Hi Pavani,
Just a brief introduction.Rest you can find with forums and sdn.
SOA is service Oriented Architecture. To make/expose/define your business or requirements in terms of services so that they can be reused.
Previous architures were tightly coupled. SOA is loosely coupled.
ESOA is SAP concept with same as SOA or we can can say that derived from SOA where services have only business semantics. In short, they are indentifying services on a coarse granular level which are meaningful only for business. They have named it as Enterprise SOA.( eg create purchase order)
Technology--> though RFC,EJB etc are also part of SOA but Web services due to its great interoperatibility among different languages and platform is mainly used.
Hope this helps.

Piyush

The question is how is SAP's offering of SOA different form other vendors.
The biggest differentiator are the Enterprise Services themeselves.
SOA is about composing or decomposing a business process from or into services. To achieve the right granularity in services is an art and not everybody can master that art. It will take a lot of business knowledge and experience to understand the various business processes and identify the right "Granularity" in these services. SAP along its partners with the 30+ years of experience across businesses and solid knowledge of business processes has developed a methodology to discover these enterprise services.
This is one of the biggest differentiating factors in the SOA game - a pool of enterprise services of the right granularity to address the fast changing business environment. No other SOA offering has this advantage and this is one advantage that cannot be copied or replicated easily.
Hope this helps,
