# 5 Layers of Software Development 5 Layers of Software Development 1. **UI (User Interface) Layer This is the user's interaction point with the software.** * Technologies: HTML, CSS, JavaScript, Tailwind, ReactJS * Purpose: Crafting an intuitive and engaging user experience. 2. **API (Application Programming Interface) Layer Defines how different software components should interact.** * Technologies: REST, GraphQL, SOAP, NodeJS, Postman * Purpose: Facilitating communication between the UI and the backend systems. 3. **Logic (Business Logic) Layer Contains the core functionalities and business rules of the application.** * Technologies: Python, Java, Spring, C#, .NET * Purpose: Implementing the logic that drives the application’s functionality. 4. **DB (Database) Layer Stores and manages the application’s data.** * Technologies: MySQL, Postgres, MongoDB, SQLite, CouchDB * Purpose: Ensuring data is stored securely and can be efficiently retrieved and manipulated. 5. **Hosting (Infrastructure) Layer Encompasses the infrastructure where the software runs.** * Technologies: AWS, Azure, Google Cloud, Docker, Kubernetes * Purpose: Providing a reliable and scalable environment for the application to operate. By understanding and properly implementing these layers, teams can build robust, scalable, and maintainable software systems. FYI: technologies will vary depending on the tech stack. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
