sequence diagram, a sequence receives and sends messages (also known as interactions). A model can be established by connecting the message and the Framework Element Boundary (see figure 2 ). For a sequence chart, the label of the chart starts with the text "sd. When you use a frame element to close a graph, the label of the graph must follow the format below: Graph type graph name.

of being able to add multiple abstract methods with stronger representation capabilities. 3) Association class Like a class, association can also have its own attributes and operations. In this case, this association is actually an association class. An association class is both an association and a class. It connects two classes like an association, and can define a group of characteristics that belong to the association itself. Note: you can create an association class only when the 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
