A financial information services client's indices are currently maintained in three separate systems - SPICE, FAME and EMDB. These three systems have different hardware, software and databases. The Index Integration System (IIS) consolidates the three isolated systems to establish a single, integrated platform where all major index families would be managed as one single system. This would deliver a consistent end product through uniform treatments within methodology with Lower Index production and System maintenance costs. It creates a system architecture that is extensible to accommodate the increasing number of indices and other asset classes to have a single, intuitive user interface among Index Data Analysts.
