From Iteration to Interaction with Type Casting

In software development, efficiency and user experience are paramount. One powerful technique that can help achieve both is the use of type casting combined with iteration.

Docker, Database Servers and Xojo

There are many ways to develop with Xojo and use Database Servers. You might be working on a multi user Desktop Application that stores data in a Database. Or you’re creating a multi user Xojo Web Application that needed to be scaled up to a couple of running instances – and use a Database for data storage. Or maybe you’ve written a mobile application that connects to a Backend REST API – again possibly written in Xojo (e.g. with the open source Express, or with Xojo Web).
