This is a process that brings together enterprise computer applications under a common programming umbrella to increase functionality and performance. At its most basic, EAI shares data between applications. EAI can have several purposes. It can link databases, share data, and provide a backup database in case problems arise. EAI can also do data warehousing and data funneling from several databases into one for optimal use. Businesses also use EAI to complete a single business transaction across multiple systems.
