Towards a service-oriented architecture : a framework for the design of financial trading applications in the South African investment banking environment

Abstract

Service-Oriented Architecture (SOA) enables organisations to let their business drive their IT strategy, and creates a technology strategy that is aligned with that of the business. SOA is an architectural style that enables the integration of disparate systems, independent of the implementation technology or physical location, through encapsulating and integrating business processes as a collection of coarse grained, loosely-coupled services. This article aims to examine the ability of SOA to satisfy the requirements and concerns posed by financial trading systems, and to present a SOA framework for building an automated trading application.Diens-georiënteerde argitektuur (Service-Oriented Architecture (SOA)) stel organisasies in staat om die IT-strategie vanuit die besigheid te bestuur, en skep 'n tegnologiestrategie wat belyn is met dié van die besigheid. SOA is 'n argitektoniese styl wat die integrasie van uiteenlopende stelsels moontlik maak, onafhanklik van die implementeringstegnologie of fisiese ligging, deur besigheidsprosesse te enkapsuleer en te integreer as 'n versameling van losweg-gekoppelde dienste. Die doel van hierdie artikel is om SOA te ondersoek as 'n moontlikheid om te voldoen aan die vereistes en knelpunte wat finansiële handelstelsels stel, en om 'n SOA-raamwerk vir die bou van 'n outomatiese handelsapplikasie te bied.
