Supported CRUD operations for all Entities

Hi CRM Team,

I was searching for the CRUD operations supported for all the CRM Entities.
From the following reference link: msdn.microsoft.com/.../mt607901.aspx , I could only find out sample example about Account entity.

I have couple of queries:
a) Is there any documentation available for the rest of the entities?
b) Is there any tabular data as to which Operation is applicable for each Entity?

Thanks and Regards,

Rajinder Singh
