- APIs, or Application Programming interfaces, bridge the front-end and back-end, allowing for smooth communication.
1.3. Database
The database stores and manages information, ensuring smooth application functionality. Some popular database management systems include:
- Relational databases (SQL): The best options for applications using well-structured data are MySQL and PostgreSQL.
- NoSQL databases: MongoDB – More flexible, ideal for handling unstructured data like social media content.
1.4. Server & Operating system
This is where the application is hosted, processed, and operated, including:
- Server operating systems: Linux, Windows.
- Cloud hosting services like AWS, Azure, and Google Cloud provide fantastic scalability, top-notch security, and a dependable infrastructure for your applications.
1.5. APIs serve as the connection between the front-end and back-end
An API, or Application Programming Interface, acts like a bridge allowing different parts of an application to communicate. For example, in e-commerce, when you place an order through an app, the API quickly transfers data from the user interface to the server, kicking off the transaction process.
To build a high-quality application, it’s essential to understand what a tech stack is and how various technologies work together. Choosing the right tech stack ensures your project runs smoothly, remains easy to maintain, and can scale as needed over time.
