I want to learn about Design Patterns and everywhere I see diagrams like this: Is it UML or something else? I just need a quick reference to learn what do each of different lines mean? which one is inheritance, etc.. 1 Yes it is UML. You can read more (with examples) about class diagrams and other UML diagrams e.g. at http://www.uml-diagrams.org/class-diagrams-overview.html 2 Although it is possible to Google out and print and pin up on your notice board some " UML cheat sheet " or " UML quick reference card " (e.g. http://www.holub.com/goodies/uml ). 3 it is much better to first read a good

一、什么是业务领域建模 领域建模： 从领域模型开始,我们就开始了面向对象的分析和设计过程,可以说,领域模型是完成从需求分析到面向对象设计的一座桥梁。 顾名思义,就是显示最重要的业务概念和它们之间关系，是真实世界各个事物的表示（现实世界的可视化抽象字典）而不是软件中各构件的表示。领域模型是描述业务领域（业务实体）的静态结构。 理论派观点： Domain Model是一个商业建模范畴概念，即使一个企业不开发软件，也具备其业务模型； 所有同行企业，其业务模型必定有非常大的共性和内在的规律性。 由行业内的各个企业的业务模型再向上抽象出整个行业的业务模型，这个模型称之为“领域模型”。 领域模型是一种特殊的业务模型，它分析范围是整个行业，抽象出行业里共性和内在规律性的业务，比业务模型更加抽象，它不属于软件开发范畴的概念，与软件开发无关。 实战派观点： 领域模型是一个分析模型，帮助系统分析人员、用户认识现实业务的工具，描述的是业务中涉及到的实体及其相互之间的关系，它是需求分析的产物，与问题域相关。 是需求分析人员与用户交流的有力工具，是彼此交流的语言。 领域模型是一种分析模型，在软件开发过程分析阶段用于分析如何满足系统功能性需求，属于软件开发范畴，在UML中主要使用类图来描述领域模型。 业务模型是业务建模的输出物，业务建模研究的对象是公司或者组织，业务建模属于软件开发过程中的初始阶段。

I have been searching for some material that describes how to generate simple class diagrams with doxygen, but couldn't find one. Can anybody help? I need to create diagrams as shown below from a set of C++ files. If there are better tools to achieve this easier, please let me know. DPD Doxygen creates inheritance diagrams but I dont think it will create an entire class hierachy. It does allow you to use the GraphViz tool. If you use the Doxygen GUI frontend tool you will find the relevant options in Step2: -> Wizard tab -> Diagrams . The DOT relation options are under the Expert Tab. average

Is there a tool that can parse C++ files within a project and generate UML from it? jwpfox Here are a few options: Step-by-Step Guide to Reverse Engineering Code into UML Diagrams with Microsoft Visio 2000 - http://msdn.microsoft.com/en-us/library/aa140255(office.10).aspx BoUML - http://bouml.fr/features.html StarUML - http://staruml.sourceforge.net/en/ Reverse engineering of the UML class diagram from C++ code in presence of weakly typed containers (2001) - http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.27.9064 Umbrello UML Modeller - http://uml.sourceforge.net/ A list of other tools

Which UML diagram is the best for showing dependency between our IT system and other external IT systems? For example I would like to show on diagram: system A gets data from system B system B can call some functionality from system A I'm wondering between component diagram and sequence diagram. What do you think? Components definitelly, and dependencies. Dependency does not go in direction of the data-flow, but from the component that "knows" other component (invokes something from it, creates an object, etc). The following diagram shows the idea. It is common (and highly recommendable)

In college I've had numerous design and UML oriented courses, and I recognize that UML can be used to benefit a software project, especially use-case mapping, but is it really practical? I've done a few co-op work terms, and it appears that UML is not used heavily in the industry. Is it worth the time during a project to create UML diagrams? Also, I find that class diagrams are generally not useful, because it's just faster to look at the header file for a class. Specifically which diagrams are the most useful? Edit: My experience is limited to small, under 10 developer projects. Edit: Many
