Don’t Click Submit Twice!!!

Speaker:

Michael L. Perry

Abstract:

You are losing orders. You are double-charging. And as a result, you are losing customers. When your customer sends in an order, make sure that it gets to your back end. Make sure that it gets processed once. Make sure that it gets shipped once. And, most importantly, make sure your customer gets billed once.

The typical web application is not built with durability in mind. It leaves open several small holes where data could be lost or duplicated. I’ll show you how to recognize those holes. I’ll show you tools and techniques to close those holes.

In this talk, we will see:

  • Durable page design
  • Message-driven architecture
  • Service bus
  • Distributed transactions

Follow these guidelines, and you will keep your customers. Even if they click Submit twice.

Bio:

Software is math. Michael L Perry has built upon the works of mathematicians like Bertrand Meyer, James Rumbaugh, and Donald Knuth to develop a mathematical system for software development. He has captured this system in a set of open source projects, Update Controls and Correspondence. As a Principal Consultant at Improving Enterprises, he applies mathematical concepts to building scalable and robust enterprise systems. You can find out more at qedcode.com.
