The PostgreSQL 9.1 open source database offers users new features including some that are not duplicated with any other vendor.

Database Journal brought this news to our attention in their article, “PostgreSQL 9.1 Advances Open Source Database Innovation.” Being the leading proprietary database is a new position for the PostgreSQL team, but the innovation included in this release moved them up in the pecking order.

PostgreSQL 9.1’s new features include Serializable Snapshot Isolation (SSI), a feature that keeps concurrent transactions consistent. Another example is the K-Nearest-Neighbor Indexing feature, which provides fast text-search queries.

Indexing is a great feature in any document management system and it helps to reduce redundancy, but it is very important to choose a product that makes your content findable – easily and with thoroughness. Access Innovations is one of a very small number of companies able to help its clients generate ANSI/ISO/W3C- compliant taxonomies and associated rule bases for machine  assisted indexing.
