UNIFIED WAGERING DATA MODEL

A disadvantage of existing betting operations is the implementation of fixed odds and pari-mutuel betting on specific and dedicated systems. This results in higher acquisition and maintenance costs as compared with a single system. According to the present invention, a single system allows both fixed odds and pari-mutuel betting to be offered on a single system wherein the system effects a computer-implemented method of wagering, including: receiving, via a communications network, a wager from a customer in respect of a wagered event and a wagered product; storing the wager, in an electronic data store, and associating the wager with the wagered event, the wagered product and a customer account, wherein the computer system manages the electronic data store, having stored therein, a plurality of events, a plurality of products and a plurality of customers, all of which are independently defined.
