To create business intelligence information, the integrated data are searched, analyzed, and
delivered to the decision maker. In the case of structured data, analysts use Enterprise Resource
Planning (ERP) systems, extract-transform-load (ETL) tools, data warehouses (DW), data-mining
tools, and on-line analytical processing tools (OLAP). But a different and less sophisticated set of
analytic tools is currently required to deal with semi-structured data.
