Authorization specifies which features or data a verified user can interact with, according to their permissions or role in the application.
2. APIs (Application Programming Interfaces) : define how different parts of an application communicate, allowing the front-end and back-end to exchange data and perform functions seamlessly.
3. REST API : follow a set of conventions using HTTP methods like GET, POST, PUT, and DELETE, enabling simple, stateless, and scalable interactions between clients and servers.
4. GraphQL : provides a flexible alternative to REST by letting clients specify exactly which data they want, reducing unnecessary data transfer and improving performance, especially in complex applications.
5. Session management : the practice of tracking and storing user activity across requests. It ensures that users remain logged in and their interactions are remembered as they navigate through an application. This is crucial for maintaining a seamless and personalized user experience.

Types :

1. Relational databases (SQL) : store data in structured tables with rows and columns, using keys to link related data. They are ideal for complex queries and ensure strong data consistency, with examples like MySQL, PostgreSQL, and SQLite.
2. Non-relational databases (NoSQL) : use flexible schemas, storing data as key-value pairs or documents. They handle large, dynamic datasets well and are suited for real-time or scalable apps. Examples include MongoDB, Firebase, and CouchDB.

Key Concepts :

1. CRUD operations : store data in structured tables with rows and columns, using keys to link related data. They are ideal for complex queries and ensure strong data consistency, with examples like MySQL, PostgreSQL, and SQLite.
2. Data modeling : involves designing the structure and relationships of data within the database to ensure it is organized, consistent, and easy to access, which helps maintain application efficiency and scalability.
3. Indexes : improve database performance by enabling faster data retrieval, allowing queries to quickly locate relevant records without scanning every entry, which is crucial for handling large datasets.
4. Joins/Relations : connect multiple tables based on shared keys to combine related information efficiently, while NoSQL databases handle relationships through document references or embedded data, supporting flexible data structures.

Tools :

1. MongoDB Compass : is a visual tool that helps users explore and manage MongoDB databases through an intuitive graphical interface, making it easier to view, query, and analyze data without needing complex commands.
2. pgAdmin : is a powerful web-based administration tool for PostgreSQL that provides an easy way to manage databases, run queries, and monitor performance through a user-friendly interface.
