What are the s-party concept? What is there siginificance?

Siebel brought the concept of Party Model which refers to instance of entities that have access to records of "Person Related Entities" "Organization related entities" and "Grouping created to access data".

When i meant Orginization related entites are Accounts postition division and Orginization when meant by Person related entites was Contact employee user and Partner when meant by Grouping accesscontrol means "Access Group and User list"

s-party concept was introduced to help the business layer communicate in the uniform way.

For eg earlier if s_org_ext communicated with s_org_ext thru foreign key primary key relationship. like this there were many objects like account contact etc.etc which became more complex to handle so siebel came withe the concept of s_party which act as a central table to all the party table so all the party data is stored in s_party which acts as a central medium for communications.
