Relational Database Comparison – Alibaba, Amazon, Google, IBM and Microsoft

Relational database

Are you handling your client’s data, or recording transaction information? What about dealing with other systems or generating new data? Or, storing data from computers, phones, or IoT devices?

In the matter concerning the use of data and their structured storage, databases have become practically essential. Of the various ways in which companies can store data, establishing a relational database that runs on cloud computing platforms would appear to be among the most straightforward.

Relational databases offer a declarative method for identifying data that are put in tables and rows. They are built based on SQL (Structured Querying Language) that helps to extract and manipulate the data from associated tables in a database.

Relational databases are useful in handling highly structured data and offer support for ACID (Atomicity, Consistency, Isolation, and Durability) transactions. They also allow avoiding data duplication.

Current market trends of relational databases  

Over the years, relational databases have become better, stronger, faster, and easier to work with. They have become the most widely accepted model for databases. A survey by StackOverflow’s developers found that 58.7% of organizations do prefer SQL or relational databases over other databases.

Also, the relational databases will account for over 80% of the total operational database market by 2022, according to IDC.

This confirms that more and more organizations will be using relational models in the coming years.

While it is still possible that companies can opt to build their own server database in the cloud, they can preferably choose to buy a relational database as a service, like ApsaraDB for RDS offered by Alibaba Cloud. What could be easier?

In this post, we are focusing on the best relational databases and comparing them to help you select the most suitable one for your next project.
