Toward a New Approach for Modeling Dependability of Data Warehouse System

TL;DR

This paper proposes a new methodology inspired by Model Driven Architecture to integrate dependability aspects such as availability, reliability, maintainability, and security into Data Warehouse System design from the early stages.

Contribution

It introduces a novel approach for modeling dependability in Data Warehouse Systems, emphasizing early integration during development.

Findings

Dependability aspects can be effectively modeled using the proposed approach.

Early integration of dependability improves overall system robustness.

The approach considers interactions among different dependability properties.

Abstract

The sustainability of any Data Warehouse System (DWS) is closely correlated with user satisfaction. Therefore, analysts, designers and developers focused more on achieving all its functionality, without considering others kinds of requirement such as dependability s aspects. Moreover, these latter are often considered as properties of the system that will must be checked and corrected once the project is completed. The practice of "fix it later" can cause the obsolescence of the entire Data Warehouse System. Therefore, it requires the adoption of a methodology that will ensure the integration of aspects of dependability since the early stages of project DWS. In this paper, we first define the concepts related to dependability of DWS. Then we present our approach inspired from the MDA (Model Driven Architecture) approach to model dependability s aspects namely: availability, reliability, maintainability and security, taking into account their interaction.
