Postgres is an open source object-relational database management system that is available across many platforms. It has a large global community of developers and companies. Postgres began as the Post-Ingres project in the 1980s and was renamed PostgreSQL in 1996 to reflect its support for SQL. It offers advantages like being free, open source, highly reliable, scalable, and extensible. PostGIS adds support for geographic objects to Postgres, allowing it to process spatial data types. pgRouting provides routing functionality on PostGIS databases. The document provides instructions for installing Postgres, PostGIS, and related tools.

14. Spatial database.
• Is a database that is optimized to store and
query data that is related to objects in
space, including points, lines and polygons.
While typical databases can understand
various numeric and character types of
data, additional functionality needs to be
added for databases to process spatial data
types.

• Is an open source software program that
adds support for geographic objects to the
PostgreSQL object-relational database.
PostGIS follows the Simple Features for
SQL specification from the Open Geospatial
Consortium (OGC).
• ArcGIS is the most Prominent user.

16. pgRouting.
• provides routing functionality on a PostGIS
database. Free & open source.
• Added to the set of functions in PostGis.
• The most important function is shortest
path.
