Optimizing grocery delivery routes using Oracle APEX, Oracle Autonomous Database and Google Maps APIs
In this special edition of APEX Office Hours, we will be joined by Santhosh Jose, who is a Principal Applications Engineer in the Oracle HCM product development organization. During the pandemic, Santhosh volunteered his time to help deliver groceries to the elderly. After delivering groceries a few times, he quickly realized that the list of addresses were not as efficient as they could be. This is the classic "Traveling Salesman" problem in computer science ( ) - what is the shortest possible route between a list of destinations?

To solve this problem, Santhosh turned to Oracle APEX & Oracle Autonomous Database to help solve this problem. In a short amount of time, Santhosh built a fully functional "Route Builder" application, which, given a list of addresses, will help determine the most efficient route between those addresses. To facilitate navigation by a driver, Santhosh also integrated Google Maps.

This session will be comprised of two parts - an introduction and background of Santhosh Jose and how he found Oracle APEX, and then a description, explanation and demonstration of the RouteBuilder app.
