Vertica is a high performance commercial column-oriented DBMS that runs mainly in a Clustered environment. It uses ANSI SQL and runs on Linux.
Vertica is a column-oriented DBMS designed for data warehousing. Vertica is based on C-Store, which was an academic project involving academic and entrepreneur Michael Stonebraker (a co-founder of Vertica, Ingres, VoltDB) and colleagues from Brandeis University, Brown University, MIT, and University of Massachusetts Boston.
Vertica is designed to run in a Clusters environment on Linux boxes. A Vertica Cluster runs in a MPP(Massive Parallel Processing)fashion, and it is designed to scale linearly by adding nodes to the cluster. Columns are stored independently of other columns and allow for increased compression in storage.
