PostgreSQL is a powerful, open-source, object-relational database system. It’s popular around the world, given its strong reputation for reliability, feature robustness, and performance. In this course, Janani Ravi dives into advanced topics in PostgreSQL. After showing how to install and set up PostgreSQL, Janani shows you how to work with geospatial data, which allows you to specify geographic objects such as locations, lines, and polygons, all on a geographic map, and also supports location-based queries like distance computation and area computation. Next, learn about performing full-text search operations, and how to work with triggers, which let you set up an automated execution of a function when a certain type of operation is performed. Finally, Janani explores transactions, which allow you to bundle multiple steps into a single, all-or-nothing operation.
