有许多用C和Java等较新的语言编写的大型关键业务软件系统正在迅速成为遗留问题，并且越来越难以维护。与旧的单体系统不同，在旧的单体系统中，模块化主要涉及将单体代码库拆分为模块，对于这些已经具有一些基本模块化结构的新系统，代码分解只是许多可能的活动之一。尽管软件模块化领域在过去的几年中受到了相当大的关注，但是关于大型C和Java系统模块化的文献中几乎没有记录任何案例研究。当有经验的开发人员必须模块化这样的新系统时，我们仍然不能完全理解他们所执行的活动。本文的目标是从过去的软件模块化项目中学习，并确定常见的重复模式。本文形式化了6种这样的模式，我们称之为模块化操作符，它们可能是任何软件模块化活动的基本构建块。本文使用开源软件系统和专有软件系统的模块化案例研究验证了操作符，并提出了一些观察和见解。
There exists a number of large business critical software systems written in newer languages such as C and Java that are fast becoming legacy and increasingly difficult to maintain. Unlike older monolithic systems, where modularization primarily involves splitting the monolithic code base into modules, for such newer systems which already have some basic modular structure, code decomposition is only one of the many possible activities. Even though the area of software modularization has received considerable attention over these past years, there are hardly any case studies documented in literature on modularizing large C and Java systems. We still do not fully comprehend the activities experienced developers perform when they have to modularize such newer systems. The goal of this paper is to learn from past software modularization projects and identify common recurring patterns. This paper formalizes 6 such patterns, which we term as modularization operators, that are likely to be the basic building blocks of any software modularization activity. The operators presented in this paper are validated using modularization case studies of open source software systems and a proprietary software system and several observations and insights are presented.
