6. • A key feature of the architecture is the use of
• Enterprise Service Bus (ESB) that enables a smooth
communication between the applications.
• The business processes of the enterprise may be exposed as
services that can be classified as follows:->

across the enterprise in various data sources.
• 2:Integration services that provide the ability to interact with
