An Architecture-Oriented Data Warehouse Testing Approach
نویسندگان
چکیده
In the past few years, the data warehouse (DW) has regained experts’ interest due to the paradigm shift from data storages to data analysis. During the development of DWs data passes through a number of transformations and are staged in multiple storages which might lead to data corruption and/or manipulation. Hence, testing DWs is a vital stage in the DW development life cycle. In this paper, we will present a DW testing approach that is adjustable to fit multiple DW architectures and will present its applicability on three case studies to outline the flexibility and generality of the proposed approach.

متن کاملAspect-Oriented Logical Architecture Design A Layered Perspective Applied to Data Warehousing
In this paper we propose a layered approach for aspects’ specification and integration at the logical architecture design level. The proposed approach is based on multiple nominal views and crosscutting aspectual views, composed by architectural aspects. To demonstrate the concept applicability, we apply our ideas to a data warehouse architecture design where the metadata is represented as an a...
متن کاملImproving Architectural Design Skills with Design-Based Learning of New Structures
The purposeful and applied learning of Structures as a pillar of architectural design is very important. The current educational content of Structures in architecture departments is based on theoretical discussions, mathematical formulas, and lecture-oriented material. As a result, students are incompetent in applying practical concepts and structural formal analyses to architectural design. Ef...
