Retrieve and Modify Images with MobileTogether


Inevitably mobile developers will need to build an app that needs to interact with their users’ camera and gallery.  MobileTogether Designer makes this task easy by providing a set of controls that allow developers to add this functionality to apps in record time.  The video tutorial below is a continuation of our series aimed at working with databases in MobileTogether; it covers steps needed to solicit images and, if necessary, resize those images to fit a user’s device.

 

 

 

If you’re new to MobileTogether Designer, please take a moment to view the MobileTogether Demos page where we have provided links to additional video tutorials and demo apps.

Querying and Editing Database Records with MobileTogether


The heart of any app is its ability to view and modify bits of data. By using MobileTogether Designer, developers can build apps which show a broad picture of all data and enable users to easily drill down and edit individual records. This video tutorial will guide you through enhancing the Books sample app by adding the ability to view and edit records.

If this is your first time using MobileTogether, please take the time to view both our getting started video along with part one of our series on working with databases in MobileTogether Designer. Each of these videos will help you become familiar with the interface, phraseology, and provide you with techniques to efficiently build mobile apps.

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.

First Comprehensive XQuery Online Training Now Available from Altova


XQuery is an XML-based query language for extracting information from structured and unstructured data, typically – but not limited to – XML format. XQuery is supported by dozens of applications and software tools, and is commonly used wherever XML data is exchanged, consumed, or otherwise processed.

Now Altova is proud to announce launch of the first comprehensive XQuery online training, including the latest features of XQuery 3.1. Altova’s free online XQuery tutorial is available now at the Training and Tutorials section of the Altova Web site.
