    A novel approach to formalize Object-Oriented Design Metrics
    (2005) El-Wakil, M; El-Bastawisi, Ali; Riad, M; Fahmy, A
    Despite the extensive and solid research literature on Object-Oriented Design Metrics (OOD Metrics), a recent survey that was conducted to assess the exploitation of metrics collection and analysis in the design phase within the software industry in Sweden [1], indicated that only 21% of the survey respondents collect metrics in the design phase. 55% of the respondents to the same survey said that they consider metrics collection as a difficult process. A major reason of the difficulty of collecting design metrics is the lack of a common syntax or a common language to express OOD metrics. This lack resulted in shortage of tools that automate collecting design metrics. Researchers who propose OOD metrics express them in plain English or as mathematical formulas. Plain English allows different interpretations for the same metric. Mathematical formulas should be based on a mathematical model, which does not exist for Object-Oriented designs. In this paper, we propose expressing metrics as XQuery expressions that targets XMI documents. XMI documents offer a standard way for representing object-oriented designs, specifically UML diagrams. Also, we present Design-Metrics Crawler, which is a software tool that applies our proposa

    Object-Oriented Design Quality Models A Survey and Comparison
    (2004) El-Wakil, Mohamed; El-Bastawisi, Ali; Boshra, Mokhtar; Fahmy, Ali
    Since 1994, many Object-Oriented Design (OOD) quality models had appeared. OOD quality models aim is assessing OOD quality characteristics, such as maintainability, in a quantitative way through establishing relationships between OOD quality characteristics, and metrics computable from OOD diagrams, such as Depth of Inheritance Tree (DIT). This paper presents the results of our survey of the major OOD quality models appeared in literature since the MOOSE model in 1994, till the QMOOD model in 2002, then it proposes a set of desirable properties that should be possessed by OOD quality models and acomparison among the presented models with respect to the proposed desirable properties set
