1 BTM’s System Goals BOOK TRADE MARKET or BTM is a software application that will allow its users to exchange books within a book community library. BTM will act as a large-scale library without facing its practical limits. BTM grows according to the size of its community. BTM enables people to exchange items with each other (P2P) in a free and non-monetary way. BTM keeps an updated Data Base information on each user, on his or her items, on his or her present and past book transactions in order to guarantee an exchange security and reliability. As a result, BTM suppresses the need for any physical infrastructure, and thus creates an outstanding flexibility and growing potential in the system.
