	abstract = {The IBM i mainframe was designed to manage business applications for which the reliability and quality is a matter of national security. The RPG programming language is the most frequently used one on this platform. The maintainability of the source code has big influence on the development costs, probably this is the reason why it is one of the most attractive, observed and evaluated quality characteristic of all. For improving or at least preserving the maintainability level of software it is necessary to evaluate it regularly. In this study we present a quality model based on the ISO/IEC 25010 international standard for evaluating the maintainability of software systems written in RPG. As an evaluation step of the quality model we show a case study in which we explain how we integrated the quality model as a continuous quality monitoring tool into the business processes of a mid-size software company which has more than twenty years of experience in developing RPG applications.},

	abstract = {Software development in C/C++ languages is tightly coupled with preprocessor directives. While the use of preprocessor constructs cannot be avoided, current IDE support for developers can still be improved. Early feedback from IDEs about misused macros or conditional compilation has positive effects on developer productivity and code quality as well. In this paper we introduce a service layer for the Visual Studio to make detailed preprocessor information accessible for any type of IDE extensions. The service layer is built upon our previous work on the analysis of directives. We wrap the analyzer tool and provide its functionality through an API. We present the public interface of the service and demonstrate the provided services through small plug-ins implemented using various extension mechanisms. These plug-ins work together to aid the daily work of developers in several ways. We provide (1) an editor extension through the Managed Extensibility Framework which provides macro highlighting within the source code editor; (2) detailed information about actual macro substitutions and an alternative code view to show the results of macro calls; (3) a managed package for discovering the intermediate steps of macro replacements through a macro explorer. The purpose of this work is twofold: we present an additional layer designed to aid the work of tool developers; second, we provide directly usable IDE components to express its potentials.},

	abstract = {Both for software developers and managers it is crucial to have information about different aspects of the quality of their systems. This chapter gives a brief overview about the history of software product quality measurement, focusing on software maintainability, and the existing approaches and high-level models for characterizing software product quality. The most widely accepted and used practical maintainability models and the state-of-the-art works in the subject are introduced. These models play a very important role in software evolution by allowing to estimate future development costs, assess risks, or support management decisions. Based on objective aspects, the implementations of the most popular software maintainability models are compared and evaluated. The evaluation includes the Quality Index, SQALE, SQUALE, SIG, QUAMOCO, and Columbus Quality Model. The chapter presents the result of comparing the features and stability of the tools and the different models on a large number of open-source Java projects.},

Most of Sonar Qubes original analysis results are replaced (including the detected source code duplications), while the range of available analyses is extended with a number of additional metrics and issue detectors. Additionally, the plug-in offers new GUI features on the Sonar Qube dashboard and drilldown views, making the Sonar Qube user experience more comfortable and the work with the tool more productive.},

It is built upon a usability model, it calculates usability metrics, it integrates questionnaires and it also ensures several meaningful reports.
