Mobile app architecture: components and factors

Today, due to the development of the mobile industry sector, companies have the opportunity to increase their businesses’ value by implementing mobile applications. But until you get a successful application, it is important to focus from the beginning on its architecture. Building clearly defined mobile app architecture it’s not an easy process, it heavily relies on a very meticulous plan, just like building a city. Due to this, you’ll save time, stress, effort, money because ahead a well-designed app’s architecture makes it easier for you to modify, test, and debug.

ARCHITECTURE …? WHAT IS THIS?

Being more explicit related to app architecture, we can define this as a roadmap and a detailed guide app of how the mobile app is supposed to be created. It consists of structural elements and interfaces, connections between selected elements, the general style of the program, and several layers, including:

Presentation LayerBusiness LayerService LayerData Layer
contains UI elements along with the parts processing them.consists of workflows, business entities, and components.is made up of service interfaces and message types.involves data utilities, data access components, and service agents.

Once you have decided to create an application, invest time and money in its architecture. Focus on its convenient functionality, rapidity, safety, and excellent structure. Firstly, start by checking key principles that a mobile app architecture should include:

  1. Efficiency. The application performs the assigned tasks and performs the functions in any conditions. The system is efficient, reliable, and can handle all loads.
  2. Flexibility. The solution you choose is easy to change and there are fewer mistakes. You can change one element, and this will not be fatal to other components.
  3. Extensibility. You can add as many features as you like to your application if required.
  4. Scalability. Development and addition time is reduced. A good architecture allows you to streamline development into multiple parallel threads.
  5. Testability. You are able to test each component separately, to allow future consistency to diverse variables.
  6. Manageability. You monitor the workability, functionality, security, and efficiency of the system.
  7. Reusability. The elements and structure can be reused in other projects.
  8. Maintainability. Due to market conditions and consumer behavior continuous changes, architecture should always have the capacity to be changed, corrected, modified, and improved.
  9. Comprehensibility. The code should be understandable to as many people as possible. A lot of people are working on the application. A good architecture allows beginners to quickly understand a project.
  10. Performance. Ensure quick response to users’ intent/request during app usage. Therefore, we provide amazing customer satisfaction, without resorting to the app uninstalling and customer loss.
  11. Security. The architecture should be maximum robust to fully secure and protect user data and data which is used by the app.

Then, based on the target audience, platforms it’ll be deployed on, features and functionality, correctly choose the right type of your mobile application:

  • NATIVE APP

is a program for iOS, Android, and other platforms. Native means the app is built for one platform.

+ efficiency due to compliance with all the requirements of the selected category of devices;

+ more secure;

+ has better performance as compared to a hybrid app;

+ interact with other native APIs;

+ doesn’t depend on plugins and WebViews;

+ perform much faster as compared to a hybrid app;

+ quick access to new features;

+ better user engagement;

– two separate codebases and databases – one for Android and the other one for iOS;

– require installation;

– difficult to run SEO campaigns and strategies;

– costs (time/budget).

  • HYBRID APP

a site optimized for use on a mobile device.

+ reduce development time and costs;

+ leverage cross-platform capabilities;

+ work on multiple platforms;

+ less time-consuming to create;

+ automatic updates;

+ easy maintenance;

– requires a constant Internet connection, because it is located on a separate server in the network.);

– limited user interface;

– depend on the browser’s speed.

and:

  • bandwidth scenarios;
  • user interface;
  • navigation methods;
  • the device types:
ANDROID APP ARCHITECTUREiOS APP ARCHITECTURE
For the Android mobile architecture app, a good solution is the Clean Architecture because it makes your app more independent of frameworks, databases, layers, and more. In other words, your developers will not be tied to a specific framework or database. Also, we use, MVVM, MVP, MVI.

Deciding architecture type, pay heed to android frameworks, libraries, app developing concepts, app components, and fragments to provide an ideal approach and an outstanding user experience.
For iOS, you may find suggestions from Apple to use the MVC (Model-View-Controller), MVVM architectural pattern for UIKit, but again, you need to understand and carefully analyze every detail to realize which kind of architecture will make the best version of your app.

We at DAS Solutions design mobile applications using the following methods, depending on the project objectives:

MONOLITHIC ARCHITECTURE

The necessary logic is stored on the server, and all the necessary information for the server is stored in the database. Such applications are very simple and require relatively little development time. But in the long run, applications are bound to change because they have to fit new platforms, gadgets, and operating systems.


MICROSERVICES ARCHITECTURE

This is typical for cloud-native applications, which are now popular due to the advantages that cloud environments provide for business. It is a method of building independently developed and distributed applications, each of which runs as one or more isolated processes.


For any changes, even the smallest, monolithic applications require rebuilding and deploying the entire monolith. Whereas microservices are broken down and placed independently of each other. This means that microservices offer a completely independent approach, with each individual component performing a different function for the entire system to work.


SERVICE-ORIENTED ARCHITECTURE

SOA is independent of the programming languages, platforms, or protocol specifications used for services developed. Also, an important aspect of SOA is high flexibility, which is achieved due to the ability to quickly adjust business logic – a change made to a business function will eventually affect all the necessary applications.


With the increasing complexity of applications, some modules are moved to separate hardware parts and services. Modules here sometimes hold their own databases and reside on separate devices. This has its pros and cons.
Such an architecture requires serious investments at the start, but with a competent approach, costs are reduced at subsequent stages of development. Service-oriented architecture is good for large companies.


Before developing your mobile app architecture, consider some important factors and elements like:

Device Types

  • Screen resolution;
  • Screen size;
  • CPU Features;
  • Storage Space;
  • Memory;
  • Availability of the development framework.

✓ Bandwidth Scenarios

  • with an internet connection (3G, 5G);
  • offline connection.

✓ Navigation Methods

  • Stacked navigation bar;
  • Navigation bar (top and bottom);
  • Tag driver;
  • Modular controller;
  • Single view;
  • Scroll view;
  • Gesture-based navigation;
  • Search-driven navigation.

✓ User Interface (UI)
✓ Real-Time Updates vs Push Notifications

It might look difficult to plan the architecture app, and it is we confirm, this is why we recommend to work with an expert software development company.

DAS’s architects are experienced and qualified specialists who work in tandem with programmers, coming with advice to developers related to the app and giving instructions on how to create an app. At the same time, the architect is looking for compromises between customers, managers, developers.

We know how to create a fast and reliable architecture, providing a unique user experience. Designing mobile applications is our specialty. Contact us by email and let’s speed up your mobile app architecture.

    The danger of legacy

    Today, software development takes place in a highly competitive environment. This introduces several significant risks that may affect business performance and one of the most dangerous is excessive efforts to maintain legacy technologies. Although businesses may be hesitant to make investments in new technology, the true cost of legacy technology far outweighs the investment. Because legacy applications cost more to run and maintain, they make the business highly inefficient, increases operational costs and system downtime. Legacy technologies are also extremely vulnerable, because many of these outdated systems are no longer supported by the manufacturer. Another problem with using outdated technology is that most legacy systems are incompatible with newer systems.

    Risks

    However, scrapping legacy systems and replacing them with more modern software involves significant business risks. Most managers try to minimize risks and therefore do not want to face the uncertainties of new software systems. Replacing a legacy system is a risky business strategy for a number of reasons. There is rarely a complete specification of the legacy system. The original specification may have been lost or not written in sufficient detail. Therefore, there is no straightforward way of specifying a new system that is functionally identical to the system that is in use.

    New software development is itself risky so that there may be unexpected problems with a new system. It may not be delivered on time and for the price expected.

    Keeping legacy systems in use avoids the risks of replacement but making changes to existing software usually becomes more expensive as systems get older. There are several reasons that lead to an increase in the complexity of system maintenance. First of all, different parts of the system may be implemented by different teams. There is, therefore, no consistent programming style across the whole system. Replacement of developers is a completely normal business process, but it is necessary to strictly adhere to the code style and follow the architecture guidelines.

    Optimization

    To eliminate the risk of obsolescence of a programming language or framework, it is desirable to divide the application into separate services with a minimum number of dependencies. If necessary, any of these services can be rewritten using new technologies and this will in no way affect the functionality of other parts. In addition to dividing into separate services, the use of modular architecture and the CQRS principle allows you to divide functionality within a service.

    During the development process, it is necessary to allocate time for creating and updating the documentation so that it does not become outdated. All documentation should be structured and it is advisable to use specialized tools for writing and storing documentation. All business processes should be described in the form of UML diagrams.

    The system may have been optimized for space utilization or execution speed rather than written for understandability. This causes particular difficulties for programmers who have learned modern software engineering techniques and who have not been exposed to the programming tricks that have been used. In the long run, clear and easily modifiable code is always preferable to an optimized but overcomplicated solution.

    Adherence to uniform standards, division into independent services, timely updating of documentation allows you to gradually develop the product without the need to rewrite it completely.

      How to Meet IT Project Deliverables?

      At DAS Solutions we often work with our partners on creating a project plan and project-related documentation. One of the first things we do before starting the project is discuss the IT project deliverables.

      A deliverable is an item produced as a part of the project. As the project moves forward, deliverables are further defined and specified. Deliverables can be tangible or intangible. For example, if you need to implement a system that tracks orders, your key deliverables will include tangible (the system itself) and intangible (training sessions for employees) items.

      The most important thing to do to meet the IT project deliverables is to define them.

      Clearly stated deliverables will help you see the project strategically. Once the deliverables are identified, they serve as a foundation for the success of the project. That is why it is crucial that project managers take enough time to gather and analyze all relevant information.

      The deliverables need to meet the following criteria:

      • Have a detailed and clear description for all team members involved in the project;
      • Specify the operations and functionalities that will be performed by the software;
      • Ensure alignment with all requirements provided by the customer;
      • Clearly establish the client’s expectations;
      • Secure the client’s consent and acceptance;
      • Serve as a measurable basis for deliverables’ testing and review.

      Keep the documentation updated

      Updated documentation written clearly will help avoid any confusion. Make sure that all those involved in the project have a copy or can easily access it, because everyone has to be on the same page. Efficient coordination of the information will ensure that the deliverables are met.

      Master the management of IT project deliverables

      • Assign your team tasks that have a work result. It can be a short script that allows to add new items in the bag, or it can be something more complex such as user manual.
      • Be clear about task delivery intervals. A specific date stimulates the team member to focus on the result. At the same time, don’t set too broad intervals, for example a month or two months.
      • Monitor and record the progress of larger deliverables. If something goes in the wrong direction you will be the first to notice. This will give you the opportunity to come up with a different plan.
      • Implement a formal acceptance and review procedure, this will help you avoid misunderstandings.
      • Gather a dedicated responsible team of developers and encourage knowledge-sharing between them. In case someone decides to move to a different project, you need to ensure that all deliverables for your project will be completed on time.
      • Don’t make assumptions. If something does not seem clear enough, discuss it with the team members and the stakeholders.  It is better to spend 30 minutes on making sure that there are no ambiguities left than to spend hours on re-working.

      When you have a reliable and professional partner it is an exciting process of meeting project deliverables.

      We recommend reading the guide on how to build a software development project plan as well.

      Top Features of an Effective Claims Management System

      Claims are a critical part of the insurance business. Even if your insurance company is not as big as Axa or Allianz, you need to have an efficient claims management system. Clients’ mindset and expectations are different from what they were 10 years ago. A recent survey called Insurance 2020: The digital prize — taking customer connections to a new level  has brought to light some fascinating facts:

      1. 71% of consumers made an online research before buying an insurance product.
      2. 68% of respondents were willing to download and use an app from their insurer in order to access services.
      3. 50% (!) stated their readiness to additional personal and lifestyle information so they can get the best deal for insurance services.

      Insurance must thus move quickly to become more customer-centric and to improve customer experience. For successful communication, your customers and team members need to have access to an intuitive claims management system. In this post, we’d like to highlight some features that would be welcomed by both your customers and your staff.

      Features of a claims management system appealing to customers:

      • A simple submission process from any device

      Users need to have the possibility to complete a short and simple form using their smartphone or tablet. Claimants’ basic info, such as first name and last name (as well as other contact information) should be  filled in automatically when the customer decides to submit a claim. This should be easy to do since the info is already in the carrier’s database. In addition, the claims process will be easier if customers understand intuitively how to attach photos of receipts or invoices to their claim.

      • Tracking claims progress

      Claimants need to be able to track the status and decision of consultants regarding their claim, further steps they have to take, as well as the final outcome.

      • All documents in customer’s pocket

      When the customer uses their insurer’s app, they need to store their paperwork such as copies of their ID, driving license and policy documents on their application.

      • Online claims payments

      Clients can save a lot of time if the transaction of claims can be done online. It also adds transparency to the process because both the customer and the consultant have access to the final decision of the claim.

      • Simplicity and security

      For fast and easy access one can log in with a PIN code that is easy to remember. Any claims information entered must not be lost until submitted. At the same time all personal data must be secured via encryption. It is also useful if most of your app’s features are available even if the user is offline.

      Your team will thank you for the following claims management system’s features:

      • Reminder function

      This is a useful feature because it enables a consultant to stay on top of the tasks that require a timely response. The reminder feature facilitates the service provided by the insurance company.

      • Handling different types of contracts

      It is preferred that the claims management system can handle various types of standard contracts. Furthermore, as the clients and the consultants might introduce amendments to the conditions of the standard form of contract it is critical that the system is able to deal with changes.

      • Keeping documentation up-to-date

      Some claims are more challenging to prepare because more documentation is required. Thus claims managers need to have a system to help them keep an up-to-date documentation, prepare the claims, and prevent them from losing relevant documents.

      • Extended search capabilities

      The agent needs to have the possibility to search virtually any data within the claim, including claimant, address, policy number, phone number, check number, etc. This function makes searching easier.

      • Centralized database

      If you have several offices across the country it is better to have a centralized database so that the management can have access to the files, templates for claims and any other information. A reporting tool will help them analyze the outcome and status of claims.

      So here we are! Ten features that a claims management system should have to improve your company’s performance. All in all, the app has to address your customers’ and your employee’s needs, which is why it is so important to choose a system with a user-friendly interface that fits well with your specific needs. Contact us and lets custom build it for you business. 

      Moving Forward,

      Ways Automation Can Improve Your Business Processes

      Continuously changing market conditions, high speed in decision-making, multitasking in asset management and the need to reduce risks require modern approaches to the work processes within any business. It allows you to free up precious resources for strategic planning and concentration of management in key areas of the company. Business automation is the partial or complete translation of repeatable, time-absorbing operations and business tasks under the control of a specialized system. As a result, you get to increase productivity and effectiveness of strategic management.

      Automation is usually conducted in two ways:

      – Automation of the basic business processes: for example, sales management or work with clients. In this case, it is carried out to directly increase the volume of sales, the number of products produced and increase the profitability of the entire business as a whole.
      – Automation of supporting processes, such as accounting, reporting, records management. Such automation does not directly affect the increase in revenue, but helps reduce the time and costs of daily work execution.

      The main tasks of business automation are the following:

      – effective support of operational activities of the enterprise, control and organization of accounting
      – preparation of any documents for partners/clients, including invoices, bills and business proposals
      – quick receipt of reports on the state of affairs in the company for any period of time
      – optimization of staff costs, increasing the efficiency of working hours by freeing employees from routine/habitual work
      – minimizing the negative impact of the “human factor” on the most important business processes
      – secure storage of information and data
      – improving the quality of customer service

      Automation of business processes can significantly improve the quality of management in the company and the quality of its product. For the enterprise as a whole, it gives a number of significant advantages like:

      – Increase the speed of processing information and solve repetitive tasks
      – Increase business transparency
      – Increased coherence of staff and the quality of its work
      – The ability to control large amounts of information
      – Reducing the number of errors and improving management accuracy
      – Simultaneous resolution of several tasks
      – Rapid decision-making in repetitive situations

      As a result of automation of the business processes – the management receives much more information for analyzing business processes in the form of detailed analytical reports and is able to direct the company qualitatively taking into account external and internal indicators.

      Core Functions of a Custom Insurance Software System

      In today’s competitive environment, an insurance software system should connect your business to the most advanced technologies and prevent you from staying behind the competition. Moreover, it should be easy to use and maintain, able to withstand all your requirements, and be easily expandable with a modular design so that new functionalities are easy to integrate. Old systems are no longer sufficient as a result of unprecedented volume of operations; consolidation is needed to get businesses more agile.
      Challenges & Issues
      The main two issues of the industry are related to cost savings and compliance with legal regulations. 
      1. Manual processes and the paper-based documents are costly and unwieldy, slow and prone to errors.
      2. In addition, they are hard to manage and difficult to comply with risk management guidelines and directions.
      A custom piece of software can be focused on improving the entire process by:
      • Eliminating paper, redundancy and errors.
      • Hosting and integration of transaction-based or the collaborative processes.
      • Adopting compliance standards across the organization.
      • Shortening workflows.
      The overall benefits of a custom solution:
      • Lower cost of processing the loan.
      • Processing multiple loan files without a proportional increase in staffing.
      • More efficient processes – eliminate duplicates, improve service performance.
      • The person processing the request can access all the files as needed – this means providing an overview of the client – both for data and for documents.
      • The possibility to grow the business without the need for additional storage spaces, which can be costly.
      • Protecting the goods and information in accordance with the storage and maintenance policy on a single platform of the entire content (email, enterprise data, records, photos, etc.), a useful function in audit cases, based on a common model of security.
