What Is Enterprise Computing?

Enterprise information is the information gathered in the ongoing operations of an enterprise-sized organization

Business intelligence: Includes several types of applications and technologies for acquiring, storing, analyzing, and providing access to information to help users make sound business decisions

Business process managementIncludes a set of activities that enterprises perform to optimize their business processes, such as accounting, finance etc.

Business process automation

Provides easy exchange of information among business applications, reduces the need for human intervention in processes
