13+ Uml Sequence Conditional. This is a sequence diagram example that uses mvc stereotype with conditional statements. Uml sequence diagrams are used to represent or model the flow of messages, events and actions time is represented in the vertical direction showing the sequence of interactions of the header.
A sequence diagram simply depicts interaction between objects in a sequential order. A uml sequence diagram is used most commonly to show the realization of a use case in terms of interactions between business entities or software objects. A uml sequence diagram shows how messages go back and forth between objects over time.
It shows the messages that pass between participants and objects in the system, and the order in which they occur.
13+ Uml Sequence Conditional. The sequence diagram differs from the uml application case diagram in particular by its detailed order. To support conditional and looping constructs (among many other things), the uml uses frames. A sequence diagram shows object interactions arranged in time sequence. It depicts the objects involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario.
