Column-Oriented Databases to Gain High Performance for Data Warehouse System
Column-oriented database systems, also known as column-stores, have an important demand in the past few years. Basically, it is about storing each database column separately so that the attributes belonging to the same column would be stored contiguously, compressed and densely-packed in the disk. This method has advantages in reading the records faster as compared to classical row stores in which every row are stored one after another in the disk. These databases are more suitable for data warehousing system to get analysis done faster as data is stored in columnar form.
