Business Intelligence (BI) Analytics goes beyond reporting to an advanced level of interaction with information, using more sophisticated techniques and tools. Learn more about these approaches here. Be sure to revisit as we expand this information.

 

 


OLAP Cubes

About Cubes
A "cube" or data cube is an advanced tool for data analysis that provides fast and easy data manipulation from multiple perspectives. The cube provides a visual representation of a three-dimensional data structure. However, the true nature of a data cube is multi-dimensional; it is not limited to three dimensions.

A "dimension", in terms of data analysis, is the "by" portion of a statement. For example, if you were analyzing the number of students by campus, by college, by major concentration, by credit hours, by gender, each of these qualifiers would represent a dimension. The cube allows for analyzing the data in this multi-dimensional way.
A "measure" or "fact" is simply the item being counted by the cube. Using the previous example, the "number of students" is the measure or fact being analyzed by the cube.

"OLAP" is an acronym for On-Line Analytical Processing. This differs from relational databases that record a series of transactions called "OLTP" or On-Line Transactional Processing. While OLTP tools are very powerful and effective for reports, they are very slow when an entire database or data collection must be summarized. OLAP performs much better in that arena.
