A master database is consulted for records containing a set of instructions and business rules pertaining to the data integration tasks to be performed when the system is run. Detail records are retrieved with the detailed steps to be performed. The actual data integration is accomplished by calls to various software modules which perform one or more basic function necessary for the data integration. Such an approach makes it easier to set up, maintain and change the data integration, and does not require custom coding which tends to be error prone and costly to implement and to maintain.
