Using a Single Business Pattern with the RUP -part1

Rational Unified Process (RUP) 是一种商业软件开发流程框架,提供了一种规范化的软件开发方法。其核心目标是在可预测的时间和预算内交付高质量、满足最终用户需求的软件。RUP 通过迭代开发、需求管理、组件架构、视觉建模和质量持续验证等最佳实践来实现这一目标。

The Rational® Unified Process® (RUP®) is a commercial software development
process framework. The RUP is composed of:
- Best practices. The RUP includes a library of best practices for software
engineering, covering everything from project management to detailed test
guidance.
- Process delivery tools. The RUP is delivered using Web technology, allowing
it be integrated with other software development tools and making it easily
accessible to developers.
- Configuration tools. The RUP is made up of components and plug-ins that
can be selected and configured to meet the needs of different kinds of
projects.
- Process authoring tools. An organization can extend or modify the RUP by
creating its own plug-ins using the Rational Process Workbench® product.
- Community/marketplace. The Rational Developer Network® (RDN™)
provides a place for process engineers in the software development
community to share their process extensions.

Software development best practices

The RUP is a software development process framework that provides a
disciplined approach to software development. Its goal is to ensure the
production of high-quality software that meets the needs of its end users within a
predictable schedule and budget.
Central to meeting this goal is promoting commercially proven “best practices.”
These best practices include:
- Develop iteratively.
- Manage requirements.
- Use component-based architectures.
- Visually model software.
- Continuously verify software quality.
- Control changes to software.

Develop iteratively
System functionality should be delivered in a successive series of releases,
addressing critical risks and getting feedback in the early releases.
Manage requirements
Requirements management is a systematic approach to eliciting, organizing,
communicating, and managing the changing requirements of a
software-intensive system or application.
Effective requirements management enables better control over customer
satisfaction, budget, and schedule.
Use component-based architecture
The Rational Unified Process provides a methodical, systematic way to design,
develop, and validate an architecture. Architectures based on components are
more flexible, reusable, and understandable than architectures based on other
approaches.
Visually model software
Models are simplifications of reality; they help us to understand and shape both a
problem and its solution and to comprehend large, complex systems that we
could not otherwise understand as a whole. RUP uses the Unified Modeling
Language (UML), a standard graphical language for visualizing, specifying,
constructing, and documenting software-intensive systems.
Continuously verify quality
Quality is the responsibility of every member of the development organization; it
isn’t added by specialized staff at the end of the project. Quality is managed
throughout the life cycle by implementing and assessing both process quality and
product quality.

内容概要:本文详细介绍了C语言指针和字符串操作的基础知识与高级技巧。指针部分涵盖了指针作为数据类型的特点,包括指针变量的定义、间接赋值的应用场景及其重要性,以及不同级别的指针如何在函数间传递并修改实参的值。同时强调了指针操作的安全性问题,如不允许向NULL或未知地址拷贝内存,并讲解了`void*`指针的作用及其转换规则。字符串操作部分则重点讨论了字符串初始化、`sizeof`与`strlen`的区别、字符`\0`的作用及其与其他符号的区别,还展示了数组法和指针法两种操作字符串的方式,并给出了几个常见的字符串处理算法实例,如统计子串出现次数、去除字符串两端空白字符等。 适用人群:具有初步C语言基础的学习者,特别是对指针和字符串操作有进一步需求的编程人员。 使用场景及目标:①帮助读者深入理解指针的工作机制,掌握通过指针间接访问和修改内存的技术;②使读者能够熟练运用字符串操作的基本函数,并能编写高效的字符串处理代码;③培养读者的安全意识,避免因不当使用指针而导致程序崩溃或产生未定义行为。 阅读建议:由于指针和字符串是C语言中较为复杂的概念,建议读者在学习过程中多做笔记,动手实践书中的示例代码,尤其要注意理解指针间接赋值的原理,以及字符串处理函数的具体实现细节。此外,对于`void*`指针的理解和使用,应特别留意其类型转换的要求,确保代码的安全性和正确性。
