A Bayesian justification for random sampling in sample survey

In the usual bayesian approach to survey sampling the sampling design,plays a minimal role,at best. although a close relationship between exchangeable prior distributions and simple random sampling has been noted; how to formally integrate simple random sampling into the bayesian paradigm is not clear. recently it has been argued that the sampling design can be thought of as part of a bayesian's prior distribution. we will show here that under this scenario simple random sample can be given a bayesian justification in survey sampling.
