What is a columnar database?
by Daniel J. Power
A columnar database stores data tables as sections of columns of data rather than as rows of data. Chapple explains "Columnar databases are a hybrid between NoSQL and relational databases. They provide some row-and-column structure, but do not have the strict rules of relational databases."
