14.5.2 PostgreSQL

PostgreSQL is a surprisingly complete and full-featured database offering.

Not only does it fully support stored procedures, triggers, views, foreign keys, and transactions, but it also implements an innovative “record versioning” system for multiuser integrity. Unlike many other databases, readers may con- tinue to read consistent data during writing activity (nonblocking revisions), and backups may be taken while the database is still available for queries. This is a serious database.

This database has excellent public documentation. Take a look at the PostgreSQL Documentation.1 Another useful book is PostgreSQL by Korry and Susan Douglas (ISBN 0-7357-1257-3).
