“…Furthermore, the existing approaches of software modularization for changing the structure of package entail costly maintenance overhead, complicating its understandability and comprehension [8], [9]. Abdeen et al recently proposed a package level metrics suite which support the modularization of source code architecture using existing package structure, thus without affecting prevalent software design adversely [10].…”

Abstract-Role of packages in organization and maintenance of software systems has acquired vital importance in recent research of software quality. With an advancement in modularization approaches of object oriented software, packages are widely considered as re-usable and maintainable entities of objectoriented software architectures, specially to avoid complicated dependencies and insure software design of well identified services. In this context, recently research study of H. Abdeen on automatic optimization of package dependencies provide composite frame of metrics for package quality and overall source code modularization. There is an opportunity to conduct comprehensive empirical analysis over proposed metrics for assessing their usefulness and application for fault-prediction, design flaw detection, identification of source code anomalies and architectural erosion. In this paper, we examine impact of these dependency optimization based metrics in wide spectrum of software quality for single package and entire software modularization. Our experimental work is conducted over open source software systems through statistical methodology based on cross validation fault-prediction and correlation. We conclude with empirical evidence that dependency based package modularization metrics provide more accurate view for predicting fault-prone packages and improvement of overall software structure. Thus, application of these metrics can help the developers and software practitioners to insure proactive management of the source code dependencies and avoid design flaws during software development.

“…Mitchell and Mancoridis [Mitchell and Mancoridis 2006] use the same technique in Bunch, a tool supporting automatic system decomposition. Search-based approaches are also used in several other works [Harman et al 2002;Praditwong et al 2011;Seng et al 2005;Abdeen et al 2009]. In particular, Harman et al [Harman et al 2002] and Seng et al [Seng et al 2005] use a single-objective genetic algorithm to improve the subsystem decomposition of a software system, where the fitness function is defined using a combination of quality metrics.…”

Oftentimes, during software maintenance the original program modularization decays, thus reducing its quality. One of the main reasons for such architectural erosion is suboptimal placement of source code classes in software packages. To alleviate this issue, we propose an automated approach to help developers improve the quality of software modularization. Our approach analyzes underlying latent topics in source code as well as structural dependencies to recommend (and explain) refactoring operations aiming at moving a class to a more suitable package. The topics are acquired via Relational Topic Models (RTM), a probabilistic topic modeling technique. The resulting tool, coined as R3 (Rational Refactoring via RTM), has been evaluated in two empirical studies. The results of the first study conducted on nine software systems indicate that R3 provides a coupling reduction from 10% to 30% among the software modules. The second study with 62 developers confirms that R3 is able to provide meaningful recommendations (and explanations) for move class refactoring. Specifically, more than 70% of the recommendations were considered meaningful from a functional point of view.

“…It should be noted that we do not oppose fingerprints to other techniques; on the contrary, we see them as complementary. For example, independently of this work and this article, we developed complementary tools to help dealing with packages such as Package Blueprints (which is based on a zoom-out visualization and ordering of internal references between packages) [DPS + 07]; Orion (which supports the prediction of change impact) [LDDK09] and a Simulated Annealing search-based technique to help maintainers find good alternative modularizations [ADSA09]. Maintainers can then use the fingerprints to compare the results, understand the alternatives, and choose the most suitable modularization.…”

Context: Object-oriented languages such as Java, Smalltalk, and C++ structure their programs using packages. Maintainers of large systems need to understand how packages relate to each other, but this task is complex because packages often have multiple clients and play different roles (class container, code ownership. . . ). Several approaches have been proposed, among which the use of cohesion and coupling metrics. Such metrics help identify candidate packages for restructuring; however, they do not help maintainers actually understand the structure and interrelationships between packages.Objectives: In this paper, we use pre-attentive processing as the basis for package visualization and see to what extent it could be used in package understanding.Method: We present the package fingerprint, a 2D visualization of the references made to and from a package. The proposed visualization offers a semantically rich, but compact and zoomable views centered on packages. We focus on two views (incoming and outgoing references) that help users understand how the package under analysis is used by the system and how it uses the system.Results: We applied these views on four large systems: Squeak, JBoss, Azureus, and ArgoUML. We obtained several interesting results, among which, the identification of a set of recurring visual patterns that help maintainers: (a) more easily identify the role of and the way a package is used within the system (e.g., the package under analysis provides a set of layered services), and, (b) detect either problematic situations (e.g., a single package that groups together a large number of basic services) or opportunities for better package restructuring (e.g., removing cyclic dependencies among packages). The visualization generally scaled well and the detection of different patterns was always possible.Conclusion: The proposed visualizations and patterns proved to be useful in understanding and maintaining the different systems we addressed. To generalize to other contexts and systems, a real user study is required.
