Application architectures of enterprise information systems versus service oriented architecture

Abstract

There are two different enterprise IS architectures, older application architecture and younger service oriented architecture. The application architecture its structural element is a classical web-based application can accept a partial or complex solution of enterprise IS. The first has got problems with data-process-communication integrity disturbing among IS applications. The second is convenient for large enterprises not for small and intermediate. Classical web-based applications are too inflexible to accepted necessary changes concerning a progress in the enterprise market-production environment.The service oriented architecture of IS can be based on enterprise web-services. Computerization of such small and flexible units can be given by classical web-services. There is constructed a new web-based application that plays a structural unit role for service oriented architecture. This application consists of a sequence formed by enterprise web-services calling. Enterprise web-services can easily accept necessary changes concerning a progress in the enterprise market-production environment. That‘s why contemporary younger service oriented architecture seems to be more acceptable for any enterprise than older application architecture.
