Question

a) Parent table
b) Document database
c) Key/value database
d) Child table

Answer 1

Non-relational databases, also known as NoSQL databases, include types such as document databases and key/value databases, which are designed for varied data models and rapid scalability.

Step-by-step explanation:

Non-relational databases, also known as NoSQL databases, are designed to handle a wide variety of data models, including large volumes of fast-changing structured, semi-structured, and unstructured data. The main types of non-relational databases include:

• Document database: Stores data in documents similar to JSON (JavaScript Object Notation) or XML objects. Each document can have a different structure.
• Key/value database: Stores data as a collection of key-value pairs, where a key serves as a unique identifier to access its corresponding value.

Options 'a' Parent table and 'd' Child table are concepts tied to relational databases, which organize data into tables with predefined relationships, not non-relational or NoSQL databases.a
