Data structure with key and value

What is a key data structure?
A key in the context of data structures (such as in the book CLRS) is a value (often an integer) that is used to identify a certain component of a data-structure.
Often, keys determine how the underlying data is stored or manipulated..
What is a key-value store data structure?
Key-Value Databases.
Key value databases, also known as key value stores, are database types where data is stored in a “key-value” format and optimized for reading and writing that data.
The data is fetched by a unique key or a number of unique keys to retrieve the associated value with each key..
What is the data structure of a key-value store?
A key-value pair is the fundamental data structure of a key-value store or key-value database, but key-value pairs have existed outside of software for much longer.
A telephone directory is a good example, where the key is the person or business name, and the value is the phone number..
Which data structure has key and value?
HashMap is a data structure that uses a hash function to map identifying values, known as keys, to their associated values.
It contains “key-value” pairs and allows retrieving value by key.
Map myhash = Collections. synchronizedMap(hashMap);.
Which data structure has the feature of key-value pair?
A key-value database (also known as a key-value store) is a type of noSQL database.
Unlike prior relational databases that stored data in defined tables and columns, a key-value database instead uses individual or combinations of keys to retrieve associated values.
Together they are known as key-value pairs..
Which data structure would you use to store a list of keys and values?
A hash table is a data structure that is used to store keys/value pairs.
It uses a hash function to compute an index into an array in which an element will be inserted or searched..
Which type of data structure requires key-value pairs?
A key-value database is a type of non-relational database, also known as NoSQL database, that uses a simple key-value method to store data.
It stores data as a collection of key-value pairs in which a key serves as a unique identifier..
A hash table is a data structure that is used to store keys/value pairs.
It uses a hash function to compute an index into an array in which an element will be inserted or searched.
Key-value databases (also called key-value stores) are non-relational databases that store unstructured data.
In a key-value database, data is stored using a collection of data pairs, commonly known as key-value pairs — where the key serves as a unique identifier, and the value contains the data payload.

A key–value database, or key–value store, is a data storage paradigm designed for storing, retrieving, and managing associative arrays, and a data structure more commonly known today as a dictionary or hash table.
