Nowadays many e-commerce companies own more than one system for handling their business. This is usually an online store, but also an ERP system for storing the data such as products, customers or invoices. It goes without saying that such data as products’ prices and current supply have to be synchronized. Otherwise, someone might e.g. buy some product which is no longer available. How should such a synchronization be made? In which format should the data be passed between the systems? Which tools and mechanisms should you use not to build everything from scratch?
