Build Custom Maps in Mobile Apps


In an earlier post we described how to integrate maps into cross-platform mobile apps with each end-user device’s native map application. Our example app generated a map with pins locating major airports in the United States. Illustrations showed maps generated by the same app on an Android phone, an iPhone, and Windows desktop.

What if a list of locations to be mapped is not known in advance, but generated based on user activity at run-time? MobileTogether, the low-code cross-platform mobile development tool from Altova, also empowers developers to build custom maps in mobile apps on the fly based on a list of geolocations generated at run time.

XPath & XQuery Tutorial for SQL Pros (Video)


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.

UML Modeling for C++ with UModel


C++ is one of the most powerful and efficient programming languages available, the de facto choice for high-performance computing, server applications, and complex architectures that demand the most powerful language constructs. The Unified Modeling Language™ (UML®) is the standard to design, visualize, and document models of software systems implemented in C++ and other source code languages.

Altova UModel competes with even the most advanced UML modeling tools with complete code engineering support in UML modeling for C++. UModel includes: C++ code generation from UML diagrams, reverse engineering C++ code to generate UML models, and round-trip engineering to update revisions to either C++ code and UML models.

Model transformation even lets developers convert an existing UML model designed for Java, C#, or Visual Basic to support C++.

Working with Avro Big Data in Your Favorite XML Editor


Big Data trends have developers working with XML alongside other data protocols such as JSON and Apache Avro, and XMLSpy supports both of these with dedicated editing views and functionality.

Let’s see how specialized Avro support in XMLSpy makes visualizing and searching Avro files, as well as editing Avro schemas, uniquely easy. We’ll also look at some of the advantages of utilizing RaptorXML Server for high-performance Avro processing.

Handle HTTP Errors During Automated Data Integration


Data analysts and other professionals often need to generate real-time data through automated execution of data mappings that request Web services and save the results. During automated execution it’s important to gracefully handle any unexpected HTTP error rather than terminate the integration task.

In an earlier post we discussed conditional processing of a REST Web service response to handle HTTP errors, where separate output files were generated for a normal response and an error. Now let’s look at a revised mapping solution for the airport status example to generate a single mapping result file that contains either the requested airport status or a description of the error.

Top 5 Requirements for RMAD Tools


Originally coined by analyst firm Gartner, RMAD (rapid mobile application development) isn’t just the biggest acronym in app development for 2019 –  it’s an absolute necessity.  Waiting six to eight months for an app ensures that it will be completely obsolete once it’s finally ready for prime time: requirements will change, another app will fill the niche, or end users will already be entrenched with another solution.

In addition, a traditional, non-RMAD approach assumes you have a team of mobile developers ready to tackle the project, and for many businesses, hiring experienced app developers is a lengthy, expensive process. Outsourcing your app development work that well, either. Many have tried, but few have succeeded in getting third-parties to realize the original vision of the app, on time, and while ensuring the integrity of their intellectual property rights.

Luckily, with the increasing prevalence of RMAD tools, developing a sophisticated, full-featured app in a week or two – and with your existing tech team – is suddenly a reality. Of course, not all RMAD tools are created equal. Let’s take a look at the five top requirements you should demand in an RMAD solution.

Integrate Maps into Mobile Apps


Developers can create highly-customized location-based apps by leveraging geolocation functionality in mobile devices. Now MobileTogether, the cross-platform, low-code mobile development tool from Altova, supports deep integration of maps into applications for all popular mobile platforms.

Developers can integrate maps into mobile apps, add dedicated markers, and define custom actions based on user clicks on the map. For instance, an enterprise might want an app to include a map of all branch office locations, then display the current inventory when an office is clicked.

In a previous post we described a mobile app designed to let users check the status of major US airports by selecting an airport code from a combo box. An alternate technique would be to replace the 47 combo-box entries with pins on a map.

Let’s look at this example.
