There are four main types of NoSQL database data models that include key-value stores, document stores, wide-column stores, and graph databases. Provide a brief description of each
What will be an ideal response?
Key-value Stores consist of a pair of a key and related collection of values. The key-value store database allows one to access information based on an a key. Redis is the most popular key-value score database on the market.
Document Stores typically use standard formats such as JSON to access and modify contents of a document based on its structure. Similar to key-value stores, documents stores also access data based on a key.
Wide-Column Stores consist of rows and columns and distribution of data is based on the use of both (rows and columns) to access data. Each row is allowed to have a different column structure, something that is not possible in an RDMS.
Graph-Oriented Databases are designed to maintain information regarding relationships between data items. This data is stored in nodes with properties and connections between the nodes which represent relationships.
