PostgreSQL Data Engine

The world's most advanced operating system.
The world's most advanced open source database.
The Mac's most advanced dental practice management software.

PostgreSQL is a powerful, open source relational database system. It has more than 15 years of active development and a proven architecture that has earned it a strong reputation for reliability, data integrity, and correctness.

It is highly scalable both in the sheer quantity of data it can manage and and in the number of concurrent users it can accommodate. There are active PostgreSQL systems in production environments that manage in excess of 4 terabytes of data.

Best of all, PostgreSQL's source code is available under the most liberal open source license: the BSD license. This license gives you the freedom to use, modify and distribute PostgreSQL in any form you like, open or closed source.

The time tested and proven use of PostgreSQL made it a logical choice for professional environments, hence a logical choice for MacDent Pro.
