 The Rational Unified Process (RUP) is a software engineering process, which captures many of best practices in modern software development. The notices of use-cases and scenarios have been proven to be an excellent way to capture function requirements. RUP can be described in two dimensions – time and content. In the time dimension, the software lifecycle is broken into cycles. Each cycle is divided into four consecutive phases which is concluded with a well-defined milestone and can be further broken down into iterations – a complete development loop resulting in a release of an executable product a subset of the final product under development, which grows incrementally to become the final system. The content structure refers to the disciplines, which group activities logically by name.

RUP (The Rational Unified Process)是一种软件工程过程产品，它吸取了现代软件开发中许多成功的实践。事实证明，采用用例（use-cases）和剧情（scenarios）捕获目标系统的功能需求是一种较好的办法。可以采用二维模型来描述RUP-------时间和内容。从时间维来看，软件生存周期被划分为不同的周期（cycles）。每个周期又被划分为4个连续的阶段（phases），每个阶段都包含一个妥善定义的里程碑（iterations）；每个阶段还可以被进一步划分为若干轮迭代（iterations）。一次迭代是一次完整的开发过程，每次迭代结束时会发布一个可执行的产品，这个产品，这个产品是正在开发的软件系统的一个子集，它会逐渐扩展为最终系统。内容结构指的是一些将活动（activities）组织在一起的、天然存在的规则。

 

Model-driven analysis emphasizes the drawing of pictorial system models to document and validate both existing and/or proposed systems. Ultimately, the system models become the blueprint for designing and constructing an improved system. Structured analysis is such a technique. The emphasis in this technique is process – centered. Systems analysts draw a series of process models called DFD. Information engineering is another such technique that integrates data and process concerns into constructs called objects.

 模型驱动的分析方法强调通过绘制图形化的系统模型来说明和验证已有的或待开发的系统。这些系统模型最终会成为设计和构建改进后的系统的蓝图。结构分析就是这样一种方法，这是以过程为中心的。在结构化分析员所绘制的一系列过程模型被称为DFD。面向对象分析是另外一种模型驱动的分析方法，它将数据和过程统一到了一个被称为“对象”的结构中。

 

Virtualization is an approach to IT that pools and shares resources so that utilization is optimized and supplies automatically meet demand. Traditional IT environments are often silos, where both technology and human resources are aligned an application or business function. With a virtualized infrastructure, people, processes, and technology are focused on meeting service levels capacity is allocated dynamically, resources are optimized, and the entire infrastructure is simplified and flexible. We offer a broad spectrum of virtualization solutions that allows customers to choose the most appropriate path and optimization focus for their IT infrastructure resources.

虚拟化是IT行业缓存和共享资源的一种方法，通过这种方法可以更好地利用资源，并且自动提供资源以满足需求。传统的IT环境通常是一个坚井，技术和人力资源都是围绕应用或商业功能来安排的。利用虚拟化的架构，人员、过程和技术都集中于满足服务的过程，生产量被动态地分配，资源得到优化，而且整个架构得以简化，变得很灵活。我们提供了广泛的虚拟化解决方案，允许客户为他们的IT资源的基础架构选择最适用的路线和优化的重点。
