The IBM IMS™ database stores data using a hierarchical model that differs from the relational databases like IBM DB2. A typical IMS database stores the data using blocks called segments and each segment can contain several pieces of data called fields. Most organizations have their operational databases stored in the IMS databases; now they can use IBM Cognos® to make informed decisions over the IMS database.
This IBM Redpaper™ provides guidance for consuming IMS databases through the IBM Cognos Business Intelligence tool. It supplements the information provided by the IBM Redbooks® publication IMS Integration and Connectivity Across the Enterprise, SG24-8174
