Model-Driven Development in implementing integration flows

Górski T.

Journal of Theoretical and Applied Computer Science

2015

Vol. 9, nr 2

66--82

Integration of many different IT systems makes the integration project highly complex. The process of constructing architectural models and source code can be automated through the application of transformations. As a result, the duration time of designing or implementation, as well as the work input involved can be reduced. The purpose of the paper is to present an approach to automation of designing one of the key elements of an integration platform, namely, integration flows. The author proposes model-to-code transformation IntegrationFlow-to-Java which automates the implementation of integration flows applications for selected mediation patterns. The integration flows generator has been incorporated as a plug-in into the IBM Rational Software Architect (RSA). The RSA plugin which generates complete Java EE application of integration flow from mediation flows diagram. Thus eliminates design and programming stage in WebSphere Integration Developer which reduces development time and costs of licenses. Model-Driven Development is approach which can lead to automation of design and programming stage in software development. The IntegrationFlow-to-Java transformation offers an opportunity to reduce the duration time of the integration flows implementation forty times (with one hundred flows to be implemented). The outcomes support the significance of using transformations when designing complex IT systems, especially when integration solutions are developed.

W wielu realizowanych obecnie projektach informatycznych pojawiają się zadania dotyczące łączenia różnych systemów informatycznych. Wraz ze wzrostem liczby nieudanych projektów integracyjnych oraz rosnących kosztów utrzymania zintegrowanych systemów zaczęto szukać rozwiązań, które ułatwiły by ten proces. Jednym z takich rozwiązań jest zastosowanie korporacyjnej magistrali usług - ESB (ang. Enterprise Service Bus). W niniejszym artykule scharakteryzowano funkcje i zastosowania, przy integracji aplikacji, narzędzi ESB.

This article presents a brief overview of enterprise service buses (ESB) with the key aspects of their usage in application integration. An introduction to application integration using service oriented architecture is presented. Expected functions of ESB are shown. Finally two open-source ESB implementations are described: Mule and ServiceMix. Examples of simple business processes implementations using both products are included.
