This layer of code communicates with the DataBase or DataStructure where the data is stored and brings that data out of it. This layer does all the complex activity and communicates with the datalyer. This layer of the code provides the business logic for the front end of the application. This layer of the code is the View part that is to be displayed to the end user of the application, in other words the front end of the application. Read more on this : Sequence diagram Now in the following way I designed my code and than I will show the sequence of this code. Sequence diagrams are typically associated with use case realizations in the Logical View of the system under development.

It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. A sequence diagram shows object interactions arranged in time sequence. It is a construct of a Message Sequence Chart. (The following description is from Wikipedia.)Ī sequence diagram is a kind of interaction diagram that shows how processes operate with one another and in what order. However on other hand Collaboration diagrams is used to describe the general organization of system for several objects in several use cases.The following article is about a feature provided by Microsoft Visual Studio to generate a sequence diagram from existing code.īefore getting into the details of how Visual Studio generates the sequence diagram, the following describes what a sequence diagram is. Sequence 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.

On other hand Collaboration diagram mainly represent organization of system so it is not classified as Dynamic modelling diagram. On other hand Collaboration diagram focus to represent the structural organization of the system and the messages that are sent and received.Īs Sequence diagram models the sequential logic, ordering of messages with respect to time so it is categorised as Dynamic modelling diagram. It is time ordered that means exact interactions between objects is represented step by step. Sequence diagram mainly focuses to represent interaction between different objects by pictorial representation of the message flow from one object to another object.

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. Sequence 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. 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.įollowing are the important differences between Sequence Diagram and Collaboration Diagram − Sr.
