When to use the NoSQL Database vs. SQL Database 

In this article, we will discuss when to use the No SQL database and what are the used cases for the same. SQL isn't the quickest or most elegant way to communicate with databases, but it's our best. Why is that? 

Structured Query Language is now the industry standard for altering and querying data in relational databases, but some solutions have proprietary extensions. Because of SQL's simplicity and ubiquity, numerous "NoSQL" or non-relational data stores, such as Hadoop, have adopted parts of SQL or created their SQL-like query languages. 

 
 
 
 
 
 
 
 

However, SQL was not always the “universal” database language. SQL had several disadvantages from the start (around 1980). Many researchers and developers at the time believed that SQL’s overhead would prevent it from becoming useful. Many academics and developers, including myself, at the time, thought that SQL’s overhead would prevent it from ever being used in a production database.

What are the used cases of the NoSQL database ? 

 
 
 
 
 
 
 
 
 

Choosing between a SQL and a NoSQL database is not always easy. Each has its advantages and disadvantages to deal with. Making the best decision is dependent on your organization’s unique data environment, as well as your present demands and long-term objectives. Many development teams employ both in their cloud data architecture and, in some cases, within the same application, deploying each to cover the areas they excel at. 

 
 
 
 
 
 
 
 
 

What are some examples of non-relational use cases? Here are a few examples of where NoSQL is useful :-

 
 
 
 
 
 
 
 
 

  • Identity verification and fraud detection 
  • Management of inventory and catalogs 
  • Customer experience, personalization, and recommendations 
  • Sensor data and the Internet of Things 
  • Payments and financial services 
  • Asset management and messaging logistics 
  • Systems for managing content 
  • Media and digital management

When to use the NoSQL database?

 
 
 
 
 
 
 
 
 

Please take a look at the common reasons why it is adapted.  

 
 
 
 
 
 
 
 
 

  • With NoSQL databases, development can be significantly faster than with SQL databases. 
  • A NoSQL database can more readily handle and evolve the structure of many different types of data. 
  • A SQL database cannot handle the amount of data in many applications. 
  • SQL cannot handle the volume of traffic and the requirement for zero downtime. 
  • Can be supported by new application paradigms more simply.

NoSQL database vs. SQL database

 
 
 
 
 
 
 
 
 

The following are the five critical distinctions between SQL and NoSQL :-

 
 
 
 
 
 
 
 
 

  • Relational databases are SQL, while non-relational databases are NoSQL. 
  • SQL databases have a specified schema and use structured query language.  
  • SQL databases scale vertically, but NoSQL databases scale horizontally. 
  • NoSQL databases are document, key-value, graph, or wide-column stores, whereas SQL databases are table-based. 
  • Finally, SQL databases excel in multi-row transactions, while NoSQL excels at unstructured data like documents and JSON.

Advantages of NoSQL database  

 
 
 
 
 
 
 
 
 

The following are some of the most significant benefits of NoSQL databases: 

 
 
 
 
 
 
 
 
 

1. Data Model

can only store structured data, NoSQL databases are incredibly flexible since they can store and mix any data, both structured and unstructured.

 
 
 
 
 
 
 
 
 

2. Data Model Changes 

can only store structured data, NoSQL databases are incredibly flexible since they can store and mix any data, both structured and unstructured.

 
 
 
 
 
 
 
 
 

3. Elastic Scalability

NoSQL databases can scale to support data growth while being cost-effective. 

 
 
 
 
 
 
 
 
 

4. Maximum Efficiency 

NoSQL databases are designed for high throughput and latency (it is the delay between request and actual response). 

 
 
 
 
 
 
 
 
 

5. Open-source software

NoSQL databases are cost-effective to implement because they don’t require hefty license costs and may run on low-cost hardware. 

Conclusion

 
 
 
 
 
 
 
 
 

Most NoSQL databases feature scale-out architecture, giving a straightforward method to scale to support large data sets and high traffic volumes. A database delivered via a cluster of computers can also automatically expand and reduce its capacity. 

 
 
 
 
 
 
 
 
 

Furthermore, many NoSQL databases may be upgraded, allowing the database schema to be changed.
