This paper provides a brief review of several papers, articles to know about the background of column oriented database. In this paper, we study the method for implementing column-store on top of Row-store in PostgreSql along with successful design and implementation. Performance results of Column-Store are presented, and compared with that of Row-store results with the help of TPC-H benchmark.
