Vectorwise

Vectorwise is an SQL relational database management system designed for high performance in analytical database applications.〔(【引用サイトリンク】 Vectorwise Enterprise )〕 It holds the records as top performing database on the Transaction Processing Performance Council's TPC-H benchmark for database sizes of 100 GB, 300GB, and 1TB on non-clustered hardware. It held those records since March 2011.〔(【引用サイトリンク】 TPC-H - Top Ten Performance Results - Non-Clustered )
Vectorwise originated as the X100 research project carried out within the Centrum Wiskunde & Informatica (CWI, the Dutch National Research Institute for Mathematics and Computer Science) between 2003 and 2008, and was released as a commercial product in June, 2010.
A version released on 5 June 2012 was available for 64-bit Linux and Windows platforms.
==Technology==
The Vectorwise architecture makes use of "Vectorized Query Execution" involving the principles of vector processing and single instruction, multiple data (SIMD) to perform the same operation on multiple data simultaneously. This allows the database to reduce overheads found in traditional "tuple-at-a-time processing" and exploit data level parallelism on modern hardware, with fast transactional updates, a scan-optimised buffer manager and I/O, and a compressed column-oriented as well as traditional relational model row-oriented storage.〔
