Enterprise Resource Planning is a subject of fundamental importance for companies of all sizes, allowing them to efficiently manage company assets. Nonetheless, a proper ERP process requires a non-negligible amount of up-to-date and reliable information in order to be able to effectively schedule enterprise resources. On the other hand, more and more companies start adopting Customer Relationship Management tools - mainly in the form of software solutions - to better handle their interactions with customers, making available a huge amount of data relative to the company's sales history. However, such data is usually just an historic collection and is not directly exploitable for ERP purposes.
