SAP R/3 provides a huge number of parametric customizations in order to adapt the system to each particular organization context, and usually consultants, or consulting firms are hired to provide the needed expertise in such reengineering process. Such process is known as Customizing by SAP AG (2003) and J.A. Hernandez (2000). SAP Best Practices by J.A. Hernandez (2000) and R/3 Simplification Group (2003) aims at reusing results obtained using the customized implementations. Central to the best practices approach is the Building Block (BB) concept by R/3 Simplification Group (2003). The basic idea is the modularization of a vertical solution identifying and extracting all its client independent information. BB contents in SAP Best Practices are defined considering from the start the possibility of their reuse from an implementation point of view. Basically, the BB content is defined by the identification of which business process (BP) parts can be reused within a predefined solution. Due to the rapid growth of the BBs number, choosing the correct BB in order to satisfy part of a specific business process, is expensive in terms of time, as the selection is driven only by the developer experience. We present here a toolkit, which allows to model - using semantic annotation - BB descriptions and BPs, and, more important, performs automated selection and composition of BPs. Our framework adopts a subset of OWL-DL as ontology language and description logics (DLs) by F. Baader et al. (2002) as formal framework. Going beyond standard inferences usually provided by DLs, we use in our approach recently defined non standard inferences
SAP R/3提供了大量的参数化定制，以便使系统适应每个特定的组织环境，通常聘请顾问或咨询公司在这种重新设计过程中提供所需的专门知识。这种过程被SAP AG(2003)和J.A. Hernandez(2000)称为定制。J.A. Hernandez(2000)和R/3简化小组(2003)的SAP最佳实践旨在重用使用定制实现获得的结果。最佳实践方法的核心是R/3简化小组(2003)提出的构建块(BB)概念。其基本思想是垂直解决方案的模块化，识别和提取所有与客户端无关的信息。SAP最佳实践中的BB内容从一开始就从实现的角度考虑了重用的可能性。基本上，BB内容是通过识别哪些业务流程(BP)部分可以在预定义的解决方案中重用来定义的。由于BB数量的快速增长，为了满足特定业务流程的一部分，选择正确的BB在时间上是昂贵的，因为选择仅由开发人员的经验驱动。我们在这里提供了一个工具包，它允许使用语义注释对BB描述和bp进行建模，更重要的是，执行bp的自动选择和组合。我们的框架采用OWL-DL的一个子集作为本体语言，采用F. Baader等人(2002)的描述逻辑(dl)作为正式框架。超越了dl通常提供的标准推理，我们在我们的方法中使用了最近定义的非标准推理

This paper describes our experiences of applying dynamic analysis solutions on an industrial legacy application written in C, with the help of aspect orientation (AO). We use a number of dynamic analysis techniques that can help in alleviating the problem of (1) establishing the quality of the available regression test and (2) regaining lost knowledge of the application. We also show why our aspect language for C, aspicere, is well-suited for using dynamic analysis in legacy environments. Finally, we present the case study itself the results we have obtained and the validation thereof by the original developers and current maintainers of the application. We also mention some typical pitfalls that we encountered while dealing with legacy applications in a reengineering context

Database reengineering consists in deriving a new database from a legacy database and adapting associated software components accordingly. This migration process typically involves three main steps, namely schema conversion, data conversion and program conversion. This paper presents a wrapper-based approach to automating the program conversion step. The proposed approach combines program transformations and code generation, which are derived from schema transformations

Migration of form based legacy systems towards service-oriented computing is a challenging task, requiring the adaptation of the legacy interface to the interaction paradigm of Web services. In this paper, a wrapping methodology is proposed to make interactive functionalities of legacy systems accessible as Web services. The wrapper that is used for interacting with the legacy system acts as an interpreter of a finite state automaton that describes the model of the interaction between user and legacy system. This model is obtained by black box reverse engineering techniques. A migration process and a software architecture that allow a functionality of a legacy system to be exported as a Web service are presented in the paper

It is observed that most object oriented coupling metrics are macroscopic, which makes them unsuitable for making finer refactoring decisions. The notions of microscopic viewpoints and coupling projections are introduced. Existing metrics are classified in terms of viewpoints and projections. Two microscopic metrics called relative method coupling (RMC) and relative inward coupling (RIC) are introduced, and a method of applying them to refactoring is discussed. A case study is also included

Softwarenaut is a tool used for the top-down exploration of large software systems. Using it, the reverse engineer can obtain various architectural views of a system by interactively navigating a hierarchical decomposition of the system. In order to accommodate many possible decompositions of a system Softwarenaut was designed as a framework which provides visualization and exploration services that can be applied on various hierarchical decompositions of the system

The high cost of software maintenance could potentially be greatly reduced by the automatic refactoring of object-oriented programs to increase their understandability, adaptability and extensibility. This paper describes a novel approach in providing automated refactoring support for software maintenance; the formulation of the task as a search problem in the space of alternative designs. Such a search is guided by a quality evaluation function that must accurately reflect refactoring goals. We have constructed a search-based software maintenance tool and report here the results of experimental refactoring of two Java programs, which yielded improvements in terms of the quality functions used. We also discuss the comparative merits of the three quality functions employed and the actual effect on program design that resulted from their use

An effective way of leveraging the value of legacy systems is to expose their functionality, or subsets of it, as services. In the business world, this has become a very popular approach because it allows underlying systems to remain largely unchanged, while exposing functionality to a larger number of clients through well-defined service interfaces. The U.S. Department of Defense (DoD) is also adopting this approach by defining service-oriented architectures (SOAs) that include a set of infrastructure common services on which organizations can build additional domain services or applications. When legacy systems or components are to be used as the foundation for domain services, there must be an analysis of how to convert the functionality in existing systems into services. This analysis should consider the specific interactions that is required by the SOA and any changes that need to be made to the legacy components. We have recently helped an organization evaluate the potential for converting components of an existing system into services that would run in a new and tightly constrained DoD SOA environment. This paper describes the process that was used and outlines several issues that need to be addressed in making similar migrations

Versioning systems such as CVS exhibit a large potential to investigate and understand the evolution of large software systems. Bug reporting systems such as Bugzilla help to understand which parts of the system are affected by problems. In this article, we present a novel visual approach to uncover the relationship between evolving software and the way it is affected by software bugs. By visually putting the two aspects close to each other, we can characterize the evolution of software artifacts. We validate our approach on 3 very large open source software systems
