Open Source Systems

Open source software systems have poor or inexistent documentation and contributors are often scattered or missing. The reuse-based composition and maintenance of open source software systems therefore implies that program comprehension becomes a critical activity if all the embedded behavior is to be preserved. Program comprehension has traditionally been addressed by reverse engineering techniques which retrieve system design models such as class diagrams. These abstract representations provide a key artifact during migration or evolution. However, this method may retrieve large complex class diagrams which do not ensure a suitable program comprehension. This chapter attempts to improve program comprehension by providing a model-driven reverse engineering technique with which to obtain business processes models that can be used in combination with system design models such as class diagrams. The advantage of this approach is that business processes provide a simple system viewpoint at a higher abstraction level and filter out particular technical details related to source code. The technique is fully developed and tool-supported within an R&D project about global software development in which collaborate two universities and five companies. The automation of the approach facilitates its validation and transference through an industrial case study involving two open source systems.

Business To Business

One of the vital reasons for reverse engineering legacy software systems is to make it inter-operable. Moreover, technological advancements and changes in usability also motivate reverse engineering to exploit new features and incorporate them in legacy software systems. In this context, Web services are emerging and evolving as solutions for software systems for business applications in terms of facilitating interactions between business to business and business to customers. Web services are gaining significance due to inherent features like interoperability, simple implementation, and exploiting the boom in Internet infrastructure. Thus, this work proposes a framework based strategy using .net for effortless migration from legacy software systems to Web services. Further, this work also proposes that software metrics observed during the process of reverse engineering facilitate design of Web services from legacy systems.

Programming Quality

BackgroundPortable-devices applications (Android applications) are becoming complex software systems that must be developed quickly and continuously evolved to fit new user requirements and execution contexts. Applications must be produced rapidly and advance persistently in order to fit new client requirements and execution settings. However, catering to these imperatives may bring about poor outline decisions on design choices, known as anti-patterns, which may possibly corrupt programming quality and execution. Thus, the automatic detection of anti-patterns is a vital process that facilitates both maintenance and evolution tasks. Additionally, it guides developers to refactor their applications and consequently enhance their quality.MethodsWe proposed a general method to detect mobile applications’ anti-patterns that can detect both semantic and structural design anti-patterns. The proposed method is via reverse-engineering and ontology by using a UML modeling environment, an OWL ontology-based platform and ontology-driven conceptual modeling. We present and test a new method that generates the OWL ontology of mobile applications and analyzes the relationships among object-oriented anti-patterns and offer methods to resolve the anti-patterns by detecting and treating 15 different design’s semantic and structural anti-patterns that occurred in analyzing of 29 mobile applications. We choose 29 mobile applications randomly. Selecting a browser is not a criterion in this method because the proposed method is applied on a design level. We demonstrate a semantic integration method to reduce the incidence of anti-patterns using the ontology merging on mobile applications.ResultsThe proposed method detected 15 semantic and structural design anti-patterns which have appeared 1,262 times in a random sample of 29 mobile applications. The proposed method introduced a new classification of the anti-patterns divided into four groups. “The anti-patterns in the class group” is the most group that has the maximum occurrences of anti-patterns and “The anti-patterns in the operation group” is the smallest one that has the minimum occurrences of the anti-patterns which are detected by the proposed method. The results also showed the correlation between the selected tools which we used as Modelio, the Protégé platform, and the OLED editor of the OntoUML. The results showed that there was a high positive relation between Modelio and Protégé which implies that the combination between both increases the accuracy level of the detection of anti-patterns. In the evaluation and analyzing the suitable integration method, we applied the different methods on homogeneous mobile applications and found that using ontology increased the detection percentage approximately by 11.3% in addition to guaranteed consistency.

Architectural Representation

Recently, reverse engineering (RE) is becoming one of the essential engineering trends for software evolution and maintenance. RE is used to support the process of analyzing and recapturing the design information in legacy systems or complex systems during the maintenance phase. The major problem stakeholders might face in understanding the architecture of existing software systems is that the knowledge of software architecture information is difficult to obtain because of the size of the system, and the existing architecture document often is missing or does not match the current implementation of the source code. Therefore, much more effort and time are needed from multiple stakeholders such as developers, maintainers and architects for obtaining and re-documenting and visualizing the architecture of a target system from its source code files. The current works is mainly focused on the developer viewpoint. In this paper, we present a RE methodology for visualizing architectural information for multiple stakeholders and viewpoints based on applying the RE process on specific parts of the source code. The process is driven by eliciting stakeholders’ concerns on specific architectural viewpoints to obtain and visualize architectural information related these concerns. Our contributions are three fold: 1- The RE methodology is based on the IEEE 1471 standard for architectural description and supports concerns of stakeholder including the end-user and maintainer; 2- It supports the visualization of a particular part of the target system by providing a visual model of the architectural representation which highlights the main components needed to execute specific functionality of the target system, 3- The methodology also uses architecture styles to organize the visual architecture information. We illustrate the methodology using a case study of a legacy web application system.

Compiler Techniques

Reverse engineering is the process of analyzing software systems to extract software artifacts at a higher level of abstraction so that it is easier to understand them, e.g., for reengineering, modernizing, reuse, migration or documenting purposes. This chapter describes an approach to reverse engineering object oriented code. A central idea in reverse engineering is exploiting the source code as the most reliable description both of the system behavior and of the organization and its business rules. We propose an approach for MDA-based object oriented reverse engineering that integrates classical compiler techniques, metamodeling techniques and formal specification for recovering designs and architectures. We analyze reverse engineering of PSMs and PIMs from object-oriented code. Models are expressed using UML and OCL. On the one hand, the subset of UML diagrams, that are useful for platform-dependent models, includes class diagram, object diagram, state diagram, interaction diagram (collaboration diagram and sequence diagram) and package diagram. On the other hand, a PIM can be expressed by means of use case diagrams, activity diagrams, interaction diagrams to model system processes and state diagrams to model lifecycle of the system entities.
