Document Summary

Data visualization tools move beyond excel graphs and charts into sophisticated analysis techniques such as pie charts, controls, instruments, maps, time-series graphs, and more. A data warehouse is a logical collection of information, gathered from many different operational databases, that supports business analysis activities and decision-making tasks. Information scrubbing and information cleansing describe the process for weeding out, fixing, or discarding inconsistent, incorrect, or incomplete information. A data mart contains a subset of data warehouse information. Extraction, transformation, and loading is a process that extracts information from internal and external databases, transforms it using a common set of enterprise definitions, and loads it into a data warehouse. A cube is the common term for the representation of multidimensional information. Infographics display information graphically so it can be easily understood. Data-mining tools use a variety of techniques to find patterns and relationships in large volumes of information that predict future behavior and guide decision-making.
