Tools for the Project Lifecycle: Build Phase (UI)
Blog|by Julia Hopkins|25 August 2020
Having covered project collaboration and the design phase in my two previous blogs, I will now look at tools to assist developers during the build phase. This phase involves the creation of code for the different tiers of the application. These are the user interface (UI), business logic layer and the data layer. The UI is sometimes referred to as the presentation layer although the latter shouldn’t be confused with the OSI networking model layer 6. When I refer to an n-tiered architecture, I’m referring to the various parts of the application rather than the physical model, although the two are closely aligned. A tiered view of the application provides a convenient way to divide things up when considering third-party tools for the build phase.
A small project might have a single developer working on all tiers but a more complex project might have a team dedicated to a single tier. Most IDEs such as Microsoft Visual Studio and Embarcadero RAD Studio provide all that’s needed for the entire application. Third-party tools tend to focus on a specific tier and add value over and above the basic tooling provided by the IDE. This is particularly true of the client-side UI which I’ll cover in this blog. My follow-up blog will cover third-party tools for the data access layer.
Delivering the best possible user experience
An intuitive and well-designed UI is critical for the efficient working of the application and there are many examples of third-party vendors that provide cross-platform components for this. These allow you to build richer UIs with greater functionality and a consistent look and feel which improves operational efficiency and helps reduce training overheads. Typical examples of components include radio buttons, icons, calendars, charts and data grids. As third-party components are designed to work with specific platforms, I’ll digress at this point to detail some of these.
For Windows desktop applications, there are a number of different platforms that include a UI framework complete with ‘out of the box’ UI controls.
Universal Windows Platform (UWP) uses XAML to separate UI from the business logic code. It’s suitable for desktop applications that require a sophisticated and customisable UI. It also provides access to the Windows Runtime (WinRT) APIs.
Windows Presentation Foundation (WPF) and WinForms are both .NET platforms for managed applications with a lightweight UI model and access to both .NET Core and full frameworks. These are forms-based with a large collection of drag-and-drop controls. Like UWP, these frameworks have deep integration with Visual Studio which has benefits for developer productivity.
Win32 is the original platform for native C/C++ Windows apps that require direct access to Windows and hardware. The Win32 API is the platform of choice for apps that need the highest level of performance and direct access to system hardware.
WinUI is the native UI layer in Windows. WinUI 3 is the next version of the framework. It will ship later this year for all types of Windows apps from Win32 to UWP.
The n-tier model applies to desktop and web applications although the technologies differ. In the case of a web app, the UI content is served up by a browser while the mid-tier logic is handled by the likes of ASP.NET or Node.js, to name a few examples.
In addition to the Microsoft and Java programming platforms discussed above, there are other code environments which require tools for the presentation layer. Embarcadero’s popular RAD Studio has its own Visual Control Libary (VCL) for its Delphi Object Pascal IDE. RAD Studio also ships with the FireMonkey GUI framework used by their Delphi and C++Builder IDEs for cross-platform applications. These target Windows, macOS, iOS and Android devices.
Several vendors specialise in providing tools for the UI and they cater for most, if not all, of the desktop and web environments described above, as well as mobile. Progress Telerik is one of these. For Windows desktop apps, they provide 140+ controls for both WinForms and WPF and 20+ controls for UWP. They also have a preview edition for Microsoft’s latest WinUI. For web apps, their Java UI components cover jQuery, Angular, React and Vue. For Microsoft technologies, they provide ASP.NET components for MVC and AJAX implementations as well as .NET Core projects. Other platforms are catered for too, with products for Blazor, Silverlight, Xamarin, PHP and JSP.
Infragistics and GrapeCity are two other vendors that specialise in these components. Like Telerik, they also cover most of the main platforms described above with their Infragistics Ignite UI and GrapeCity ComponentOne products for web, desktop and mobile apps.
Components for specific requirements
Some vendors specialise in certain types of components. The Chart FX tools from SoftwareFX are designed to provide desktop, web and mobile apps with grids, charts and data visualisation capabilities. For data analysis, Chart FX provides tools for OLAP, statistical analysis, conditional attributes and more. The tool’s data population methods include passing data directly through the API, Resultset binding, XML files, collections, arrays, text files and crosstab.
There are many other examples of components for specific purposes such as barcode readers, spell checkers, chat etc that are part of the application’s client-side. Other technologies also play a part in generating a good UX although not all are specifically GUI components. For example, Aspose is a leading vendor of cross-platform APIs and SDKs for handling file formats and rendering images. Mapping technologies such as Bing Maps and HERE Technologies are also playing an increasing role in both web and desktop application front-ends.
