An ESB Implementation for Airport Environment

Today companies have to deal with the problem of improving their services by providing new functionalities, due to customer requests, marketplace needs and rapidly changing technologies. Old systems can’t be fully replaced because they represent a reliable resource on which companies are still basing their core-business, so there is a need to extend companies’ functionalities without changing all or some of their applications. In an airport environment, this is also true because airport systems need to communicate among themselves with little or no change. An Enterprise Service Bus (ESB) is an emerging software architecture that provides a communication and integration paradigm, in which a set of heterogeneous applications become able to communicate among themselves. In this paper, we discuss the architecture of our ESB implementation, which is suited for application integration in the airport environment.
