Enterprise Architect 8 > Displaying Inheritance Chain for a Class

和自甴很熟 提交于 2019-12-06 13:01:03
问题 I have imported a PHP source folder into Enterprise Architect. Now, I'd like to see the inheritance chain of any specific class. In other words, I'd like to see one big diagram displaying all relations of a class. Most classes are in folders separate from the parent/child class. How can I do that..? This was my reason for installing Enterprise Architect: I get confused within a lengthy and branched inheritance chain. It would be very disappointing if such a powerful tool that recognizes all

Designing a sequence diagram for an auction system

元气小坏坏 提交于 2019-12-06 12:28:58
问题 I'm currently working on a sequence diagram for an auction system which acts as the middleman between customers and companies. However I'm having difficulty with the design of the system and would appreciate some guidance, especially as I seek to tighten up the UML diagram. The entire idea behind the system is that the customer creates a booking via a mobile app which uploaded to the auction app where companies can bid for it. If a company wins a bid, the auction app gives them a price range

Transitions in UML state charts: better to use triggers or guards?

落爺英雄遲暮 提交于 2019-12-06 11:48:19
In the design of UML state charts it appears that I can chose to use either triggers or guard logic to achieve transitions between states. So which is better to use? Given the same logic for transition, does a trigger behave any differently than a guard? What are the benefits/drawbacks of one over the other? Are there perhaps differences depending on the particular tool, or does the UML standard strictly define the behaviors of either method of transition? I'm presently using Simulink Stateflow to design a state machine. Those two are different concepts. Trigger is an event occurrence which

What is the difference between sequence diagrams and communication (collaboration) diagrams in UML? 回答1: Quoting Wikipedia: Communication diagrams show a lot of the same information as sequence diagrams, but because of how the information is presented, some of it is easier to find

UML各种图总结-精华 https://www.cnblogs.com/jiangds/p/6596595.html UML(Unified Modeling Language)是一种统一建模语言,为面向对象开发系统的产品进行说明、可视化、和编制文档的一种标准语言。下面将对UML的九种图+包图的基本概念进行介绍以及各个图的使用场景。 想要知道UML更多内容的朋友,可以点击以下课程学习相关知识:    https://edu.csdn.net/course/play/24752/280547 一、基本概念     如下图所示,UML图分为用例视图、设计视图、进程视图、实现视图和拓扑视图,又可以静动分为静态视图和动态视图。静态图分为:用例图,类图,对象图,包图,构件图,部署图。动态图分为:状态图,活动图,协作图,序列图。    1、用例图(UseCase Diagrams):   用例图主要回答了两个问题:1、是谁用软件。2、软件的功能。从用户的角度描述了系统的功能,并指出各个功能的执行者,强调用户的使用者,系统为执行者完成哪些功能。    2、类图(Class Diagrams):      用户根据用例图抽象成类,描述类的内部结构和类与类之间的关系,是一种静态结构图。 在UML类图中,常见的有以下几种关系: 泛化(Generalization), 实现(Realization)

How to represent Listeners in UML sequence diagram

有些话、适合烂在心里 提交于 2019-12-06 09:37:13
In sequence diagrams, how would you represent an event triggered listener? It is not just a regular method call, so displaying like that would not seem correct. I try to make a sequence diagram of a system including a JMS listener. I could start the lifeline with the send() call of the system to the JMS queue (displaying the system calling send() as a business actor), or I could start the lifeline at the onMessage() call. (displaying JMS Queue as a business actor) Or should I just ignore the whole JMS Queue in the diagram? For what it's worth: I'm using Astah Community to create the diagrams.

目录 1、啥是UML类图? 2、UML类图有啥用? 3、正式理解UML类图 4、使用idea画第一个UML类图 5、类之间的关系图【必须牢记】 6、类之间的关系 6.1、依赖 6.2、泛化 6.3、实现 6.4、关联 6.5、聚合 6.6、组合 7、简单总结类之间的六种关系 前言 关于UML类图的这篇文章,我觉得把它放在设计模式专栏的篇首最为合适,因为在学习设计模式的时候,经常会遇到有关UML类图,没有去专门学过的童鞋肯定会感觉很复杂。学到后面,发现不掌握UML类图,对设计模式或者某一个框架没有整体的把控。所以学好UML类图,你将会更加有自信! 如果你对类之间的依赖、聚合、关联、组合等关系还很抵制的话,那么这篇文章就很有必要看了,随着对设计模式的慢慢深入了解,或许你也会发现,UML类图就显得格外重要了,是的,UML类图主要是用来描述类之间的轮廓图,而类之间的常见关系就是泛化(Generalization)、实现(Realization)、依赖(Dependence)、关联(Association)、聚合(Aggregation)、组合(Composition)等。类之间关系的强弱:依赖 < 关联 < 聚合 < 组合 < 泛化(继承) @ 1、啥是UML类图? 首先来看一个专业一点的定义【来自维基百科】 UML即 统一建模语言 (Unified Modeling Language)

Relationships in a UML class diagram

。_饼干妹妹 提交于 2019-12-06 08:33:53
问题 I have an application that models a tree, with classes Tree, Node and Edge (I need the Edge class!), and I'm not sure how to represent the relationships in the class diagram for this. I've read other posts about this, but am still in doubt. The Tree object have a pointer to a Node (its root), which I believe defines an one-way association (Tree -> Node) with multiplicity 1..1 in both ends. Is it right? Each Node object have pointers to the edges that comes out of it (Edge objects). Since
