In the past two decades both the industry and the research community have proposed hundreds of metrics to track software projects, evaluate quality or estimate effort. Unfortunately, it is not always clear which metric works best in a particular context. Even worse, for some metrics there is little evidence whether the metric measures the...

In the evaluation of implemented software architectures, metrics can be used to provide an indication of the degree of encapsulation within a system and to serve as a basis for an informed discussion about how well-suited the system is for expected changes. Current literature shows that over 40 different architecture-level metrics are available...

In this paper we introduce the concept of a -dependency profile-, a system level metric aimed at quantifying the level of encapsulation and independence within a system. We verify that these profiles are suitable to be used in an evaluation context by inspecting the dependency profiles for a repository of almost 100 systems. Furthermore we...

The decomposition of a software system into components is a major decision in any software architecture, having a strong influence on many of its quality aspects. A system’s analyzability, in particular, is influenced by its decomposition into components. But into how many components should a system be decomposed to achieve optimal analyzability...

Evaluating the complexity of the architecture of a softwaresystem is a difficult task. Many aspects have to be considered to come to a balanced assessment. Several architecture evaluation methods have been proposed, but very few define a quality model to be used during the evaluation process. In addition, those methods that do introduce a...

Accepted for publication in the Proceedings of the International Conference on Software Maintenance (ICSM), 2009, IEEE Computer Society. Software architecture evaluation methods aim at identifying potential maintainability problems for a given architecture. Several of these methods exist, which typically prescribe the structure of the evaluation...

A wide range of parser generators are used to generate parsers for programming languages. The grammar formalisms that come with parser generators provide different approaches for defining operator precedence. Some generators (e.g. YACC) support precedence declarations, others require the grammar to be unambiguous, thus encoding the precedence...
