The combination of PostgreSQL and PostGIS provides a robust database platform that supports the integrated management of both geospatial data and attributes associated with those data in a database system that is supported by a large number of client applications, including GIS and mapping applications. PostgreSQL is an open source object-relational database server that implements the Structured Query Language (SQL) for database design, management, and use. PostGIS is an implementation of the Open Geospatial Consortium's "Simple Features Specification for SQL" standard which defines data types and functions that may be implemented in a SQL database for the storage and management of geospatial data within the database.
