Message Brokers allow the information flow between applications. Following this type of middleware, we advance to an integration architecture that is based on message brokers. As the applications universe grows and the Point-to-Point architecture is no long a viable option, the necessity of middleware is obvious. One of the possible architectures to implement the middleware […]

In the last chapter we introduced the notion of middleware, why we need it and how it turns integration easier. So today we are going to talk about the different types of middleware. And let us start with one vert used in point-to-point integration: RPCs (Remote Procedure Call) Middleware RPC exists since the 1970s and […]

For years, information systems have been built as “stovepipes” [1], creating monolithic self-contained applications that have not been designed for integration with other applications. These systems were built with very specific requirements and not using standard data storage and application development methods [2]. However, even years after its implementation, they continued to be critical although […]

Today’s applications integration is of great concern for organizations. Due to the large flow of existing information, an increasing specialization of the applications and the great speed at which it is necessary to implement the various requirements that allow organizations to continue to operate successfully, it became crucial to create mechanisms for quickly make the […]
