Analysis of Software Binaries for Reengineering-Driven Product Line Architecture\^aAn Industrial Case Study

This paper describes a method for the recovering of software architectures from a set of similar (but unrelated) software products in binary form. One intention is to drive refactoring into software product lines and combine architecture recovery with run time binary analysis and existing clustering methods. Using our runtime binary analysis, we create graphs that capture the dependencies between different software parts. These are clustered into smaller component graphs, that group software parts with high interactions into larger entities. The component graphs serve as a basis for further software product line work. In this paper, we concentrate on the analysis part of the method and the graph clustering. We apply the graph clustering method to a real application in the context of automation / robot configuration software tools.Comment: In Proceedings FMSPLE 2015, arXiv:1504.0301

Mediated data integration and transformation for web service-based software architectures

Service-oriented architecture using XML-based web services has been widely accepted by many organisations as the standard infrastructure to integrate heterogeneous and autonomous data sources. As a result, many Web service providers are built up on top of the data sources to share the data by supporting provided and required interfaces and methods of data access in a unified manner. In the context of data integration, problems arise when Web services are assembled to deliver an integrated view of data, adaptable to the specific needs of individual clients and providers. Traditional approaches of data integration and transformation are not suitable to automate the construction of connectors dedicated to connect selected Web services to render integrated and tailored views of data. We propose a declarative approach that addresses the oftenneglected data integration and adaptivity aspects of serviceoriented architecture

Search based software engineering: Trends, techniques and applications

© ACM, 2012. This is the author's version of the work. It is posted here by permission of ACM for your personal use. Not for redistribution. The definitive version is available from the link below.In the past five years there has been a dramatic increase in work on Search-Based Software Engineering (SBSE), an approach to Software Engineering (SE) in which Search-Based Optimization (SBO) algorithms are used to address problems in SE. SBSE has been applied to problems throughout the SE lifecycle, from requirements and project planning to maintenance and reengineering. The approach is attractive because it offers a suite of adaptive automated and semiautomated solutions in situations typified by large complex problem spaces with multiple competing and conflicting objectives. This article provides a review and classification of literature on SBSE. The work identifies research trends and relationships between the techniques applied and the applications to which they have been applied and highlights gaps in the literature and avenues for further research.EPSRC and E

Science & engineering software migration: moving from desktop to mobile applications

The proliferation of mobile devices over the last years provides opportunities and challenges for solving problems in Science & Engineering. Among other novel features, mobile devices contain global positioning sensors, wireless connectivity, built-in web browsers and photo/video/voice capabilities that allow providing highly localized, context aware applications. Mobile phones have become as powerful as any desktop computer in terms of applications they can run. However, the software development in mobile computing is still not as mature as it is for desktop computer and the whole potential of mobile devices is wasted. A current problem in the engineering community is the adaptation of desktop applications for mobile technologies. To take advantage of new platform technologies, existing software must evolve. A number of solutions have been proposed to deal with this problem such as redevelopment, which rewrites existing applications, or migration, which moves the existing system to a more flexible environment while retaining the original system data and functionality. A good solution should be to restore the value of the existing software, extracting knowledge and exploiting investment in order to migrate to new software that incorporates the new technologies. On the one hand, traditional reverse engineering techniques can help in the software migration to mobile applications. They are related to the process of analyzing available software with the objective of extracting information and providing high-level views on the underlying code. On the other hand, to achieve interoperability with multiple platforms the migration needs of technical frameworks for information integration and tool interoperability such as the initiative of the Object Management Group (OMG) called Model Driven Architecture (MDA). The outstanding ideas behind MDA are separating the specification of the system functionality from its implementation on specific platforms and managing the software evolution from abstract models to implementations increasing the degree of automation. The objective of this paper is to describe a reengineering process that allow moving existing desktop applications for solving engineering problems of multidisciplinary character to mobile platforms. Our research aims to simplify the creation of applications for mobile platforms by integrating traditional reverse engineering techniques, such static and dynamic analysis, with MDA. We validated our approach by using the open source application platform Eclipse, EMF (Eclipse Modeling Framework), EMP (Eclipse Modeling Project) and the Android platform

RETHINKING THE BUSINESS PROCESS THROUGH REENGINEERING

Rethinking business through reengineering is based on the assumption that to meet contemporary demands of quality, service, flexibility, and low cost, processes must be kept simple. Examples of simplifying processes are combining several jobs into one, letting workers make decisions, performing the steps in a process in a natural order, and performing work where it makes the most sense. The net result is that work may be shifted across functional boundaries several times to expedite its accomplishment. Traditional inspection and control procedures are often eliminated or deferred until the process is complete, providing further cost savings. The authors, focusing their research on enterprises from Oltenia Region, demonstrate how reengineering can be carried out in a variety of corporate settings. But although workers are the ones who need to be empowered to carry out reengineering, the authors are adamant that the process must start at the top. This is because it involves making major changes that are likely to cut across traditional organizational boundaries. Those empowered to make the changes at lower levels must know they have the support of top management, or change won�t occur.reengineering, rethinking business processes, regional economy, leadership, organization

Reverse Engineering of Computer-Based Navy Systems

The financial pressure to meet the need for change in computer-based systems through evolution rather than through revolution has spawned the discipline of reengineering. One driving factor of reengineering is that it is increasingly becoming the case that enhanced requirements placed on computer-based systems are overstressing the processing resources of the systems. Thus, the distribution of processing load over highly parallel and distributed hardware architectures has become part of the reengineering process for computer-based Navy systems. This paper presents an intermediate representation (IR) for capturing features of computer-based systems to enable reengineering for concurrency. A novel feature of the IR is that it incorporates the mission critical software architecture, a view that enables information to be captured at five levels of granularity: the element/program level, the task level, the module/class/package level, the method/procedure level, and the statement/instruction level. An approach to reverse engineering is presented, in which the IR is captured, and is analyzed to identify potential concurrency. Thus, the paper defines concurrency metrics to guide the reengineering tasks of identifying, enhancing, and assessing concurrency, and for performing partitioning and assignment. Concurrency metrics are defined at several tiers of the mission critical software architecture. In addition to contributing an approach to reverse engineering for computer-based systems, the paper also discusses a reverse engineering analysis toolset that constructs and displays the IR and the concurrency metrics for Ada programs. Additionally, the paper contains a discussion of the context of our reengineering efforts within the United States Navy, by describing two reengineering projects focused on sussystems of the AEGIS Weapon System

Business rules based legacy system evolution towards service-oriented architecture.

Enterprises can be empowered to live up to the potential of becoming dynamic, agile and real-time. Service orientation is emerging from the amalgamation of a number of key business, technology and cultural developments. Three essential trends in particular are coming together to create a new revolutionary breed of enterprise, the service-oriented enterprise (SOE): (1) the continuous performance management of the enterprise; (2) the emergence of business process management; and (3) advances in the standards-based service-oriented infrastructures. This thesis focuses on this emerging three-layered architecture that builds on a service-oriented architecture framework, with a process layer that brings technology and business together, and a corporate performance layer that continually monitors and improves the performance indicators of global enterprises provides a novel framework for the business context in which to apply the important technical idea of service orientation and moves it from being an interesting tool for engineers to a vehicle for business managers to fundamentally improve their businesses

Design of Model For Restructure Transformation of Public Sector

Public sector such as Govt. University composed of many physical as well logical threads, which are very beneficial for public to provide services. Over times due to repeated modification of software modules, the structure of the system deteriorates and it become very complex to understand for further modification whenever requirement need to provide services to public, because it is universal truth after specific time period there is need of modification to fulfill the requirement for public. And if we repeat to modify the software module, then it is very complicated just like noodles in chowmin plate and program structure is twisted and tangled. Due to this program structure greatly decrease the scalability, reliability, efficiency, robustness and increased the complexity of software module. And it also increased the maintenance cost of software module, therefore repeated modification is not a good choice. Reengineering is good choice for this. Therefore, in this paper we will introduced a new methodology that is known as pattern based reengineer methodology, that is not only focus on only logical thread, but also focus on physical entities - reduce overall complexity. It is proved that the transformation does not alter the semantic of restructured program
