In a comparison of NoSQL and SQL, which database should you choose?

Author Kamil Zawadzki Managing Partner
What is a database? A database is a structured collection of data. It organizes information in a manner that allows for easy access, management, and updating. This concept of databases dates back to the 1960s when the need for efficient data storage solutions first arose. Various types have emerged with the increasing demand for databases, notably SQL (Structured Query Language) and NoSQL databases. At some point, every application or website creator will need to choose between these options, depending on their specific requirements. The decision hinges on the nature of the data being handled and the desired functionality.

What is SQL?

"SQL" stands for Structured Query Language, a standardized language for managing and manipulating data within a database system.

Databases such as MySQL, PostgreSQL, and MS SQL, known as relational databases, utilize relationships to connect pieces of information across multiple tables. This method ensures data is organized naturally and logically, with a well-defined structure. SQL databases handle consistent data over time, such as customer information in online stores, including names, order types, or usernames. This data remains static until an update is necessary. The efficiency of SQL databases lies in their ability to avoid duplication by linking data through relationships. For instance, using a customer ID to reference data in related tables allows for easy retrieval of specific information without replicating it in multiple locations.

Key features of an SQL database include:

SQL databases are among the most commonly used in the market. They excel in systems focused on transactions, such as managing customer relationships, utilizing accounting software, or encompassing e-commerce. These databases provide a reliable framework for handling data's structured and relational aspects within these contexts.

What is NoSQL?

NoSQL databases, alternatively known as non-relational or distributed databases, offer a distinct approach to data management compared to traditional SQL databases by not enforcing rigid relationships among data points. Key features of NoSQL databases include:

NoSQL databases excel in scenarios requiring unstructured or semi-structured data analysis, providing a practical solution when data characteristics are likely to change unpredictably. This makes them a preferred choice in dynamic environments where the limitations of traditional SQL databases could introduce significant complications.


The most popular database services

Several web services on the market aim to streamline database configuration and scaling, offering ready-to-use database systems that facilitate information organization. Among the most popular are:

These services are designed to reduce the complexity involved in database management, allowing developers and businesses to focus more on their core activities and less on the technical intricacies of database administration.


Deciding between SQL and NoSQL databases hinges on numerous vital considerations. Firstly, assess the sector your business falls into: does it lean towards analytical work, or is it predominantly transactional, necessitating a rigid structure and complex query capabilities? The nature of your data and the type of scaling that best aligns with your needs are also critical to evaluate. Ultimately, there's no universal solution that fits every scenario. The choice is entirely dependent on your specific requirements and circumstances.
