Abstract: A system is provided for linking together a system of trading financial instruments to a system of clearing transactions in financial instruments. In a first aspect of the present invention, the linking system includes a network linking a plurality of trading systems and a clearing system. An external interface couples the trading systems to the network while a clearing interface couples the clearing system to the network. A transmitter module transmits trading information in a plurality of kinds of securities along the network from the trading system to the clearing system. That transmitting selectively occurs approximately simultaneously with the arrival of the trading information at the external interface. The transmitting also occurs independently of the selection of trading algorithm or clearing algorithm. A second aspect of the present invention involves a computerized method for coupling a plurality of trading systems and a clearing system with a network.

Abstract: A software product is produced by defining a functional model of the overall software product, designing, based on this functional model, a plurality n of configurations and slices of the software product, wherein a configuration is the entirety or a part of the software product forming an independently testable unit and a slice is a set of functions of the software product constructed together and forming the entirety or part of a configuration. The n slices are independently constructed wherein the first slice forms the first configuration. The second to n-th configurations are formed by integrating the k-th configuration with the (k?1)-th slice, wherein k is 1, . . . n?1 Subsequently a first to n-th configuration are tested independently. This software development approach allows an integration of the overall systems in parts as early as possible and to gradually increase the number of integrated components in a controlled, but manageable fashion.
