Unit 1 Datawarehouse Data Mining Pdf Data Warehouse Databases 1.2 the scope of data mining data mining derives its name from the similarities between searching for valuable business information in a large database — for example, finding linked products in gigabytes of store scanner data — and mining a mountain for a vein of valuable ore. both processes require either sifting through an immense amount of material, or intelligently probing it to find. The data warehouse exists to provide business users with direct ac cess to data, to provide a single unified version of the performance indicators, to record the past accurately, and to provide the ability to view the data from many different per spectives.
Data Mining Tutorial Pdf Data Mining Data Warehouse Course objectives: learn how to build a data warehouse and query it (using open source tools like pentaho data integration tool, pentaho business analytics). perform data mining tasks using a data mining to understand the data sets and data preprocessing. Data mining functions such as association, clustering, classification, prediction can be integrated with olap operations to enhance the interactive mining of knowledge at multiple level of abstraction. that's why data warehouse has now become an important platform for data analysis and online analytical processing. Basic concepts of data warehousing introduction, meaning and characteristics of data warehousing, online transaction processing (oltp), data warehousing models, data warehouse architecture & principles of data warehousing data mining. Data mining knowledge discovery from hidden patterns supports associations, constructing analytical models, performing classification and prediction, and presenting the mining results using visualization tools.
