it is categorised as Dynamic modelling diagram.On other hand Collaboration diagram mainly represent organization of system so it is not classified as Dynamic modelling diagram.
4UseCaseSequence diagram as already mentioned is used to describe the behaviour of several objects in a particular single use case with implementation of all possible logical conditions and flows.However on other hand Collaboration diagrams is used to describe the general organization of system for several objects in several use cases.
