Redis is an in-memory database, which means it Store data in your computer's memory rather than on a permanent storage device such as a hard drive. This makes Redis very fast as it can access data quickly without having to wait for the hard disk to read or write.

Although Redis is not a relational database management system (RDBMS), such as MySQL or PostgreSQL, it does provide database-like functionality, such as:

• Data storage: Redis can store various data types, including strings, hash tables, lists, sets, and ordered sets.
• Data query: Redis provides a powerful query language that allows users to quickly find and retrieve data.
• Transaction processing: Redis supports transactions, allowing users to perform multiple operations atomically and consistently.

The following are some common Redis usage scenarios:

• Caching: Redis can be used to cache frequently accessed data to reduce database load and improve Application speed.
• Queue: Redis can be used as a queue, allowing applications to store tasks in a first-in-first-out (FIFO) or priority manner.
• Session Management: Redis can be used to store user session information, such as shopping cart contents and access counts.
• Leaderboard: Redis can be used to track leaderboard data, such as the highest score in a game.
