Oracle Enterprise Performance Management allows users to access data through web browsers connected to application servers and web services. The data is stored in relational databases and Essbase databases, with metadata typically defined by dimensions like measure, version, territory, year, customer, and time period. As more depth is added to the dimensions, users can drill down or roll up from single data points to see more or less data, and analyze variances across time periods, data types, customer types, and territories.
