This article discusses the data sources organizations use to populate their business intelligence systems. In addition to internal data sources, often created due to the operation of business transaction processing systems, organizations are now also using numerous external data sources. Such external data sources may include government data, social media data, research data, and so on. Think about the kind of data that you use in your personal or business life. What data do you require to make decisions? Where do you find this data? How do you process or analyze this data to help you make decisions?
Personal Data
In most cases, decision makers doing a business intelligence study rely on data and personal evaluations kept in workbooks or local databases on their computers. One of the goals of knowledge management systems is to retrieve such data and integrate it with structured data from both internal and external sources.
