NoSQL: Reasons This is The Best Choice for Your App

As the volume of data continues to grow exponentially, the demand for scalable and flexible database solutions has been on the rise. In this context, NoSQL databases have emerged as a popular alternative to traditional relational databases like SQL. In this post, we will explore the use cases of NoSQL, their advantages, and popular NoSQL DB systems in the market.

Understanding NoSQL Databases

NoSQL databases are non-relational databases that store and retrieve data in a non-tabular format. Unlike SQL databases, NoSQL databases use a wide range of data models such as key-value, document-based, graph-based, columnar, and more. This enables them to handle a large volume and variety of data types, which SQL databases cannot.

“Different databases are designed to solve different problems. Using a single database engine for all of the requirements usually leads to non- performant solutions; storing transactional data, caching session information, traversing graph of customers and the products their friends bought are essentially different problems.”― Pramod J. Sadalage, NoSQL Distilled

NoSQL databases have become increasingly popular in recent years due to their ability to handle big data, which has become a major challenge for many organizations. With the explosion of data sources such as social media, mobile devices, and the Internet of Things (IoT), traditional SQL databases have struggled to keep up with the volume and variety of data types.

Types of NoSQL Databases

There are different types of NoSQL databases, each with its own strengths and weaknesses. Some of the most common types include:

  • Key-value – This type of database stores data as a key-value pair, where the value can be anything from simple strings to more complex data types like JSON objects. Key-value databases are particularly useful for caching and session management, as they can quickly retrieve data based on a key. Examples of key-value databases include Riak, Redis, and DynamoDB.
  • Document-based – These databases store data in semi-structured documents, such as JSON or BSON. Document-based databases are well-suited for handling unstructured data, as they can store data in a flexible format that can be easily modified. MongoDB, Couchbase, and Apache CouchDB are examples of document-based databases.
  • Columnar – Columnar databases store data in columns rather than rows, enabling faster query performance for analytical queries. Columnar databases are particularly useful for handling large volumes of data, as they can quickly retrieve data based on specific columns. Examples include Apache Cassandra and Google Bigtable.
  • Graph-based – These databases store data in a graph structure that allows for complex relationships between data elements. Graph-based databases are particularly useful for handling data that has many relationships, such as social networks or recommendation engines. Examples include Neo4j and OrientDB.

Comparing NoSQL to SQL Databases

NoSQL databases have several advantages over SQL databases, including:

  • Scalability – NoSQL databases are designed to scale horizontally, meaning that you can add more servers to handle an increase in data volume. This makes them particularly well-suited for handling big data, which can quickly overwhelm traditional SQL databases. SQL databases, on the other hand, are designed for vertical scaling, where you need to upgrade the hardware to handle more data.
  • Flexibility – NoSQL databases can handle a wide range of data types, making them suitable for handling data in various formats. SQL databases, on the other hand, require a predefined schema, which can limit their flexibility. This makes NoSQL databases particularly well-suited for handling unstructured data, which does not have a predefined schema.
  • Performance – NoSQL databases offer superior performance when it comes to handling large volumes of data. This is because NoSQL databases are designed to handle data in a distributed manner, which allows them to quickly retrieve data from multiple servers. SQL databases, on the other hand, can slow down as the number of records grows, which can make them less suitable for handling big data.
  • High Availability – NoSQL databases are designed to be highly available, meaning that they can continue to function even if one or more servers fail. This is because NoSQL databases are designed to handle data in a distributed manner, which means that data can be replicated across multiple servers. SQL databases, on the other hand, require complex failover mechanisms to ensure high availability, which can make them more difficult to manage.

hqdefault - NoSQL: Reasons This is The Best Choice for Your App

Overall, NoSQL databases offer a number of advantages over SQL databases, particularly when it comes to handling big data and unstructured data. However, it’s important to note that NoSQL databases are not a one-size-fits-all solution, and different types of NoSQL databases may be better suited for different types of data and applications.

Reasons why NoSQL could be the best choice for your app

🔄 Flexibility

Using a NoSQL database can give your business a lot of flexibility. It makes it possible to quickly adapt to new business scenarios. That’s because there is no imposed structure on the data you store. For example, you may have new variants of an existing product. In order to store the new information, you’d normally need to restructure parts of your system. However, with NoSQL, you can store new types of data without changing your database. On the other hand, a traditional SQL system would require significant adjustments.

📊 Big Data

Big Data refers to huge amounts of data, compiled from various sources. In many cases, the data doesn’t have any obvious connections. When you analyze it, new patterns emerge. This could help you spot profitable trends for your business. Many businesses are already experiencing fast growth thanks to Big Data. Speak to your developer team to see how you can benefit from this aspect of NoSQL. It’s not something you want to miss out on!

⬆️ Scaling

Traditional methods can be quite costly when it comes to scaling. This could hinder the expansion of your business. That’s where NoSQL comes to the rescue. NoSQL has evolved due to the need for database scaling. It’s naturally suited for fast business growth. You can scale without having to pay for expensive hardware upgrades. Of course, you still have to spend some money. But, your expenses will be much lower than modifying a regular SQL based system.

💨 Speed

NoSQL is perfect if you want to have your database set up in a short period of time. It’s also relatively easy for developers. This means you can go from idea to market at a rapid rate. The speed at which your web app is available to the market could be everything. It could be the difference between success and failure. Who wants to wait when you could be making money? If you’re looking for quick feedback from the marketplace, NoSQL is the way to go.

There is another advantage to keep in mind. NoSQL queries tend to be faster than SQL queries. This means your customers will enjoy a better user experience. In the very least, you won’t be lagging behind your competition.

🚫👨‍💻 Reduced need for a database administrator

One of the huge hurdles for a fast-growing business is the cost of working with a database administrator. NoSQL can be managed without spending huge amounts of money on maintenance. As mentioned above, your entire system won’t be affected when you need to make changes. This is by design – the idea is to have minimal need for an admin. This means less downtime for your system as well. Overall, you’re getting a relatively stable, easy to manage solution.
