For the system analysis process that produces the conceptual description, object-oriented techniques or semantics extensions are utilized. Object-oriented methods and languages (e.g., UML) are typically used for describing the software system. This research also presents the application of MIMECORA-DS in a case example, to assess its applicability.īuilding an information system involves two processes: conceptual modeling of the “real world domain†and designing the software system. In this paper it is presented an extension based on the default UML meta-model, named MIMECORA-DS, to show object-object, object-aspect and aspect-aspect interactions applying the UML's sequence diagram. The application of UML to this area is the subject of constant study and is the focus of this paper. Since the UML is a standard for modeling OO systems, it can be applied to model the decoupling between aspects and OO components. Guerra, Eduardo M.ĪOP and its broader application on software projects brings the importance to provide the separation between aspects and OO components at design time, to leverage the understanding of AO systems, promote aspects' reuse and obtain the benefits of AO modularization. Whereas previously, the construction of sequence diagrams was a tedious manual process, Rational Sequence generates UML sequence diagrams automatically from the running Java code.Ī Collaborative Support Approach on UML Sequence Diagrams for Aspect-Oriented Softwareĭe Almeida Naufal, Rafael Silveira, Fábio F. Rational Sequence thereby performs a reverse engineering function that aids in the design documentation of the target Java program. The best way to understand sequence diagrams is to look at some examples of sequence diagrams.Program Synthesizes UML Sequence DiagramsĪ computer program called "Rational Sequence" generates Universal Modeling Language ( UML) sequence diagrams of a target Java program running on a Java virtual machine (JVM). Sequence Diagram and Other UML Diagram Examples It's shown by an arrow going from a lifeline to an endpoint, a filled circle or an x. It can be shown by an arrow with an x at the end.Ī message sent from an unknown recipient, shown by an arrow from an endpoint to a lifeline.Ī message sent to an unknown recipient. This is a message that destroys an object. Similar to a return message, it's depicted with a dashed line and an open arrowhead that points to the rectangle representing the object created. This is a message that creates a new object. Like synchronous messages, they are drawn with an arrow connecting two lifelines however, the arrowhead is usually open and there's no return message depicted.Ī reply message is drawn with a dotted line and an open arrowhead pointing back to the original lifeline.Ī message an object sends to itself, usually shown as a U shaped arrow pointing back to itself. It's usually drawn using a line with a solid arrowhead pointing from one object to another.Īsynchronous messages don't need a reply for interaction to continue. Ī synchronous message requires a response before the interaction can continue. Place the condition for exiting the loop at the bottom left corner in square brackets. When that object's lifeline ends, you can place an X at the end of its lifeline to denote a destruction occurrence.Ī repetition or loop within a sequence diagram is depicted as a rectangle. Objects can be terminated early using an arrow labeled ">" that points to an X. ![]() Lifelines are vertical dashed lines that indicate the object's presence over time. Asynchronous messages are sent from an object that will not wait for a response from the receiver before continuing its tasks. Use half-arrowed lines to represent asynchronous messages. Messages are arrows that represent communication between objects. When an object is busy executing a process or waiting for a reply message, use a thin gray rectangle placed vertically on its lifeline. Use the UML object symbol to illustrate class roles, but don't list object attributes.Īctivation boxes represent the time an object needs to complete a task. Start Now Basic Sequence Diagram NotationsĬlass roles describe the way an object will behave in context. ![]()
