javascript sequence diagram

In object-oriented dynamic modeling, four types of graphs are used to establish behavior interaction between entities: Stage divisor, sequence divisor, and communication divisor ), activity digraphs, where, "Sequence Chart"And"Collaboration diagram"Similar messages are expressed. A sequence

1. What is a sequence diagram is an interaction diagram that emphasizes the time order of messages. A sequence diagram describes the interaction between classes and classes in a class system, and it models these interactions as message exchanges. A

first, the conceptThe interaction diagram describes the dynamic cooperative relationship between objects and the order of behavior in the process of cooperation. Interaction diagrams are often used to describe the behavior of a use case, to show the objects involved in the use case and the message delivery between those objects, i.e. the implementation of a use case. there are two forms of interaction graph, Order

Object-oriented modelObject-oriented model is a model that uses UML (Unified Modeling Language) to describe the system structure, and it realizes the working state of the system from different angles. These graphs facilitate information exchange between users, managers, system analysts, developers, testers, and other personnel. This article mainly introduces use case diagram, Sequence

It uses the "lifeline" of objects and the messages passed between them to show how objects

parameters can not increase or decrease. Although it is sometimes permissible to add new operations, the semantics (or behavior) of the operation should remain the same.Implementation--The implementation of the component can be arbitrarily changed according to the underlying database, algorithm (such as sort) used, as long as the behavior of the customer's concern is not affected, and can even be written in different programming languages.Use case diagrams are a brief description of the externa

Class diagrams and sequence diagrams are directly associated with program code in software system design. To be precise, program code is directly generated by class diagrams, A Sequence Chart can define a class chart method. The use case diagram is used to describe system functions and has no direct relationship with the sequ
