Open Database Connectivity (ODBC) remains one of the most widely used APIs for database access, enabling applications to communicate with various database systems through a standardized interface. When working with PostgreSQL, the ODBC driver provides a crucial bridge, allowing tools like Microsoft Excel, Tableau, Power BI, and custom applications (written in C#, Python, or VB) to connect seamlessly. and custom applications (written in C#
