MicroStrategy is a business intelligence (BI), enterprise reporting, and OLAP (on-line analytical processing) software vendor. MicroStrategy's software allows reporting and analysis of data stored in a relational database, multidimensional database, or flat data file. MicroStrategy describes its core reporting software as having a "ROLAP" or "Relational OLAP" architecture, meaning that a complex relational database can be expressed using a virtual multidimensional cube structure that can be more easily understood by business users who wish to navigate through the data.
