RDBMS vs NoSQL: What’s the Difference?
When it comes to organizing data, people usually think of spreadsheets first, but if you or your business have a lot of data to manage, you could benefit from using a database instead.
There are two main types to consider when deciding on a database: relational and non-relational databases.
Keep reading to learn about the differences between these two types of databases.
What Is a Database?
A database is a structured or organized collection of data typically stored electronically. This allows the data to be easily accessed, managed and updated. In addition, databases are usually characterized by the fact that they can store real-time data, provide data security by giving a logical view of the data manipulation, and have properties that help manage data health in case of failure.
A database management system usually controls a database, and most databases use structured query language (SQL) to write and query data.
What Is RDBMS?
Relationship Database Management System (RDBMS) is an advanced version of databases that uses a structure to identify and access data concerning another piece of data in the database. Data in a relational database is organized using tables with columns and rows as it allows for an efficient and flexible way to access structured information.
A relational database also uses normalization to reduce data redundancy.
It is the process used to eliminate data redundancies by correcting the table structure inside the database.
What Is NoSQL?
A non-relational database (NoSQL) allows unstructured data to be stored and accessed. A NoSQL database is flexible and will enable you to store non-tabular data. NoSQL databases are identifiable by flexible schemas, horizontal scaling, fast queries and is generally developers preferred database.
A NoSQL database is generally used when there is a high volume of data, when there is a combination of structured and unstructured data present, or when there is a need for future scale-out architecture.
RDBMS vs NoSQL?
While there are a variety of differences RDBMS and NoSQL databases, the main difference is the way the data is modeled in the database.
RDBMS has a fixed schema, meaning structured data needs to be inserted in the proper format, whereas NoSQL allows for unstructured data. This causes the RDBMS database to structure the data the same way between different tables where NoSQL data won’t be equal.
Since NoSQL does not have a fixed schema, it is difficult for new users to figure out the data pattern.
Lastly, maintenance of RDBMS is expensive, whereas NoSQL maintenance is mainly done automatically.
Save Time by Using a Database
Databases are the safest and most convenient way to organize, view, and modify your data. Keep RDBMS vs NoSQL in mind when deciding which works best for you. Not only will your data be easier to manage, but you’ll also be saving time by converting to a database.
