In this paper, the authors describe the approach for developing e-commerce applications from web services. The applications implemented in heterogeneous platforms and areas can collaborate through web services. Presentation layer communicates with database systems through services interface layer. The legacy system layer consists of the existing data sources and information technology systems available for each organization involved in the integrated application. The service interface layer enables the functionality of the legacy systems to be available as web services, abstracting from the implementation details.
