The most advanced Open Source database system in the world
Many organizations from large corporations, to government institutions, to small online businesses have implemented PostgreSQL to handle their most valuable data and mission critical applications.
Join the PostgreSQL revolution, and take advantage of:
- Immunity to over-deployment, a problem many proprietary database vendors regard as their #1 licence compliance issue
- Exceptional performance and speed
- Uncompromising reliability
- World-class security
- Flexibility to be extended as required
- Highly scalable design
- Worldwide Independent Software Vendor (ISV) network
- Extensive support options
- Minimal administration requirements
- Low Total Cost of Ownership (TCO)
- ANSI Standards Compliance
With a 16 year development history, one of the strongest development communities in the world, and a global reputation for high quality software engineering, PostgreSQL gets the job done and with no hassles.
