Key-value stores
Key-value stores are a type of database that organize data using pairs of keys and values. Think of it like a digital locker: each key is a unique identifier, similar to a locker number, and the value is the information stored inside that locker. This allows for quick and efficient access to data, as you can retrieve the value by using its key. Key-value stores are often used in applications where speed and scalability are essential, such as caching user sessions or managing simple user preferences in web applications. They are fundamental in many modern software architectures.
