5 History of Data Warehousing
Data warehouses extend the transformation of data into information In the 1990’s executives became less concerned with the day-to-day business operations and more concerned with overall business functions The data warehouse provided the ability to support decision making without disrupting the day-to-day operations

Data warehouse – a logical collection of information – gathered from many different operational databases – that supports business analysis activities and decision-making tasks The primary purpose of a data warehouse is to aggregate information throughout an organization into a single repository for decision-making purposes

7 Data Warehouse Fundamentals
Extraction, transformation, and loading (ETL) – a process that extracts information from internal and external databases, transforms the information using a common set of enterprise definitions, and loads the information into a data warehouse Data mart – contains a subset of data warehouse information

8 Data Warehouse Fundamentals

9 Multidimensional Analysis and Data Mining
Databases contain information in a series of two-dimensional tables In a data warehouse and data mart, information is multidimensional, it contains layers of columns and rows Dimension – a particular attribute of information

10 Multidimensional Analysis and Data Mining
Cube – common term for the representation of multidimensional information

11 Multidimensional Analysis and Data Mining
Data mining – the process of analyzing data to extract information not offered by the raw data alone To perform data mining users need data-mining tools Data-mining tool – uses a variety of techniques to find patterns and relationships in large volumes of information and infers rules that predict future behavior and guide decision making

12 Information Cleansing or Scrubbing
An organization must maintain high-quality data in the data warehouse Information cleansing or scrubbing – A process that weeds out and fixes or discards inconsistent, incorrect, or incomplete information
