MIS: Business Intelligence
This document discusses big data and business intelligence. It defines big data as large volumes of varied data that is collected and processed rapidly. It outlines different types of primary BI systems including reporting systems, data mining systems, knowledge management systems, and expert systems. It also discusses challenges with raw data and the need for data warehousing to extract, clean, and prepare data from different sources for BI processing and analysis. Finally, it provides an example of how a mountain resort (MRV) could use BI and data warehousing to develop a data storage plan, generate reports on repeat business, identify high-value customers, and analyze equipment usage.

Editor's Notes
- #5 Volume is actually a benefit. The benefit gained from the ability to process large amounts of information is the main attraction of big data analytics. Having more data beats out having better models: simple bits of math can be unreasonably effective given large amounts of data. If you could run that forecast taking into account 300 factors rather than 6, could you predict demand better? This volume presents the most immediate challenge to conventional IT structures. It calls for scalable storage, and a distributed approach to querying. Many companies already have large amounts of archived data, perhaps in the form of logs, but not the capacity to process it.
