shows a sequence chart for calculating the cumulative amount in a transaction. The call starts from the calctotal () method of the sale class.CodeThe segment is given after the sequence diagram. Glossary: UML defines an operation as a signature of a method ). The term "method" is reserved for the code that implements the operation. However, in the

in Java. The difference between Association and aggregation is purely conceptual and strictly reflected in semantics. Aggregation also implies that there is no loop in the instance diagram. In other words, it can only be a unidirectional link. Figure F Composition) Synthesize (Figure G) Is a special form of aggregation, suggesting that "local" is responsible for the lifetime of the "whole. Synthesis is n

understand the component: Class Component Logical Abstraction Physical Abstraction You can directly own properties and operations Generally, you only have operations that can be queried through the interface. To sum up, components have the following features: The component is physical. Component is replaceable Components are part of the system The component follows a group of interfaces and provides implementation for a group of interfaces. Compared wi

there is no loop in the instance diagram. In other words, it can only be a one-way relationship. Figure F Synthesis (composition) Synthesis ( fig. G) is a special form of aggregation, implying "local" within the "whole" life-cycle responsibility. Synthesis is also not shared. Therefore, while the part does not necessarily have to be destroyed with the destruction of the whole, the whole is either responsible for maintaining a partial survival state o

the OO principle, we need to put forward the name attribute separately, and then let other classes inherit. Next let's take a look at the generated code to see if it is exactly the same as the class diagram description. (double-click) any class diagram. Hey, is it a little interesting. Well, we have mastered the class graph 20% so far. You only need to

UML defines the following 5 categories, 10 model diagrams. The first class is the use case diagram, the use case diagram describes the function of the system from the user's point of view, and points out the operator of each function. The second category is static diagrams, including class diagrams, Object diagrams, and package diagrams. The class

Instance analysis 1-Logon Module The function of a C/S-based Real-time chat system logon module is described as follows: The user enters the account and password through the loginform interface. The system compares the entered account and password with the user information stored in the database (User) table to verify whether the user input is correct, if the input is correct, enter the main interface (mainform). Otherwise, the system prompts "incorrect input ". Draw an initial class

, the Association and the aggregation cannot distinguish syntactically, must examine the concrete logical relation. "Code embodiment": member variable "Arrows and points": solid lines with hollow diamonds, diamonds pointing to the whole 5. Combination (composition) "Combinatorial relationship": the relationship between the whole and the part, but part cannot leave the whole and exist alone. If the company and the Department is a whole and part of the

Using a few modeling design tools, small have staruml, large have rational rose,ea. The final discovery or Visual Studio modeling is more comfortable (personal view, don't argue).I'm going to make an introduction to a few of the modeling diagrams that I use often, such as Class diagram (class Diagram), Time series diagram (sequence

Clear definition of the system boundary, the performer angle naming use case three, example This figure includes a total of 3 roles for general users, operators, and administrators. Contains the following relationships: 1. Association: Divided into two-way and one-way, generally the relationship between roles and use cases 2. Generalization: The common behavior of cer

Composition) [Composite relationship]: it is the relationship between the whole and the part, but the part cannot exist independently from the whole. If the relationship between a company and a department is a whole and a part, no department exists without the comp

This article begins with a discussion of code-level issues. The main feature of Markdown is the design implementation.This article begins with the markdown perimeter code:UML sequence diagrams are obtained from https://github.com/bramp/js-sequence-diagrams copy.When this UML code also uses two JS, function library and drawing.First of all, talk about this JS core

Generalization relationship (generalization)The inheritance structure of a class is represented in UML as: generalization (generalize) and implementation (realize):The relationship of the inheritance relationship is is-a, and if the two objects can be represented by is-a, it is an inheritance relationship: (.. Be ...)Eg: Bicycles are cars, cats are animalsA direct representation of a generalized relationship with a hollow arrow, as indicated (a inheri
