What is BI ?
  • Transforms raw data into meaningful and useful information for business purposes.
  • Handles large amounts of information to help identify and develop new opportunities.
  • Provides historical, current and predictive views of business operations.
  • Common functions are online analytical processing (OLAP), analytics, data mining, and predictive analytics.

Online Analytical Processing (OLAP)
  • OLAP is an approach to answering multi-dimensional analytical (MDA) queries swiftly.
  • The term OLAP was created as a slight modification of the traditional database term OLTP (Online Transaction Processing).
  • The core of any OLAP system is an OLAP cube that consists of numeric facts called measures which are categorized by dimensions.
measures and dimensions
Measures and Dimensions
  • Each measure has a set of labels, or meta-data, associated with it. A dimension is what describes these labels; it provides information about the measure.
  • A simple example would be a cube that contains a store's sales as a measure, and Date/Time as a dimension. Each Sale has a Date/Time label that describes more about that sale.
  • Any number of dimensions can be added to the structure such as Store, Cashier, or Customer by adding a foreign key column to the fact table. This allows an analyst to view the measures along any combination of the dimensions.
analytics
Analytics
  • The discovery and communication of meaningful patterns in data. Analytics relies on the simultaneous application of statistics, computer programming and operations research to quantify performance.
  • Analytics often favors data visualization to communicate insight.
data mining
Data Mining
  • The computational process of discovering patterns in large data sets involving methods at the intersection of artificial intelligence, machine learning, statistics, and database systems.
predictive analytics
Predictive Analytics
  • Makes predictions about future, or otherwise unknown, events.
  • In business, predictive models exploit patterns found in historical and transactional data to identify risks and opportunities.
  • One of the most well known applications is credit scoring, which is used throughout financial services. Scoring models process a customer's credit history, loan application, customer data, etc., in order to rank-order individuals by their likelihood of making future credit payments on time.
