A Survey on Temporal Data Warehousing

open access: yesInternational Journal of Data Warehousing and Mining, 2009
Data warehouses are information repositories specialized in supporting decision making. Since the decisional process typically requires an analysis of historical trends, time and its management acquire a huge importance. In this paper we consider the variety of issues, often grouped under term temporal data warehousing, implied by the need for ...

Data stream warehousing

2014 IEEE 30th International Conference on Data Engineering, 2013
Data stream warehousing is a data management technology designed to simultaneously handle big-data and fast-data. Conceptually, a data stream warehouse can be thought of as a data warehouse system that is updated in nearly-real time rather than during downtimes, or as a data stream management system that stores a very long history. In this tutorial, we

Preparing complex data for warehousing

The 3rd ACS/IEEE International Conference onComputer Systems and Applications, 2005., 2005
Summary form only given. In order to prepare complex data for relevant analysis, a data warehousing-based approach is needed. However, a good multidimensional modeling requires efficient preparation of data starting with a data integration phase. We present in this paper two principal steps of the complex data warehousing process.

Data warehousing techniques

Proceedings of the International Conference & Workshop on Emerging Trends in Technology - ICWET '11, 2011
DW is an information delivery system. It is a repository of integrated information, available for queries and analysis. Data & information are extracted from heterogeneous sources as they are generated. This makes it much easier & more efficient to run queries over data that originally came from different sources.
