10 Most Popular Databases You Should Know Apart From MySQL

Databases are everywhere these days, every application uses databases to store, organize and retrieve data. It has become more efficient than paper storage since it does not require more space and can also be easily accessed by multiple users at a time. There is an increase in demand for processing vast collections of data and this has become the most important reason for several companies to use databases. The database is the core element in any applications since it stores the most important data that is required to run any application or software.

Data powers everything that we do

It will be very difficult to find data manually from files or a particular record with millions of data. Using a database you can easily retrieve specific data with queries. You can also add, delete, update data and can be used in many aspects without any hindrance. Here are a few well-known examples where databases are used.

  • Social Media - Used in storing user information
  • Online Television Streaming - Uses the database to generate the list of shows to keep track of the users’ preferences and provides a list of recommended viewing
  • E-Commerce - Stores products, pricing, user, user purchase history information which might help organize and recommend the feasible products to the customers.
  • HealthCare - Db helps in storing patient data and other pharmaceutical information.

StackOverflow, a question and answer platform surveyed about more than 65,000 developers and collected information on the most used database in the year 2020. MySQL has maintained the top position every year followed by PostgreSQL and Microsoft SQL Server.
