Messages can be post dated, e.g., a bill can be created for delivery in 2 weeks. The behavior of message creation and consumption is fully synchronized with the behavior of non-message data in the same database. An analysis can be done on various levels. Examples are system response times, business process time, and business volume. Since all these cases deal with time series the available of time series technology in Oracle8 is especially helpful.
Data warehouses contain extracted data.
They are optimized to the current method of analyzing data. If the analysis changes the data warehouse data have to change. Since Message Management supports the retention of the original data, data warehouse extraction can re-execute whenever there is a need to analyze data in a different way. Again, the integration of the EAI technology into the database provides obviously the required functionality. The development of mission critical operational characteristics requires significant development resources over an extended period of time.
