As a result, the database owner is advised not only to obtain effective support services from the data provider that indicate response times and priority steps for « fixed » ones, but also a lump sum compensation clause for non-delivery, delay in delivery and strict rules on liability for data inaccuracy. The buyer must, as always, perform a duty of due diligence and request access to copies of the information made available to data subjects, copies of agreements with third parties if such agreements are to be continued or copies of complaints and the manner in which they are processed. If, in the best case, the data is delivered to the database owner in an unexpected format (intentionally or elsewhere), reprogramming (and therefore more time and costs) is required and, in the worst case, errors may occur in the service provided to the subscribers of the database. . . .
