Answer 1

Answer:

Map can use the value as key.

Answer 2

Map can used to store value as Key.

Explanation:

• A key-value store, also called a key-value database, is a simple database with an associative array as its primary data architecture, with each key corresponding to one and only one item in a collection. This form of relationship is known as a key-value pair.
• Each key-value combination has an arbitrary string as the key, such as a filename, URI, or hash. Any type of data, such as a picture, a user preference file, or a document, can be used as the value. The value is saved as a blob, which eliminates the need for data modelling or schema creation up front.
• Because the value is stored as a blob, there is no need to index the data to increase efficiency. Because the value is opaque, you can't filter or control what's returned from a request based on it.
