Abstract

GEOS (Global Entity Order System) is a mainframe-based financial software system developed for straight-through real-time processing of securities and derivatives transactions. It consists of 6000 KLOC written in C and is accessed by a C++ front-end. In 1999 it was decided to extend the functionality to online stock brokerage with multiple front-ends such as a Java Swing client, HTML browser or WAP-enabled device. Due to its size and complexity, enhancing the mainframe system beyond its original design scope is difficult and might decrease its reliability. Consequently, the new functionality was moved into a satellite system (SDS Internet Banking), considering the mainframe system a black box. The online stock brokerage extension was implemented as a distributed system using JAVA, CORBA, Servlet API, JSP and XML
