Columnar Database or Column-Oriented Database - definition(s)

columnar database or column-oriented database - A database that stores data by column rather than by row. In a row-based database, a row might contain a name, address, and phone number. In a column-oriented database, all names are in one column, addresses in another, and so on. A key advantage of a columnar database is faster hard disk access.
