Answer / Nand Kishor Joshi
A Column Store DB, also known as a Column-oriented DBMS, is a database management system in which data is stored and retrieved by columns instead of by rows. This type of architecture is designed to process large amounts of structured or semi-structured data efficiently for analytics purposes. An example of a column store DB is Apache Cassandra, which uses a partitioning model where each table's data is spread across multiple nodes in a cluster and stored in columns. Each column is replicated based on the replication strategy configured.
