1. A computer-implemented system for processing data, comprising: a user interface for enabling a user to enter mapping data to enable incoming health insurance data to be converted to a common data format; a database for storing the mapping data and data quality rules, wherein the data quality rules include data quality structure rules and data trending requirements; a receiver for receiving data from a data source; and a computer processor for automatically formatting the received data into the common data format using the mapping data input by the user to create common format data, wherein the computer processor applies the data quality rules to the common format data to identify potential errors in the common format data and notifies the user of any common format data containing one or more potential errors to enable the user to resolve the one or more potential errors in the common format data to complete quality checking of the common format data, wherein the user may redefine the mapping data or data quality rules to enable acceptance of values in the common format data identified as containing the one or more potential errors.
