N-Tier Architecture divides the app’s functions into presentation/interface, business/core, and data-handling layers to manage the user interactions using this app, platform, or website. Such architecture solutions use multiple stacked layers to build applications with unique custom needs.

Microservices

Microservices work through .NET Core and additional streaming tools like Redis, RabbitMQ, and Kafka to handle large volumes of data while working with different systems. Our team helps you divide large applications into smaller microservices that grow independently to create a complete system for managing and distributing “heavy” applications. This solution is more cost-effective than other models.

Task:

The Cross Innovation Network (CIN) is a closed CRM application with custom CMS features. It is designed to help businesses streamline their data management and visualize key insights. Built from the ground up, CIN allows users to define custom data sets, invite audiences to contribute, and create meaningful visualizations that optimize decision-making processes. This innovative solution serves businesses in various industries, offering powerful tools for managing resources, boosting operational efficiency, and enhancing customer engagement.

Solution:

Our team developed a robust and versatile platform that supports custom CRM and CMS functionalities. The application allows businesses to define their own data sets, which can be filled out by either internal team members or external users. The platform also offers powerful data visualization tools, dynamic filters for refining data, and a campaign module that allows owners to invite their audience to contribute additional data or provide feedback. Some of the key modules and their purposes include:

  • CRM Module — manages custom data types and allows users to interact with them efficiently.
  • Scout Module — a crawler that finds and parses content based on specific keywords, streamlining content discovery.
  • Action Boards Module — visualizes different datasets in a way that is easy for users to understand and act on.
  • Dynamic Filters Module — reduces the dataset to be visualized, ensuring users only see the most relevant data.
  • Campaign Module — allows platform owners to request data and feedback from their audience, encouraging collaboration and enriching the data pool.
  • Permission System — customizes user access levels, ensuring that each user sees only the data they are authorized to view.

 Notable features

  • Multi-Tenant Feature — the same application can be used for different brands, each with its unique styles and content.
  • CMS Feature — the ability to specify each brand's custom colors, borders, and other CSS styles.
  • Widgets — the ability to define a custom data set for each content type and use it across different app parts.
  • Rating System — custom rating gradation for content types, where users can assign their ratings to each item.

Common infrastructure features

  • Custom logs functionality (ELK/Application Insights)
  • CMS/CRM behavior (client/wizards/management pages)
  • App setup via different wizards
  • User management; Access management; Content type management; Campaign; Action Boards; Explorer; Relation; Tenant management
  • RESTful API approach with Swagger for APIs
  • MVC for most of the pages

Result:

The CIN project delivered a fully functional, multi-tenant platform that allows different brands to manage their operations with unique styles and content. The system’s CRM capabilities, combined with the ability to create visualizations and dynamic datasets, have significantly streamlined the data management process for clients. Additionally, the platform’s ability to support multi-tenant environments means that different brands can customize their experience, offering personalized content to their users while maintaining the core functionality.

Furthermore, the introduction of widgets and a custom rating system has allowed users to interact with the platform more dynamically. The system’s scalability ensures that as the platform grows, it will continue to meet the increasing data demands of its users.

The popular .NET Framework speeds up development cycles using its vast library of pre-built components and tools. Code reusability, modular design, and automatic memory management help .NET developers build quick and efficient applications.

C# Programming Language

C# is one of the most flexible programming languages because it is simple, powerful, and versatile. C# is a modern, object-oriented language that helps to write clean, maintainable code for many powerful features like LINQ, async/await, and lambda expressions. A strong typing system minimizes runtime errors and results in reliable .NET applications. C# seamlessly integrates with .NET Framework.

Visual Studio Integration

Visual Studio is a compelling IDE that consists of IntelliSense, debugging tools, and refactoring code. It is also the official IDE tool recommended for any dot net development company. Thanks to Visual Studio, developers receive a set of tools to enhance their workflow.

Best Practices from Microsoft

The .NET Framework updates help Microsoft teach even experienced developers how to implement new industry standards. Microsoft regularly adds new features to the framework to keep it suitable for today's technology ecosystem.

The TwinCore experts choose to implement custom .NET services because the dotnet stack of technologies is very versatile and applicable to many business niches.

Here is why we leverage .NET technology:

  • Free distribution and open-source platform
  • Flexible, multi-language ecosystem
  • Cross-platform development with smart scalability
  • An ability to create modular apps with quick deployment
  • Cleaner code and focused units due to OOP
