3. What is OData?
OData is a standardized protocol for creating and consuming data
APIs. OData builds on core protocols like HTTP and commonly
accepted methodologies like REST. The result is a uniform way to
expose full-featured data APIs.

4. Isn’t REST enough?
REST Provides a standard request format but it doesn’t expose meta
data and it doesn’t provide a standard response format nor standard
extended data retrieving methods such as filtering , paging , sorting ,
etc.
