Dwarf batt: uma ferramenta de teste baseado em defeitos para data warehouse

Abstract

The data analysis process is crucial to the decision-making process in institutions. In this context, a storage structure based on Data Warehouses enables a more dynamic view of the business process. However, to create and validate these databases, tests are needed. This paper presents a study of the mutation analysis technique in Data Warehouses. The tool was developed in the Java language and the contribution of this work is the software test study and, consequently, the testing tool. To validate the tool, a study case with real data was applied, resulting promising preliminary results.
