There are differences between SQL and NoSQL in processing and storing data related to security, reliability, and consistency.
Not many people know the exact terms and differences between SQL and NoSQL, although they often hear about them. Those who are familiar with programming languages are likely to be familiar with the differences between SQL and NoSQL. Unlike NoSQL, SQL is a more familiar term because it is widely used in various organizations and businesses.
The Difference Between SQL and NoSQL, Understanding Them Better
SQL and NoSQL databases are the two most popular, powerful, and valuable types of databases, each with its own way of functioning. SQL databases are relational databases that use Structured Query Language (SQL) to store, retrieve, and manipulate data. On the other hand, NoSQL is a non-relational database that does not use a traditional table-based relational database structure. To have a deeper understanding of these two database terms, here are their explanations.
SQL
It is a relational database where data is organized into tables, and each table has a specific structure. The tables are interconnected, making it very strong in storing data.
NoSQL
It is a non-relational database where data is stored in a collection of documents, and there is no fixed structure. These documents are not interrelated, making it more suitable for data that doesn’t need to be accessed in a specific way.
Their Differences
In terms of scalability, SQL databases use a vertical approach, while NoSQL uses a horizontal approach. Vertical scaling means adding more power to the server, while horizontal scaling means scaling by adding more servers. Another difference is that maintaining a SQL database is more expensive compared to NoSQL because it requires more administration. Additionally, SQL databases are generally more complex than NoSQL because they have to follow ACID rules. This actually makes them slower and more complicated compared to NoSQL databases. ACID in SQL stands for atomicity, consistency, isolation, and durability, which means data is stored securely, reliably, and consistently. NoSQL, which does not follow ACID rules, is more flexible in storing and processing data. However, it also means that data is not always stored securely, cannot be relied upon, and lacks consistency.
By knowing all these aspects related to the differences between SQL and NoSQL, you can choose which one is better to use for storing data.
