Abstract: As we all know that many different kind of organization need database for required information from different area like analytic, different types of reports and other many reasons. As the organization grows the database also grow into millions of records spared over many tables and business intelligent/science. And if any organization want any specific report strategic analysis, and other business intelligence activities for their work need data for many data warehouses where no need to access all the attributes just needed few attributes of a table. This is not possible for traditional DBMS to read and fatch only those attribute which is needed by query. Because as we all know that traditional row oriented DBMS access the data row by row in this process we read that column also those are not needed by the user which cause the time delay for query. In this paper we going to present the need of column-oriented DBMS, architecture design and the working structure of a new type of DBMS which is called Column oriented DBMS also known as read-optimized relational DBMS.in contrasts with most currently used systems, which are write-optimized. Among the differences in its design are: The data can be stored in column rather than row, carefully coding of object into storage including main memory during query processing, storing an overlapping projections, rather than the current fare of tables and indexes, a non-traditional implementation of transaction which include eas
