Architectural Style
An architectural style defines as a family of such systems in terms of a pattern of structural organization. More specifically，an architectural style defines a vocabulary of components and connector types，and a set of constraints on how they can be combined. For many styles there may also exist one or more semantic models that specify how to determine a system’s overall properties from the properties of its parts. Many of architectural styles have been developed over the years. The best-known examples of pipe-and-filter architectures are programs written in the UNIX shell.
Note
一种架构风格以一种结构化组织模式定义一组这样的系统。具体来说，一种架构风格定义了一个构件及连接器类型的词汇表，以及一组关于它们如何能够被关联的约束。对于许多风格来说，可能也存在一个或多个语义模型，从系统部件的特性来确定系统的整体特性。许多架构风格已经发展 了很多年，众所周知的管道-过滤器架构就是用 UNIX shell 编写的程序
Software Architecture Reconstruction
Software architecture reconstruction is an interpretive, interactive, and iterative process including many activities. Information extraction involves analyzing a system’s existing design and implementation artifacts to construct a model of it. The result is used in the following activities to construct a view of the system. The database construction activity converts the elements and relations contained in the view into a standard format for storage in a database. The view fusion activity involves defining and manipulating the information stored in database to reconcile, augment, and establish connections between the elements. Reconstruction consists of two primary activities: visualization and interaction, pattern definition and recognition. The former provides a mechanism for the user to manipulate architectural elements, and the latter provides facilities for architecture reconstruction.
Note
软件架构重用是一个解释性、交互式和反复迭代的过程，包括了多项活动。信息提取通过分析系统现有设计和实现工件来构造它的模型。其结果用于在后续活动中构造系统的视图。数据库构建活动把视图中包含的元素和关系转换为数据库中的标准存储格式。视图融合活动包括定义和操作数据库中存储的信息，理顺、加强并建立起元素之间的连接。重构由两个主要活动组成：可视化和交互式及模式定义与识别。前者提供了一种让用户操作架构元素的机制，后者则提供了用于架构重构的设施
