MySQL is Still the Most Popular Database

SQL vs NoSQL: MySQL is Still the Most Popular Database

According to Stack Overflow’s annual developer survey, a staggering 55.6% of respondents ranked MySQL to the most popular database in 2020. However, anyone with database experience would tell you that it’s difficult to truly “rank” a database, and they would be correct. Popularity doesn’t exactly mean the best database for your particular application as each project requires different data storage. This leaves us with the lingering question in our minds: SQL or NoSQL? When it comes to selecting a relational or non-relational database there is no “better” or more “superior” option. Rather a question of how you want your data to be stored, displayed and accessed.

The Basics – What are SQL and NoSQL?

SQL stands for “structured query language.” It is used to access, extract and manipulate data within a database. SQL is commonly used within relational database management systems (or RDBMS for short) as the standard query language for working the data within.
A relational database is when the data is organized by columns and rows in a structured manner that is pre-defined by the user(s) – similar to an excel spreadsheet.

What makes MySQL so popular?

It’s simple. That along with features and scalability are always being improved upon. Here is a simple example of data table creation with a MySQL database.

SQL having been defined, it is easy to imagine that NoSQL simply means “No SQL”. However, it really stands for “Not only SQL”, otherwise referred to as non-relational databases.
NoSQL databases have a fundamentally different structure than that of an RDBMS. The data is unstructured and stored in JSON format. This doesn’t require a predefined schema, unlike the traditional field-record format.

SQL vs. NoSQL – What is the Main Difference?

When it comes down to the main question of whether to use a relational or non-relational database, it’s a matter of how well the data is understood and organized. For instance if there is a product category, item, ID, location, etc, it is much easier to interpret and therefore create a schema for interpreting data. Or perhaps you have some further questions to ask yourself before migrating data to a cloud database.

On the other hand, if a website is collecting many different forms of data like usernames, photos, social posts, videos or blogs, it is much more difficult to properly organize that data, in which a non-relational database will prove to be a better option. That is the main difference – SQL databases require a schema to be created before it can start collecting data. A NoSQL platform allows for unstructured data in which can be later defined.

Core Comparison of Relational (SQL) and Non-Relational (NoSQL) Databases

  • Structure – As stated previously, Relational Databases use a pre-defined schema for which the data is to be organized by. This provides better readability and ease of understanding when it comes to the data, but it is important that users understand how they want their data to relate. Non-Relational databases use a key-value system and don’t require a schema, therefore are much more equipped for handling large, unstructured data that can be later defined, though it can be harder to interpret.

How a company or individual can understand and make use of their data is vital to making strategic decisions. It is important to know the structure in which big data relates.

  • Scaling – Cloud computing is known for its offerings of IaaS, making it a much more resourceful way to scale. When it comes to databases, the difference here is that RDBMS (SQL) use vertical scaling whereas Non-RDBMS (NoSQL) make use of horizontal scaling (Scaling-Up vs. Scaling-Out).  Vertical scaling is the process of adding components like storage, drives, memory or ports to a server, which in modern-day computing can be time-consuming and costly. Horizontal scaling utilizes multiple pieces of hardware that work together as a single unit, giving NoSQL an advantage in accessibility and overall cost for when the resource demand increases.

SQL vs. NoSQL – A Summarized List of Strengths

  • Better for relational data
  • Having a set schema allows you to better understand the structure of your data
  • Data is organized in a way that takes up as little space as possible, improving performance
  • SQL has an easy learning curve
  • Better at handling big data
  • No need for pre-defined schema
  • Cheaper to manage
  • Horizontal scaling

I’ve Decided which Platform to Use, What Now?
