Redis stores data in the form of keys and values.
Value can be any string or hashes or any predefined type
hashes allow you the mapping of key and value pairs. key and value are strings only. So, you can store the object type of data. It is similar to the HashMap data structure in the java language.
That means You can store the value as an object.
For example, In applications, you have a coded user object that contains the id, name, and salary in the program.
to cache users’ data, you can use value as user object in Redis.
