Relating computer program maintainability to software measures
نویسندگان
چکیده
It is no longer a surprise that program maintenance dominates the total cost of a large software system over its lifetime. In response to these costs, the emphasis in program design has largely shifted from the time and space issues of machine efficiency to issues of clear and flexible program structures that can be easily maintained. The goal of this project is to identify measurable program properties that influence maintainability. More precisely, we examine the effect of various program characteristics on the subsequent frequency and magnitude of program errors.

A Quantitative Evaluation of Maintainability of Software Architecture Styles
Proper decisions play a crucial role in any software architecture design process. An important decision of design stage is the selection of a suitable software architecture style. Lack of investigation on the quantitative impact of architecture styles on software quality attributes is the main problem in using such styles. Consequently, the use of architecture styles in designing is based on th...
متن کاملObject-oriented class maintainability prediction using internal quality attributes
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...
متن کاملExamining the Relationships between Software Coupling and Software Performance: A Cross-platform Experiment
Coupling measures the degree of dependencies between software modules. Considerable research has been performed to relate software coupling with software understandability, maintainability, and reusability, which are the key properties of software maintenance and evolution. However, only a few research works have been reported that study the relationships between software coupling and software ...
متن کاملOn Quality and Measures in Software Engineering
Complexity measures are mainly used to estimate vital information about reliability and maintainability of software systems from regular analysis of the source code. Such measures also provide constant feedback during a software project to assist the control of the development procedure. There exist several models to classify a software product's quality. These models often include different me...
متن کاملAn architecture-centric software maintainability assessment using information theory
Architecture-based metrics can provide valuable information on whether or not one can localize the effects of modification (such as adjusting data flows or control flows) in software and can therefore be used to prevent the changes from adversely affecting other software components. This paper proposes an architecture-centric metric using entropy for assessing structural dependencies among soft...
