The market for business intelligence has evolved steadily in recent years and is also heavily dominated by the most important and well-known providers such as SAP, Oracle, IBM, SAS, Microsoft, and OpenSource. These companies offer software for start-ups that can successfully handle the five tasks of business intelligence, i.e., the collection, integration, storage, processing, and presentation of data. Also, the overall BI market is divided into the segments BI user tools (BI front ends) and BI data management (BI backend). BI front-ends include OLAP and multidimensional databases, data mining, dashboards, balanced scorecards, planning, reporting, and consolidation. The BI backend comprises software for data integration, data quality management, master data management, as well as relational or analytical databases in BI systems. In principle, many projects in the front-end area were initiated in start-ups, while investments in the back-end infrastructure are still reserved.
