Nonrelational databases

In a nonrelational database, you create tables. A table is a place where you can store and query data.

Nonrelational databases are sometimes referred to as “NoSQL databases” because they use structures other than rows and columns to organize data. One type of structural approach for nonrelational databases is key-value pairs. With key-value pairs, data is organized into items (keys), and items have attributes (values). You can think of attributes as being different features of your data.

In a key-value database, you can add or remove attributes from items in the table at any time. Additionally, not every item in the table has to have the same attributes. Example of data in a nonrelational database:

1.Name: John Doe
Address: 123 Any Street
Favorite drink: Medium latte

2. Name: Mary Major
Address: 100 Main Street
Birthday: July 5, 1994
