System and method for optimizing the loading of data submissions

A system and method for detecting changes in data records based on summary values calculated on input data and existing data in a database is provided. An input data record including indicative data and financial data may be received. The indicative data may be normalized. A summary value may be calculated based on the normalized data to determine if any differences between the input record and existing data exist. If an existing summary value corresponding to the input record does not exist, the calculated summary value and financial data may be stored. If an existing summary value corresponding to the input record exists, the calculated summary value and the existing summary value may be compared to determine if they are equivalent. The calculated summary value and financial data may be stored if the summary values are not equivalent. The financial data may be stored if the summary values are equivalent.
