What Is An Enterprise Business Service? |
|
Answer» An Enterprise Business Service (EBS) is a first-class OBJECT exposed on the enterprise service bus. An EBS is coarse-grained and performs a specific business activity or task and is either an Activity Service or Data Service. For example, the activity it performs could be one of the FOLLOWING: Creating an account in a BILLING system. Checking for the presence of an account in a billing system. Getting the balance details for an account from a billing system. An EBS is agnostic to a specific back-end implementation. Back-end implementations that support EBS interface STANDARDS can be considered service providers. EBSs expose coarse-grained, message-driven interfaces for EXCHANGING data between applications, both synchronously and asynchronously. The salient features of EBSs include: Reuse of available assets in the Oracle portfolio. Substitution of a service provider with another without any impact to the client. Content-based selection of the service provider. An Enterprise Business Service (EBS) is a first-class object exposed on the enterprise service bus.
