Non-relational databases like MongoDB and Firebase offer flexible schemas and are well-suited for document-based or hierarchical data. Choosing the right type depends on the nature of the application.
Designing Efficient Data Models
A well-structured database schema improves performance, reduces redundancy, and maintains consistency. Understanding primary keys, foreign keys, indexing, and normalization is essential when designing relational databases.
In non-relational databases, developers focus on embedding versus referencing documents, optimizing read/write operations, and scaling with replication or sharding. Real-world applications benefit from thoughtful data modeling aligned with expected user behaviors.
Understanding APIs and Communication Between Front-End and Back-End
Application Programming Interfaces connect the front-end and back-end. APIs allow client interfaces to send and receive data from the server securely and efficiently.
REST is a widely used protocol for designing APIs based on HTTP methods like GET, POST, PUT, and DELETE. JSON is often used to transfer data due to its lightweight structure. GraphQL is a modern alternative that allows clients to request only the data they need.
Full-stack developers must be comfortable designing, documenting, testing, and securing APIs. Proper error handling and status codes ensure a consistent developer experience.
Authentication and Authorization
Secure applications require proper authentication (verifying user identity) and authorization (granting user permissions). Understanding these concepts is essential for handling user access.
Techniques include session management, cookies, tokens, and OAuth protocols. Modern applications often use JSON Web Tokens for stateless authentication. Developers must ensure that user data is encrypted, access is controlled, and common vulnerabilities like cross-site scripting or SQL injection are avoided.
Server Management and Hosting Basics
Deploying a back-end service requires an understanding of hosting environments, cloud infrastructure, and server configuration. Developers can host applications on traditional web servers or use cloud platforms.
