Presentation

Toward Enterprise SOA Patterns
In 2007 PDEV was responsible for two major enterprise SOA developments on the .NET platform. Both developments were at two of South Africa’s major financial institutions and were crucial to the institute’s line of business and compliance to the National Credit Act. Both developments were loan applications and both were planned on the same technological platform: Windows Communication Foundation (WCF) for web services and Smart Client Software Factory (SCSF) for User Interface. Both applications were distributed and had to integrate to disparate legacy systems. The fundamental architecture of each application, however, differed. This presentation will analyze the architectural choices made in each application and will attempt to delineate the advantages and disadvantages of each approach. The comparison serves as a pointer toward a pattern-based approached to SOA. Fowler’s Patterns of Enterprise Application Architecture is becoming outdated in the world of SOA. This presentation attempts to point the way to Patterns of Enterprise SOA Architecture.
