I. Column Oriented Database A column-oriented DBMS is a database management system (DBMS) that stores data tables as sections of columns of data rather than as rows of data. In comparison‚ most relational DBMSs store data in rows.

Introduction “Choosing the right OODB architecture can mean orders of magnitude difference in performance and scalability characteristics rather than a few percentage points as found in relational implementations.” To achieve maximum performance and scalability the most important thing is choosing the right application architecture. OODBs give applications much more direct access to the persistent data‚ so application architecture has much more impact on performance than is the case with an RDB
