Working with the PostgreSQL relational database

One of the most popular open source relational databases is PostgreSQL. This case study shows how to connect to a PostgreSQL database and how to explore and visualise both the data and structure. The demo implements two approaches to work with the data from the database.

The PostgreSQL client in GToolkit is called P3. It is augmented in GToolkit in various ways.


The necessary code for the demo including all its dependencies can be loaded using the following expression.
