Portal for auto parts sales enables implementation of Auctions for a specific item. It supports information exchange with a large number of similar resources and DataBases of the automotive suppliers.Austrian company selling auto parts approached GERSIS with a request of creation of a Portal. Auto Parts Auction Portal helps to choose and buy different kinds of spare parts for various makes of cars as well as to auction the available goods (similar to eBay).The main problem we met was that lots of the products had similar characteristics and color, etc. So we had to create the filtration system that could find just the product that the customer needed.As a result, we have successfully implemented the project and created the Portal with an extensive database.Tools we used: GWT, Spring, JPA, MySql, Tomcat.
