To Jim Dominilsque

Jim wrote the forewords of the Second Edition of my book on the ERP Systems. When I'm reading again what he wrote in 2002, I realize that he was propheticizing the major technical rupture that is coming with the "Cloud Computing". In the next few years, these systems will progressively migrate to the Clouds... but where? On the cumulus,the stratus or the nimbus? Hope it will not be on the cirrostratus nebulosus: I can hear Jim laughing in his rocking chair just behind Saint Peter!

 " When Jean Louis asked me to write the forewords of the second edition of his book, my instant positive answer was hiding clearly many groundless fears. First, the subject itself, in a book written in French, scarcely sounded propitious for easy reading. Second, computer scientists used acronyms, which do not tell much about what is precisely behind technologies used. Third, I am still suspicious of those gentlemen who have developed such smart systems… while forgetting to manage correctly some calendar’s events, like September 9th , ’99 or 01-01-00…Therefore, I was wondering a lot about the partiality of the non-computer scientist’s eye about such a subject. Peculiarly, an express mail company delivered the book to me on the 20-02-2002, the very day of my 77th birthday, which is a rare palindrome correctly processed by Information Systems; At least, as an 8-digit coded date of the Christian calendar. My decision was to devour it in half a day, while I was idly lying down on my deckchair, in the shade of the shivering palm leaves over my head. It was midsummer, in a breezing sunny afternoon, twelve feet from the rustling wavy waters of New South Wales sandy shores. I found the book is easy to read for an English-speaking retiree of 77, who understand fairly well informal French! However, it does not comply with the lower figure of the motto used by the cartoonist portraying a daredevil Belgian fair-haired boy, who claimed his readership to be youngsters from 7 to 77.

More seriously, Jean Louis shows, through the issues of applications integration that today, each cell making up any commercial enterprise may use dedicated applications specializing in its core business but, completely contributing to the entrepreneurial management objectives. Therefore, the integration of all these Application Systems is an unavoidable constraint for a rational management of the company. This was true from the moment men operated computers as management devices. However, should we still use the word “integration”? The notion of API, Application Programming Interface, is almost obsolete, while the EAI, Enterprise Application Interface systems are today the leading edge of the market! The real evolution is the one, which drove our communities from engineering Computers Collaboration by Interfacing Systems closely; to designing Data Share by Interconnecting Networks openly. Now, it is time to re-engineer Business Communications by Internetting Objects loosely! This book shows this advancement very well. Another important issue of Application Integration is developing concurrently functional models and technical architecture for composite systems running different generations of technologies such as legacies, ERP systems, Web Applications. This book is certainly the only one, both in the French and English technical literature to show both sides of the solution.

Just one more word : I looked through the book for the most repeated acronym… and for the time reading, I became “The Old Man and the SEA” (System, Enterprise, Applications)…
