This document describes how to connect to a PostgreSQL database from ASP code and perform basic CRUD operations. It includes code snippets for: 1. Creating an ADO connection object and defining the connection string to connect to a PostgreSQL database on localhost. 2. Including the connection code on other pages and using it to populate a dropdown from a database table. 3. Examples of using the connection to run INSERT and UPDATE SQL statements to add and modify data in database tables.
