Abstract: An information and reporting system is used in conjunction with a plurality of incompatible legacy system databases. The legacy system applications and databases continue to operate in a normal manner. The information and reporting system operates as an overlay to each of the existing legacy systems. Each local system includes a unique entity transfer that reads specified files from a legacy system database. The data within the legacy system database is mapped into a group of predefined XML documents which are transmitted to an XML service. The XML service provides a quality control examination and forwards the XML documents to a set of domain entity controllers. The controllers receive the XML documents and selectively extract data from these documents and store the data on a common format database, which is standardized for use in all of the local systems.
