Analytical Processing (OLAP) allows users to analyze database information from multiple database systems at one time. An OLAP Cube is a data structure that allows fast analysis of data according to the multiple Dimensions that define a business problem. OLAP in a data warehouse enables companies to organize information in multiple dimensions, which makes it easy for businesses to understand and use data. Since OLAP contains multidimensional data usually obtained from different and unrelated sources, it requires a special method of storing that data. OLAP tools enable users to analyze different dimensions of multidimensional data using self-service.
In our research and implementation scope, we have used OLAP method to provide corporate level multidimensional data to the business users. Corporate Information Models (CIMs) provide trusted and qualified data from multiple sources for everyone to build their own business intelligence reports and dashboards.
Corporate Information Models are Online Analytical Processing (OLAP) Cubes – a data structure that enables simple and rapid analysis of data by the multiple dimensions that define a business problem. A multidimensional cube for reporting composed of multiple Dimension e.g. Customers, Product Lines, business units and Date. By storing data using OLAP cubes, data is pre-calculated and ready-to-use, eliminating long-running data queries and enabling self-service business intelligence. A portal has been developed to provide and display the CIM detail. The CIM catalog links to over 60 CIMs categorized by the seven main categories called Value streams.
