Architecture and quality in data warehouses [chapter]

Matthias Jarke, Manfred A. Jeusfeld, Christoph Quix, Panos Vassiliadis
1998 Lecture Notes in Computer Science  
Most database researchers have studied data warehouses (DW) in their role as buffers of materialized views, mediating between updateintensive OLTP systems and query-intensive decision support.  ...  Firstly, we enrich the meta data about DW architectures by explicit enterprise models.  ...  The authors would like to thanks their project partners in DWQ, especially Maurizio Lenzerini, Mokrane Bouzeghoub and Enrico Franconi, for fruitful discussions of the architecture and quality model.  ...

A PROPOSAL OF DATA QUALITY FOR DATA WAREHOUSES ENVIRONMENT

Leo Willyanto Santoso, Kartika Gunadi
2006 Jurnal Informatika  
This metamodel enables data warehouse management, design and evolution based on a high level conceptual perspective, which can be linked to the actual structural and physical aspects of the data warehouse  ...  There is strong evidence that many organisations have significant data quality problems, and that these have substantial social and economic impacts.  ...  This is shown in Figure 4 . Finally, the metamodel complements proposed architecture and quality models in a coherent fashion, resulting in a full framework for data warehouse metamodeling.  ...

THE QUALITY OF DATA AND METADATA IN A DATAWAREHOUSE

Carmen Răduţ
2013 Strategii Manageriale  
This study will try to offer a process of obtaining quality data in data archives and how to avoid quality anomalies inside metadata.  ...  Specialty studies show that most data is not useful for the purpose it has been collected because of both the lack of quality and incorrect techniques of manipulating this data.  ...  The metadata quality control system (MQC) includes: data warehouse architecture and the overall quality which is measured along the data flow. MQC system architecture is shown in Figure 1 .  ...

Repository Support for Data Warehouse Evolution

Christoph Quix
1999 Design and Management of Data Warehouses  
Based on existing meta models for the architecture and quality of a data warehouse, we propose in this paper a data warehouse process model to capture the dynamics of a data warehouse.  ...  The evolution of a data warehouse is represented as a special process and the evolution operators are linked to the corresponding architecture components and quality factors they affect.  ...  Acknowledgments This research is sponsored by the European Esprit Project "DWQ: Foundations of Data Warehouse Quality", No. 22469.  ...

Designing a Clinical Data Warehouse Architecture to Support Quality Improvement Initiatives

John D Chelico, Adam B Wilcox, David K Vawdrey, Gilad J Kuperman
2017 AMIA Annual Symposium Proceedings  
Clinical data warehouses, initially directed towards clinical research or financial analyses, are evolving to support quality improvement efforts, and must now address the quality improvement life cycle  ...  In addition, data that are needed for quality improvement often do not reside in a single database, requiring easier methods to query data across multiple disparate sources.  ...  Some limitations exist in the architecture of a virtual data warehouse.  ...
