Non-Relational Databases Overview

What are Non-Relational Databases?

Non-relational databases do not use the rows/columns table format of relational databases. They have different and varying frameworks of storing and modeling data. By relaxing certain rules these databases provide increased scalability and availability. The term “non-relational database” is sometimes used synonymously with NoSQL databases. Document-oriented databases, key-value databases, object databases and graph databases are non-relational databases.


Non-relational databases grew in popularity due to their ability to meet the aggressive scaling needs of web applications appearing on popular websites (e.g. social media). They also are suited to support Big Data applications with their high throughput of unstructured data. Non-relational databases can also store data in memory for persistence, to more easily read this fast-moving data. Finally, popular non-relational databases are open source and present little or no upfront cost, and no licensing fees.

Non-Relational Database Features & Capabilities

Notable capabilities and advantages of non-relational database are:

  • Can be purpose-built to specific data models

  • “Tableless” and opaque data storage

  • Can manage unstructured or multi-structured data

  • No need for a predefined schema

  • Better manage abstract data

  • Support graph data modeling

  • Support document-oriented data store

  • Less strict consistency (e.g. eventual consistency) models

  • Better operational performance

  • Require fewer computing resources

  • More horizontal and vertical scalability

Pricing Information

Many non-relational databases are open source and available free without a license. Non-relational databases also provide more flexible data center budgeting. Adding or removing servers need not create downtime. Scalability and availability are their greatest advantages. Non-relational databases can also be deployed across cheaper, commodified servers relative to their RDBMS counterparts.
