Data Warehouses and Data Mining

Types of Data Warehouses

There are three types of data warehouse applications:

  1. Information processing: The data can be accessing by means of querying, basic statistical analysis, reporting using crosstabs, tables, charts or graphs.
  2. Analytical processing: The data can be analyzed by means of basic OLAP operations, including slice and dice, drill down, drill up, and pivoting.
  3. Data mining: Data mining supports knowledge discovery by finding hidden patterns and associations, constructing analytical models, performing classification, and prediction.
