Interface to Amazon Marketplace

First, product data such as a product description and inventory figures are sent from the internal enterprise resource planning system to Amazon Marketplace. Incoming purchase orders are queried via the web service, transferred to the internal enterprise resource planning system and processed there using the existing logic. The current processing status (e.g. "sent") of a purchase order is transferred to Amazon Marketplace for the purpose of informing the purchaser. These flows of information are each implemented in Talend Data Services by means of dedicated routines with access to the local Java API. The most important modules that Java API provides are functions for signing and encoding in accordance with MD5. The data to be transferred to Marketplace are exported from the internal Oracle database and converted into CSV or XML format, according to the Amazon specifications.
