Hello Ahmed,

Before knowing Enterprise services you must understand web services, i have detailed below with some information for you to get some idea, hope it helps you to some extent.

<b>Web services</b>

&#56256;&#56452;Open standard for system interaction independent of technical architecture

&#56256;&#56452;Self-contained, self-describing, modular functionality

&#56256;&#56452;Once deployed, applications and other Web services can discover and invoke a Web service

<b>Enterprise services</b>

&#56256;&#56452;Web services that provide business functionality

&#56256;&#56452;Have enterprise quality in scalability, robustness, security, manageability, supportability …

&#56256;&#56452;Web services model describes what functionality can be expected from those services

For Example: Cancel order

&#56256;&#56452;Order can usually not be simply deleted in a database

&#56256;&#56452;Cancel ordermay involve a complex business process

&#56256;&#56451;Back-end system

---Roll-back of order possible?

---Manual steps in roll-back process necessary?

&#56256;&#56451;Who else is involved and needs notification?

&#56256;&#56451;Logistics service

&#56256;&#56451;Loan service

&#56256;&#56451;Bonus program

&#56256;&#56451;Stop approval process?

&#56256;&#56451;Cancellation fee applicable?

<b>Therefore Functional services are needed to build a true Enterprise Services Architecture (ESA)</b>

Web services ensure interoperability between platforms.

ESA creates business benefits by separating business semantics and logic from system semantics and logic, providing the business analyst with the services needed to build a composite application.

Award points accordingly,
