Architecture and quality in data warehouses
[chapter]
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
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
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
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. ...
