A method and system for importing data comprising the downloading of product data from different sources and in different formats; processing the downloaded data by at least comparing it with data downloaded and stored in a product database; and reviewing the results of the comparison to detect differences in the data, the differences potentially being errors. The system and methods further comprise connecting the downloaded data from its supplier specific format into a standard format; comparing the downloaded data in the standard format with a previously downloaded data set saved in the standard format; categorizing the product data based on the results of the second comparison; and processing each category of data independently to automatically update the product database.
