PostgreSQL: Leader in cost reduction

Abstract

The NTT Open Source Software Center is conducting research and development on the PostgreSQL open-source database management system in order to develop and spread open source software (OSS). Recent advances in the development of PostgreSQL have brought it to a level of usability adequate for commercial systems, and due to its great cost-reducing effects relative to commercial products, it is receiving much attention and even being introduced for core systems. In this article, we introduce new functionality in the latest version, PostgreSQL 9.3, released in September 2013, and outline NTT's OSS development policies. We also introduce the SQL/MED (Structured Query Language/Management of External Data) indexing engine, which was developed by the authors as infrastructure for log analysis and an area for expanding applications of PostgreSQL.
