can use class diagrams to model the business vision of the system. As we will see in this series of articles on the basics of UML, other diagrams-including activity diagrams, sequence diagrams, and state diagrams-reference class modeling and documentation in class diagrams.

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

UML-united modeling language, unified modeling language-is an object-oriented visual modeling language. UML uses a set of visualized graphical symbols (such as class diagrams) as the modeling language. These symbols can be used to visually describe all aspects of the system. UML describes a model by establishing various relationships between graphs (such as the r

state again, it can go directly into the sub-state, rather than starting again from the initial state of the combined state.Concurrency ZoneA state diagram can be divided into regions, and regions include exits or sub-states that are currently executing. Indicates that the combined state can reach multiple sub-states at a time.State Machinedescribes the sequence of states that an object or an interaction undergoes in response to an event during its l

Introduction The learning of UML started on the 3rd and ended on the evening of the 13th. Today (Nov 14), I reviewed UML and refined the following learning tasks. The overall learning of UML is similar, but there are still many areas to be improved. Learning Process At the beginning of UML learning, I first spent half

first, the definition: Time series diagrams (Sequence Diagram), also known as sequence or sequential plots, are UML behavior diagrams. It shows the dynamic collaboration between multiple objects by describing the chronological order in which messages are sent between objects. It can represent the sequence of behavior of a use case, and when a routine is performed, each message in a sequence

1. Introduction to UML UML (Unified Modeling Language) is a visual modeling language that is well defined, easy to express, powerful, and universally applicable. It integrates new ideas, new methods, and new technologies in the software engineering field. Its scope is not limited to supporting object-oriented analysis and design, but also supporting the entire process of software development starting from r
