In this paper, we present a exception-flow analysis tool, called eFlow Mining, that automates the process of gathering and visualizing exception-handling constructs in multi-programming languages. More specifically, the current version of eFlow Mining focuses on code written using the .NET framework to help developers in inspecting applications either to improve them or to understand their exception...
To complete successfully system shortest path programming (SSPP) visualization research process, oriental systems methodology (OSM) had been introduced in the development process and had been achieved good results. It had been combined with system shortest path programming visualization device structure model, applied to “knowing Wuli, sensing Shili, caring for Renli” as the guiding ideology, and...
Virtualization of embedded systems has recently been in the spotlight especially because of the numerous advantages it can bring. Among these, the improvement of software design quality can be highlighted, since legacy software can be reused along with newer applications, easing newer and older systems' integration. Also, security concerned systems can enjoy the gains of virtualization: two Operating...
Traditional software metrics have the limitations for large-scale software system, so we construct the static structure model for large-scale software by structural mapping and visualization, propose a integrated metrics set based on complex networks parameters according to the perspective of software engineering. The feasibility and validity of the metrics were testified through statistical analyzing...
Visualizations of actual run-time data support the comprehension of programs, like examples support the explanation of abstract concepts and principles. Unfortunately, the required run-time analysis is often associated with an inconvenient overhead that renders current tools impractical for frequent use. We propose an interactive approach to collect and present run-time data. An initial shallow analysis...
Automatic and advanced merging algorithms help programmers to merge their modifications in main development repositories. However, there is little support to help release masters (integrators) to take decisions about the integration of published merged changes into the system release. Most of the time, the release master has to read all the changed code, check the diffs to build an idea of a change,...
Code smells are anomalies often caused by the way concerns are realized in the source code. Their identification might depend on properties governing the structure of individual concerns and their inter-dependencies in the system implementation. Although code visualization tools are increasingly applied to support anomaly detection, they are mostly limited to represent modular structures, such as...
Coherent Software Cities are a software visualization approach which adopts the city metaphor to support the comprehension of various aspects of evolving software systems. For this purpose, the approach implements a three-staged modeling chain yielding coherent sets of application specific visualizations. In this context, a new layout approach for software cities is presented, which explicitly takes...
The paper presents a software integration, testing and visualization tool, called Dashboard, which is based on pipe-lined backboard architecture for family of natural language processing (NLP) application. The Dashboard helps in testing of a module in isolation, facilitating the training and tuning of a module, integration and testing of a set of heterogeneous modules, and building and testing of...
Pedagogical algorithm animation systems produce graphical representations that aim to assist learners in understanding the dynamic behavior of computer algorithms. In order to foster active learning, educators have explored algorithm animation systems that empower learners to construct their own animations of algorithms under study. Notably, these systems support a similar development model in which...
Model-driven development has become the state- of-the-art approach for designing embedded real-time systems. Due to their high level of abstraction, models are easier to understand and verify, thus leading to less faulty systems. But even when combined with automatic code generation, there is still the risk of unintended behavior. This may, for example, arise from real sensor inputs which differ from...
Many techniques and tools have been developed to improve program comprehension but most tools are unsuitable for novices. Some tools are not user friendly, some designs are more suitable to expert programmers and some integrated development environments (IDEs) are very simple and fail to support program comprehension needs among the users. These factors hinder the learning process and may become obstacles...
Thanks to Rich Internet Applications (RIAs) with their enhanced interactivity, responsiveness and dynamicity, the user experience in the Web 2.0 is becoming more and more appealing and user-friendly. At the same time, the dynamic nature of RIAs, and the heterogeneous technologies, frameworks, communication models used for implementing them negatively affect their analyzability and understandability,...
The C preprocessor is often used in practice to implement variability in software product lines. Using #ifdef statements provokes problems such as obfuscated source code, yet they will still be used in practice at least in the medium-term future. With CIDE, we demonstrate a tool to improve understanding and maintaining code that contains #ifdef statements by visualizing them with colors and providing...
The design of software systems is often so intricate that no individual can grasp the whole picture. Multi-Touch screen technology combined with 3D software visualization offers a way for software engineers to interact with a software system in an intuitive way. In this paper we present first results on how such emerging technologies can be used to explore software systems.
Spatial data mining and spatial data visualization are two comparatively popular technical methods in recent years, in essence, both purpose is to find geography phenomena what spatial data express and find various knowledge and laws implicit in geography entity. so it is necessary to combine both organically and form a new research direction - Visualization Spatial Data Mining (VSDM). This paper...
This work is focused on the syntax error recovery visualization within the compilation process. We have observed that none of the existing tools, which display some views of the compilation, give a solution to this aspect. We present an educational tool called VAST which allows to visualize the different views of the compilation process. Besides, VAST allows to display different syntax error recovery...
Software engineers need to design, implement, comprehend and maintain large and complex software systems. Awareness of information about the properties and state of individual artifacts, and the process being enacted to produce them, can make these activities less error-prone and more efficient. In this paper we advocate the use of code colouring to augment development environments with rich information...
Future software systems will be dynamic service oriented systems. Service-Oriented Architecture (SOA) provides an extensible and dynamic architecture to be used, for example, in smart environments. In such an environment, software has to adapt its behaviour dynamically. Thus, there is a need for Verifying and Validating (V & V) the adaptations at run-time. This paper contributes to that by introducing...
Frequent changes to groups of software entities from different parts of the system may indicate structural issues in the system's decomposition. Analyzing such groups is needed to understand the underlying reasons for co-changes, and also determine how to resolve the issues. To date, static visualizations have been proposed to identify possible structural issues, but they help only to a certain extent...
