As a back end developer, the websites you create will interact with other hardware and software systems. One of the systems many websites exchange data with is a relational database. Even though it is not your responsibility to manage the databases, you should have a good working knowledge of them so your code can exchange data between your website and the database. The interviewer will expect you to at least be familiar with this and be able to discuss it.

"The properties of a relational database are often described using the acronym ACID. This stands for:
Atomicity - A property that guarantees that if any part of a transaction fails, the entire transaction will fail. This prevents database errors.
Consistency - This ensures that every transaction moves the database from one state to another valid one.
Isolation - This addresses the concurrent execution of transactions resulting in the system state that serial transactions create.
Durable - This ensures that executed transactions are maintained, even if the power is lost."
