There are more and more incompatible systems with the growing number of services provided by computers. The user has to chose between expensive huge systems, offered by large companies like Microsoft or Oracle and losing competition. While these huge systems have a lot of possibilities, small and middle sized companies can only use a small portion of options offered there. With the increasing pressure from competitors, this forces users to choose other technologies like Web Services, in order to survive rivalry. WSDL (Web Services Description Language) was invented to describe Web Services in the most simple way there is. Web Service is a collection of protocols and standards used for exchanging data between applications or systems. Software applications written in various programming languages and running on various platforms can use web services to exchange data over computer networks like the Internet in a manner similar to inter-process communication on a single computer. In this work the methods are suggested for creation of stand-alone E-Commerce Hub and combining other systems into it. By the help of Web Services, users of Internet Stores, and other systems based on product and service data, are able to share their information with others through the E-Commerce Hub. It is easily automated and requires no maintenance.
