Recovering Sequence Diagrams from Object-oriented Code

Software modernization is a current research area in the software industry intended to transform an existing software system to a new one satisfying new demands. The initiative Architecture-Driven Modernization (ADM) helps software developers in tackling reverse engineering, software evolution and, software modernization in general. To support modernization problems, the ADM Task Force has defined a set of metamodels such as KDM (Knowledge Discovery Metamodel), being the Eclipse-MDT MoDisco project the official support for software modernization. We propose the application of ADM principles to provide relevant model-based views on legacy systems. We describe a framework to reverse engineering models from object-oriented code. In this context, we show how to recover UML sequence diagrams from Java code. We validate our approach by using ADM standards and MoDisco platform. Our research can be considered a contribution to the MoDisco community; MoDisco does not support reverse engineering of sequence diagrams and, on the other hand, the MoDisco KDM Discover was used and enriched to obtain the required information for recovering interaction diagrams

TRACEM - Towards a Standard Metamodel for Execution Traces in Model-Driven Reverse Engineering

Reverse engineering is a crucial stage in the software modernization process. The current techniques available in existing CASE tools provide forward engineering and limited facilities for reverse engineering, dynamic analysis in particular. The Architecture-Driven Modernization initiative has defined standards to support the modernization process in the model-driven engineering (MDE) context. Standardization increases interoperability between different tools enabling a new generation of solutions to benefit the whole industry and encourage collaboration among complementary vendors. In this paper, we present TRACEM, a metamodel to represent trace information under a standard representation. This metamodel complements a MDE framework for software modernization that aims to integrate static and dynamic analysis techniques during the reverse engineering process. This paper includes a case study that exemplifies how dynamic information combined with static information allows improving the whole reverse engineering process.XIX Workshop Ingeniería de Software (WIS)Red de Universidades con Carreras en Informátic

Migrating C/C++ Software to Mobile Platforms in the ADM Context

Software technology is constantly evolving and therefore the development of applications requires adapting software components and applications in order to be aligned to new paradigms such as Pervasive Computing, Cloud Computing and Internet of Things. In particular, many desktop software components need to be migrated to mobile technologies. This migration faces many challenges due to the proliferation of different mobile platforms. Developers usually make applications tailored for each type of device expending time and effort. As a result, new programming languages are emerging to integrate the native behaviors of the different platforms targeted in development projects. In this direction, the Haxe language allows writing mobile applications that target all major mobile platforms. Novel technical frameworks for information integration and tool interoperability such as Architecture-Driven Modernization (ADM) proposed by the Object Management Group (OMG) can help to manage a huge diversity of mobile technologies. The Architecture-Driven Modernization Task Force (ADMTF) was formed to create specifications and promote industry consensus on the modernization of existing applications. In this work, we propose a migration process from C/C++ software to different mobile platforms that integrates ADM standards with Haxe. We exemplify the different steps of the process with a simple case study, the migration of “the Set of Mandelbrot” C++ application. The proposal was validated in Eclipse Modeling Framework considering that some of its tools and run-time environments are aligned with ADM standards

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

model driven reverse engineering approaches a systematic literature review

This paper explores and describes the state of the art for what concerns the model-driven approaches proposed in the literature to support reverse engineering. We conducted a systematic literature review on this topic with the aim to answer three research questions. We focus on various solutions developed for model-driven reverse engineering, outlining in particular the models they use and the transformations applied to the models. We also consider the tools used for model definition, extraction, and transformation and the level of automation reached by the available tools. The model-driven reverse engineering approaches are also analyzed based on various features such as genericity, extensibility, automation of the reverse engineering process, and coverage of the full or partial source artifacts. We describe in detail and compare fifteen approaches applying model-driven reverse engineering. Based on this analysis, we identify and indicate some hints on choosing a model-driven reverse engineering approach from the available ones, and we outline open issues concerning the model-driven reverse engineering approaches

Extending the Abstract Data Model.

The Abstract Data Model (ADM) was developed by Sanderson [19] to model and predict semantic loss in data translation between computer languages. In this work, the ADM was applied to eight languages that were not considered as part of the original work. Some of the languages were found to support semantic features, such as the restriction semantics for inheritance found in languages like XML Schemas and Java, which could not be represented in the ADM. A proposal was made to extend the ADM to support these semantic features, and the requirements and implications of implementing that proposal were considered
