How To Build Your First App


MobileTogether Designer provides a powerful drag and drop interface that allows for incredibly quick cross platform app development. To help developers get started I have produced this video tutorial, which covers the interface and the steps needed to build your first app.

By the end of the video developers should be able to navigate the Designer’s interface and create a basic app that takes user input and performs an action with it at the press of a button. This is the first in a series of tutorials aimed at familiarizing developers with the ins and outs of app development in MobileTogether.

XPath & XQuery Tutorial for SQL Pros


Prior to starting at Altova I had zero experience with both XPath and XQuery. The first task I was presented with was to train myself on both query languages as quickly as possible and produce a concise video tutorial. It was important to develop a thorough understanding of their features and capabilities because both languages are integral to app development in MobileTogether and querying data in XMLSpy. I started with a strong background in SQL, learning XPath and XQuery by building queries first in SQL, and then determining how to replicate them in both query languages.

Learn a New Programming Language this Summer


What better goal to set for your summer than learning a new programming language? Forget the “beach books” this summer and set your sights on diving into a new coding language – but which one should you pick?

As reported by IDC there are approximately 11 million professional software developers on Earth, and around 690 notable programming languages (according to Wikipedia). I would wager a bet there is a staggeringly equal number of places online where you can learn one programming language or another. Whether you are already one of those 11 million coding experts or a newbie to programming, there is a plethora of information out there to sort though.

For the purposes for this blog post, we will certainly look at the world’s most-widely-used programming languages in 2016 (see this IEEE article), but also at important languages for data manipulation and querying, so we’ll discuss: C and its derivatives (C++, C#, and Objective-C), Java, Python, R, JavaScript, Ruby, SQL, and XQuery.

Deciding where to start depends entirely on the kind of development scenarios you have in mind, so we’ve broken things down for you to make it easier. It doesn’t matter if you are a seasoned programmer looking to add a new language to your repertoire or a novice who doesn’t know the difference between C, C++, Objective-C, or C# yet. We have assembled a list of explanations to help you choose which language you may want to conquer next.
