1. Strings: Redis strings are binary safe and can hold any data such as a text string, an image, or a serialized JSON object. They can be used for simple key-value storage, counters, or caching.
2. Lists: Redis lists are ordered collections of strings that allow for adding or removing elements from either end of the list. They can be used for tasks such as implementing a messaging system, task queues, or logs.
3. Sets: Redis sets are unordered collections of unique strings. They are useful for tasks such as tracking unique visitors to a website, implementing social graphs, or tracking user preferences.
4. Hashes: Redis hashes are collections of key-value pairs where the keys and values are strings. They are useful for storing and retrieving complex data structures such as user profiles, product information, or configuration settings.
5. Sorted Sets: Redis sorted sets are ordered collections of unique strings, where each string is associated with a score. They are useful for tasks such as implementing leaderboard systems, top-N lists, or ranked search results.
