课程名称：软件设计作为一种抽象 课程概述：软件开发过程中的设计步骤具有独特的特点。首先，这个步骤是唯一一个绘制图形的常态化环节。那么，为什么会这样？图形能提供什么其他表现形式无法提供的信息？图形具有不同的细节层次，有其上下文，这些特点让图形能够“描绘出一幅画”。这些要素为何重要？在本课程中，我们也将从其他学科（如建筑设计）中寻找设计的启示。 课程大纲： 1. 谁需要抽象？ - 描述：将设计视为软件开发过程中的一个步骤，探讨设计作为项目的抽象表现形式。 2. 聚焦用户 - 描述：强调在考虑用户参与的情况下的设计考量。 3. 如果没有用户呢？ - 描述：探讨在没有用户参与时应考虑的设计要素。 4. 高级数据库设计 - 描述：何时应创建第三正常形式的数据库，以及何时不该这样做。 5. 设计模式的优缺点 - 描述：讨论设计模式何时有用，何时无用。 6. 语言选择 - 描述：恰当选择语言和操作系统，因为你需要长期使用它们。 7. 期末考试 - 描述：课程的综合评估，包括5个测验，每个测验由不同模块的随机问题组成。 本课程旨在帮助学员理解软件设计的抽象性，多角度的思考用户需求，并掌握相关的数据库设计与编程语言选择。
Name:Who needs abstractions?
Description:Contrasted to design as a step in the software development process, a look at design as an abstract representation of the project.
Name:Focus on the Users
Description:Design considerations to make when users are involved.
Name:What if there are no users?
Description:Design considerations to make when users are not involved
Name:Advanced database design
Description:When to create a database in third-normal form, and when not to.
Name:The Good and Bad of Design Patterns
Description:When and how design patterns are useful and when they are not.
Name:Language choices
Description:Choose languages and operating systems wisely because you will have to live with them.
Name:Final Exam
Description:A comprehensive course assessment comprising of 5 quizzes. Each assessment contains a randomized set of questions from different modules of the course.
The design step in developing software has some unique characteristics. First of all, it’s the only step where drawing pictures of things is the norm. Why is that? What do pictures do that other representations cannot do? Pictures have varying levels of detail; pictures have context. Pictures…paint a picture. Why are these things important? In this course, too, we begin looking at other disciplines (building architecture is a favorite one) for lessons on design.
