Abstract: The volume of data in an organization is growing rapidly. So does the number of users who need to access and analyze this data. IT systems are used more and more intensive, in order to answer more numerous and complex demands needed to make critical business decisions. Data analysis and business reporting need more and more resources. Therefore, better, faster and more effective alternatives have to be found. Column oriented database systems have an important demand in the past few years. These databases are more suitable for data warehousing system to get analysis done faster as data is stored in columnar form. 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.
