The beginning of the process involves understanding the project requirements. This includes defining functionality, the database, interaction with the frontend, security, and other technical details.
1. Database Design
The foundation of the backend system is the database. Here, tables, relationships, schemas, and data storage methods are defined. Properly designed databases are crucial for the effective operation of the system.
2. Technology Selection
Developers choose technologies and tools for creating the backend system. This includes selecting programming languages, frameworks, development environments, and additional libraries.
3. API Development
Developers create an API (Application Programming Interface) - an interface through which the backend system communicates with the frontend or other applications. Creating different services allows different parts of the system to work independently.
4. Business Logic
Here, the logic for data processing and execution of business processes is built. This can include query processing, data validation, calculations, and other operations.
5. Security and Access Management
Developers ensure the security of the system. This includes managing user rights and access, protection against malicious attacks and vulnerabilities, data encryption, and other security measures.
6. Testing and Bug Fixing
Once the system is built, various types of tests are conducted - functional, integration, unit, etc. This helps discover and fix errors and misunderstandings before the system goes live.
