A Methodology for Assessment Database According to ISO 9126

A methodology for implement, design and test, and an instrument for quality inspection complying with the ISO 9126 standard was developed by the Research Group on Software Engineering, GPES, and TATA Consultancy Services at the Aeronautics Institute of Technology, ITA. GPES is a research group based on ITA. The methodology and the instrument use the Causal Analysis and Resolution, CAR, process area, based on the approach Goal, Question, indicator, and Measures (GQ(i)M). The main contributions were: a) the creation and implementation of indicators, funded on metrics, for a decision process, which are based on the construction of a quality assessment methodology for a software product, in a model of a information system; and b) a prototype of an instrument for quality, which involves the approach GQ(i)M in the definition of quantitative and qualitative metrics, by means of a Microsoft Excel spreadsheet. The methodology represents the sophistication of the Causal Analysis and Resolution technique for gain identification, using database techniques. In this article the methodology was applied to two different case studies.
