An OLAP Cube is a multidimensional array of data that can be analyzed by OLAP, a computer-based technique for processing data to find insights. For instance, you would analyze company data using variables such as product, time scale, and location to compare expenses and/or sales. Many repositories as well as source code can be found on the Web that make this kind of analysis feasible. Cask Data Application Platform (CDAP), for example, is an online framework that provides a number
of pre-packaged datasets, making it easy to store and retrieve data using best-practices-based implementations of common data access patterns. Download its source code at the CDAP Guides GitHub repository (https:// github.com/cdap-guides/cdap-cube-guide/tree/ release/cdap-3.6-compatible), install the Web components, and create a simple application able to build a “flow” for processing log entries into multidimensional facts as they are received.
