System integration services in internet era

摘要

Information systems are an important factor in ensuring that enterprises remain competitive in the global competition era. They must be able to be developed rapidly and maintained easily. Openness, the most important characteristic of opensystems such as UNIX, often prevents people from developing such systems rapidly and efficiently. It is therefore necessary to restrict. to some extent, openness in system integration using open systems.On the other hand, it is also necessary to apply new technologies such as Webtop-based thin-client to the integration In the Internet era, times passes three times faster than previously. This means that systems must be developed three times faster aswell. Development periods could be shortened through minimizing programming work by increasing software reusability with framework technology.
