Research for Simulation on the Web System Development Project by utilizing Open-source Software API

The author's main theme for research is the systems design and development on the Web business information systems. Taking a global view of business online systems, the author has taken part in this field for about half a century. However, nowadays this territory has changed extremely in great deal of the world. For instances, business online systems have been drastically connected into the Web systems. Other recent instances are open-source software those are almost all free of charge. Especially one of the big characters on the open- source Web systems is the big scalability in its useful software. On this paper the author has made studies of Web information systems by utilizing open-source software API(Application Programming Interface). And then the author shows some simulation-digest in the synthetic model systems
