A simple thought on Redis database

There are several data types in the Redis database:

String, hash, list, collection, ordered set

The scenarios they apply are as follows:

String usage single, used to store the value of a key for one by one corresponding occasions

List as an array to use

For hashes, it is particularly useful for storing objects. For example, for object-oriented thinking, key can be used as the object name, field as the property name, and value as the content of the property

A collection has a nature of de-weight, and a simple set is used for a different member of a key.

An ordered set can be used in some cases where data size is sensitive. For example, key as the object name, score as the member's fractional value, member and other member as members of the same type
