Database: An organised place where an application stores and finds data, such as users, orders or products. MySQL, PostgreSQL, SQL Server and MongoDB are common examples.
Example
When someone signs up, the application saves their details as a new row in the users table.
Why Database matters for IT interns
Almost every application uses one. Basic database knowledge helps you build correct features and debug data problems.
Where you will hear it
You will hear this term in development teams, in code reviews and technical discussions, and in technical interviews. If someone uses it and you are not sure what they mean in your project, it is completely fine to ask; every team uses terms a little differently.
