Context: Class maintainability is the likelihood that a class can be easily modified. Before releasing an object-oriented software system, it is impossible to know with certainty when, where, how, and how often a class will be modified. At that stage, this likelihood can be estimated using the internal quality attributes of a class, which include cohesion, coupling, and size. To reduce the futu...

As a key early artefact in the development of OO software, the quality of class diagrams is crucial for all later design work and could be a major determinant for the quality of the software product that is finally delivered. Quantitative measurement instruments are useful to assess class diagram quality in an objective way, thus avoiding bias in the quality evaluation process. This paper prese...

A challenge in software design is to find solutions that balance and optimize the quality attributes of the application. In this paper we present a case study of an application and the results of a design decision made on weak assumptions. The application has been assessed with respect to performance and maintainability. We present and evaluate an alternative design of a critical system compone...

The software engineering community aims to achieve and maintain high-efficient practical activities. One of the techniques used for this purpose is Test-Driven Development (TDD), which a cyclic test-centered development method positively related maintainability, may vary depending on context application. Previous research has indicated that TDD's benefits maintainability be due improved focus c...

Security is a requirement of utmost importance to produce high-quality software. However, there still considerable amount vulnerabilities being discovered and fixed almost weekly. We hypothesize that developers affect the maintainability their codebases when patching vulnerabilities. This paper evaluates impact patches improve security on open-source Maintainability measured based Better Code H...

Over the last decade, several authors have studied the maintainability of software architectures. In particular; the assessment of maintainability has received attention. However; even when one has a quantitative assessment of the maintainability of a software architecture, one still does not have any indication of the optimality of the software architecture with respect to this quality attribu...

There are many benefits of checking design constraints at runtime—for example, automatic detection of design drift or corrosion. However, there is no comparative analysis of different approaches although such an analysis could provide a sound basis for determining the appropriateness of one approach over the others. In this paper we conduct a comparative analysis and evaluation of different con...

Program refactoring—transforming a program to improve readability, structure, performance, abstraction, maintainability, or other characteristics— is not applied in practice as much as might be desired. Although there are various possible reasons why program refactoring is not so popular, one deterrent is the cost of detecting candidates for refactoring and of choosing the appropriate refactori...
