Common examples of relational databases include MySQL, PostgreSQL, Oracle, and SQL Server. They are ideal for applications that require complex data relationships and transactions.
  2. NoSQL Databases: NoSQL databases, on the other hand, are non-relational databases that offer greater flexibility and scalability for handling large volumes of unstructured or semi-structured data. Popular NoSQL databases include MongoDB, CouchDB, Cassandra, and Firebase. NoSQL databases are often preferred for modern web applications due to their ability to scale horizontally and handle dynamic data structures.

Querying and Manipulating Data

Whether you are working with a SQL or NoSQL database, you’ll need to learn how to interact with the database using appropriate query languages. For SQL databases, you’ll use SQL queries to perform operations like SELECT, INSERT, UPDATE, and DELETE. For NoSQL databases, the methods for querying and manipulating data may vary depending on the database type (e.g., document-based, key-value, column-family, etc.).

Database Design and Optimization

A critical aspect of working with databases is designing the database schema to efficiently represent and organize the data. Proper database design ensures data integrity and optimizes query performance. Understanding concepts like normalization, denormalization, and indexing is essential for creating well-structured databases.

5. Server-Side Development

Building APIs

Server-side development involves creating APIs (Application Programming Interfaces) that allow communication between the client-side (front-end) and server-side (back-end) of the application. RESTful APIs are the most common approach and follow a stateless client-server architecture. GraphQL is another API paradigm that allows clients to request exactly the data they need and nothing more.

Handling Authentication and Authorization

Securing your web application is crucial. Implement authentication mechanisms such as JWT (JSON Web Tokens) or OAuth, which enable users to register, log in, and access protected resources. Authorization controls what actions users can perform based on their roles and permissions.
