What is enterprise mash-up?

If the mashup is an enterprise mashup, it means that its creator intends it to solve a particular business problem. Then, tight coupling between provider and consumer software would be a serious concern.

Enterprise mashups strives to meet business needs, therefore, will require SOA, and the SOA infrastructure necessary to guarantee loose coupling. Without that loose coupling, mashups are little more than toys from the enterprise perspective.

Within enterprises, mashups provide an easy way to visualize data that is spread across the enterprise. Technologies like Ajax have made it easy to build rich and powerful clients by bringing together data from inside and outside enterprises.
