What Are The Various Layers of A Mobile App Architecture?

Mobile app development architecture usually consists of three layers:

• Presentation Layer
• Business Layer
• Data Layer

1. Presentation Layer

The presentation layer contains all processes and components that are required for displaying the app to the consumer. When creating a presentation layer, the focus is on what users are seeing and how they will be interacting with the app. This layer is based on UI and UX. Therefore, it is directly related to users- 

• User Interface(UI): It refers to design components like colors, fonts, location, and general layout. Gaining a clear understanding of the target demographic and distinct user personas is necessary to build a user interface.
• User Experience(UX): It relates to how a user engages with the app, like buttons, sliders, multimedia(video and audio), etc. The display layer approach within mobile app development is guided by this knowledge. All components are selected in this manner. 

While creating this tier, mobile app developers need to select the appropriate platform and iOS type to ensure compliance with standards.

2. Business Layer

This layer contains the reasoning and rules that govern data interchange, operations, and flow regulation. It includes the fundamental processes, business logic, etc. It is also in security, data caching, authentication, logging, and exception handling. 

Based on the app’s operations, it can reside on the user’s device or the server. The business layer offers solutions to issues like-

•  What is the issue which your app is trying to solve?
• How does this app deliver the solutions to the users? 
• How does it differ from current competitors in the market?

3. Data Layer

This layer, as its name suggests, includes all data tools, service providers, and data access elements that facilitate data transactions. This layer is divided into two sections-

• Persistence: API data access to data sources
• Network: A network connection, routing, and also fault reporting

Important Things To Consider During Mobile App Development Architecture

A crystal clear mobile app architecture is necessary since it accelerates the development process. Developers can also regulate data flow inside the application. It enhances application quality and makes it more efficient.

The app of every layer of a three-layer model is decided by its function. It is determined by the display designs and their actions. Moreover, the following considerations are essential for designing and building mobile apps-

1. Type of Device

When creating a mobile app, you need to select among three platforms, Android/Windows/Cross-platform. Next, check the various smartphone types in use that are numerous. These are major pieces of information for deciding the optimal dimensions for development. 

Here are some important considerations that you need to share when building a mobile app-

• DPI and screen size
• Display resolution
• CPU processor type
• RAM size

The main aim at this stage is to offer the best experience possible across all platforms and device sizes, including smartphones or tablets, so that each user, regardless of device choice, offers the optimal experience.

2. Frameworks

Development frameworks are taken into consideration when creating a mobile app architecture and establishing the tech stack. App development frameworks offer libraries, basic templates, and components to construct both front-end and back-end web projects. 

Bootstrap, Backbone, Vue, or React are some front-end frameworks for developing mobile apps. Back-end(server-side) development frameworks are determined by the programming language and target platform used, which include Ruby on Rails, Xamarin, Flutter, Swift, etc. 

2.1 Bandwidth Possibilities:

User research is necessary for learning details related to the potential user. Users across the glove face varying bandwidth constraints, with some countries using 5G while others are still suffering from patchy connectivity. A highly dynamic, graphic-heavy app, for instance, isn’t suitable for apps that target customers based in rural areas.

3. UI/UX

For mobile app architecture, app design is necessary for both initial impressions(UI) and retaining users(a strong UX).  A good user experience(UX) design is necessary for an online business. However, UX also includes varying user requirements and best practices for each OS and device.

During the design process, the mobile app architecture must harmonize with both UI and UX. For guaranteeing that the app is offering value, to guarantee that the app is offering value, start by learning the fundamentals of smartphone UX design and also the latest UX design trends. Consider including user feedback throughout the development process to improve the app’s overall experience.

4. Navigation

The user’s immediate interaction with the design is via the navigation, which affects simultaneously the front and the back end. A good mobile UX design simplifies it for designers to navigate the website and discover other parts. Navigation requires a high level of familiarity. 

Below are the best practices for navigation to the ease of use of the mobile app, reducing friction in the user journey-

• Hamburger Menu(three-line menu): Due to its familiarity, the hamburger menu in the navigation top bar is popular among mobile apps. It minimizes clicks by enhancing navigation with a mouse over the menu
• Search: A well-paced search bar enhances usability, and the usual location is the top right. 
• Buttons/Bars/Drawers/Tabs: There are different ways to browse around in an app, like fixed bars of buttons, vertical bars, drawers(secret navigation), and tabs(filtered data with set titles).
• Conventional Icons: Home, search, images, folders, and other recognizable symbols make navigating easy.
• Functional Labeling: It helps to differentiate information by spelling out the objective of a button, choice, or function. 
• Site Organization: Classification can make website navigation either simplified or complicated based on how sections are called and structured. 
• Gestures: It allows hand motion navigation and can help to speed up navigation.
• Scrolling: Scrolling refers to the way the app supports scrolling vs fixed items.
