If a company owns a data warehouse then different operational systems data is copied to that data warehouse. This usual
big amount of data on company information is then used in business decision supporting research.
A data warehouse therefore contains all the company customer data from different operational systems which is
maintained in these different systems. If customer information from these operational systems is not correlated then this
information will also not be correlated in the warehouse.
MatchMaker offers the possibility to add an unique key to each customer of your company. This key basically from that
point on correlates all the data in the different operational systems. New business supporting research can than produce more
accurate and complete information using the information on each unique customer.
