Data warehouse process management

Panos Vassiliadis, Christoph Quix, Yannis Vassiliou, Matthias Jarke
2001 Information Systems  
This paper complements this work with the modeling of the dynamic parts of the data warehouse.  ...  The proposed metamodel of data warehouse operational processes is capable of modeling complex activities, their interrelationships, and the relationship of activities with data sources and execution details  ...  All data stores of the data warehouse and client level which are populated from this particular view must be examined with respect to their schema, content and population processes.  ...

Using Ontologies for the Design of Data Warehouses

Jesus Pardillo, Jose Norberto Mazon
2011 International Journal of Database Management Systems  
This work is a starting point for discussing the convenience of using ontologies in data warehouse design.  ...  Based on our experience, we have detected a set of situations we have faced up with in real-world projects in which we believe that the use of ontologies will improve several aspects of the design of data  ...  Furthermore, available data sources should be taken into account since they will populate the data warehouse.  ...

Hybrid Approaches for Data Cleaning in Data Warehouse

Prerana S.Kulkarni, J. W. Bakal
2014 International Journal of Computer Applications  
Data warehouse is the only viable solution that can bring that dream into a reality. The quality of the data can only be produced by cleaning data prior to loading into data warehouse.  ...  The quality of data can only be improved by cleaning data prior to loading into the data warehouse as correctness of data is essential for well-informed and reliable decision making.  ...  INTRODUCTION Data cleaning is an essential step in populating and maintaining data warehouses. Data Warehouses needs extensive support for cleaning the data. It is used for decision making.  ...

2012 International Conference on Management of Data  
Actually, SDB are serious candidates for business intelligence applications built around the Data Warehouse (DW) technology.  ...  Actually, DW technology is quite mature for traditional data sources. As a consequence, leveraging its steps to deal with SDB becomes a necessity.  ...  We defined a generic ETL algorithm, based on ten generic operators defined in the literature, that aims at populating the target DW schema, by data from SDB.  ...
