.. i18n: Important to all of the above applications is the ability to provide managers with the information they need to make effective decisions about an organization's strategic directions. The key indicator of a successful OLAP application is its ability to provide information as needed, i.e., its ability to provide "just-in-time" information for effective decision-making. This requires more than a base level of detailed data.

.. i18n: Just-in-time information is computed data that usually reflects complex relationships and is often calculated on the fly. Analyzing and modeling complex relationships are practical only if response times are consistently short. In addition, because the nature of data relationships may not be known in advance, the data model must be flexible. A truly flexible data model ensures that OLAP systems can respond to changing business requirements as needed for effective decision making. Although OLAP applications are found in widely divergent functional areas, they all require the following key features:
