Hi Teja,
While Webservices is based on SOAP protocol , OData is based on REST and Atom Protocol .
Consumption using Webservices would be tedious task and would need lots of efforts , You need to prepare XML request and response and While in OData , the URL purely takes care of everything.
You just need to build the underlying Entity Models and implement runtime classes
OData is widely accepted and in SAPUI5 the consumption of an OData service is at ease just by invoking the URL, while the same consumption using a webservice requires lots of implementation effort.Since Odata is light weight and can be used for CRUD operations
The Links shared by Aswin are good and read through them would give a nice insight
Best Regards,
Lakshman.
