Faster insights—each individual data source is limited in its ability to support certain decisions. The data warehouse can easily combine and evaluate all relevant data sources, providing insights in near real time. Smarter decision-making—data warehouses support BI functions such as data mining (...
Build high-performance and flexible data warehouse platform as a foundation for sophisticated analytics to support your business intelligence initiatives.
Data Mining Process In Datawarehouse A data warehouse is modeled for a multidimensional data structure called data cube. Each cell in a data cube stores the value of some aggregate measures. Data mining in multidimensional space carried out in OLAP style (Online Analytical Processing) where it all...
Data mining 数据挖掘 Data mining is the process of massaging the data held in the data warehouse into more useful information. Data-mining tools are used to find an association and correlation in data to produce metadata. Metadata can show previously unseen relationships...
